OHIO’S NEW LEARNING STANDARDS I Science 106 BACK TO INDEX Grade 4 BACK TO K-8 INDEX INTRODUCTION TO CONTENT STATEMENTS GRADE BAND THEME: INTERCONNECTIONS WITHIN SYSTEMS This theme focuses on helping students recognize the components of various systems and then investigate dynamic and sustainable relationships within systems using scientific inquiry. SCIENCE INQUIRY AND APPLICATION During the years of PreK-4, all students must become proficient in the use of the following scientific processes, with appropriate laboratory safety techniques, to construct their knowledge and understanding in all science content areas: • Observe and ask questions about the natural environment; • Plan and conduct simple investigations; • Employ simple equipment and tools to gather data and extend the senses; • Use appropriate mathematics with data to construct reasonable explanations; • Communicate about observations, investigations and explanations; and • Review and ask questions about the observations and explanations of others. STRANDS Strand Connections: Heat and electrical energy are forms of energy that can be transferred from one location to another. Matter has properties that allow the transfer of heat and electrical energy. Heating and cooling affect the weathering of Earth’s surface and Earth’s past environments. The processes that shape Earth’s surface and the fossil evidence found can help decode Earth’s history. EARTH AND SPACE SCIENCE (ESS) PHYSICAL SCIENCE (PS) LIFE SCIENCE (LS) Topic: Earth’s Surface Topic: Electricity, Heat and Matter Topic: Earth’s Living History This topic focuses on the variety of processes that shape and reshape Earth’s surface. This topic focuses on the conservation of matter and the processes of energy transfer and transformation, especially as they relate to heat and electrical energy. This topic focuses on using fossil evidence and living organisms to observe that suitable habitats depend upon a combination of biotic and abiotic factors. CONDENSED CONTENT STATEMENTS • Earth’s surface has specific characteristics and landforms that can be identified. • The surface of Earth changes due to weathering. • The surface of Earth changes due to erosion and deposition. • The total amount of matter is conserved when it undergoes a change. • Energy can be transformed from one form to another or can be transferred from one location to another. • Changes in an organism’s environment are sometimes beneficial to its survival and sometimes harmful. • Fossils can be compared to one another and to present day organisms according to their similarities and differences. OHIO’S NEW LEARNING STANDARDS I Science 107 BACK TO INDEX MODEL CURRICULUM GRADE 4 BACK TO K-8 INDEX EARTH AND SPACE SCIENCE (ESS) Topic: Earth’s Surface This topic focuses on the variety of processes that shape and reshape Earth’s surface. CONTENT STATEMENT CONTENT ELABORATION Earth’s surface has specific characteristics and landforms that can be identified. Prior Concepts Related to Surface of Earth About 70 percent of the Earth’s surface is covered with water and most of that is the ocean. Only a small portion of the Earth’s water is freshwater, which is found in rivers, lakes and ground water. Earth’s surface can change due to erosion and deposition of soil, rock or sediment. Catastrophic events such as flooding, volcanoes and earthquakes can create landforms. PreK-2: Wind and precipitation can be measured, water can change state, heating and freezing can change the properties of materials, and living things can cause changes on Earth. Grade 3: The composition and characteristics of rocks and soil are studied. Grade 4 Concepts Earth is known as the Blue Planet because about 70 percent of Earth’s surface is covered in water. Freshwater is a small percentage of the overall water found on Earth; the majority is oceanic. There are many different processes that continually build up or tear down the surface of Earth. These processes include erosion, deposition, volcanic activity, earthquakes, glacial movement and weathering. Beginning to recognize common landforms or features through field investigations, field trips, topographic maps, remote sensing data, aerial photographs, physical geography maps and/or photographs (through books or virtually) are important ways to understand the formation of landforms and features. Common landforms and features include streams, deltas, floodplains, hills, mountains/mountain ranges, valleys, sinkholes, caves, canyons, glacial features, dunes, springs, volcanoes and islands. Connecting the processes that must occur to the resulting landform, feature or characteristic should be emphasized. This can be demonstrated through experiments, investigations (including virtual experiences) or field observations. Technology can help illustrate specific features that are not found locally or demonstrate change that occurred (e.g., using satellite photos of an erosion event such as flooding). Future Application of Concepts Grade 5: Earth is a planet in the solar system that has a unique composition. Global seasonal changes are introduced, including monsoons and rainy seasons, which can change erosion and deposition patterns. Grades 6-8: Changes in the surface of Earth are examined using data from the rock record and through the understanding of plate tectonics and the interior of Earth. Historical studies of erosion and deposition patterns are introduced, in addition to soil conservation, the interaction of Earth’s spheres and ocean features specific to erosion and deposition. EXPECTATIONS FOR LEARNING: COGNITIVE DEMANDS This section provides definitions for Ohio’s science cognitive demands, which are intrinsically related to current understandings and research about how people learn. They provide a structure for teachers and assessment developers to reflect on plans for teaching science, to monitor observable evidence of student learning, and to develop summative assessment of student learning of science. OHIO’S NEW LEARNING STANDARDS I Science 108 BACK TO INDEX BACK TO K-8 INDEX VISIONS INTO PRACTICE: CLASSROOM EXAMPLES This section provides examples of tasks that students may perform; this includes guidance for developing classroom performance tasks. It is not an all-inclusive checklist of what should be done, but is a springboard for generating innovative ideas. DESIGNING TECHNOLOGICAL/ ENGINEERING SOLUTIONS USING SCIENCE CONCEPTS DEMONSTRATING SCIENCE KNOWLEDGE INTERPRETING AND COMMUNICATING SCIENCE CONCEPTS RECALLING ACCURATE SCIENCE Research a specific weathering feature (such as a sinkhole or cave). Evaluate the risk of collapse and methods of prevention of collapse (using actual data) and recommend one solution based on the scientific data. Create a model (virtual, graphic or 3-D) of the actual cave or sinkhole and demonstrate the risk of collapse and how the suggested preventative measure or solution impacts that risk. Plan, build and use a model (such as a small-scale stream table) that can demonstrate the formation of a landform or feature that formed through contact with water (alluvial fan, sinkhole, midchannel bar, canyon, valley, depositional islands). Ask: What factors accelerate the processes? What factors must exist for the landform to form? Share findings with the class. Using topographic or aerial maps, locate areas that have been formed through deposition and erosion. Recognize that 70 percent of Earth’s surface is water, which is why Earth is known as the Blue Planet. Include areas of Ohio that have been impacted by glacial ice or movement. Discuss findings with the class. Identify common landforms from maps or graphics. Using LANDSAT data, research and locate a specific major landform or geographical feature on Earth that formed through erosion or deposition. Represent findings graphically or orally to the class. Identify the processes that can change the surface of Earth (e.g., erosion, deposition, volcanic activity, earthquakes, glacial movement and/or weathering). OHIO’S NEW LEARNING STANDARDS I Science 109 BACK TO INDEX BACK TO K-8 INDEX INSTRUCTIONAL STRATEGIES AND RESOURCES This section provides additional support and information for educators. These are strategies for actively engaging students with the topic and for providing hands-on, mindson observation and exploration of the topic, including authentic data resources for scientific inquiry, experimentation and problem-based tasks that incorporate technology and technological and engineering design. Resources selected are printed or Web-based materials that directly relate to the particular Content Statement. It is not intended to be a prescriptive list of lessons. • Fieldtrips to local caves, caverns, sinkholes, glacial areas, stream systems, lakes, etc., should be encouraged to experience Ohio geologic landforms and features first hand. There also are numerous virtual fieldtrips to visit caves, canyons, glaciers, mountains and valleys. • The Ohio Department of Natural Resources provides helpful resources and geologic maps that can be used to study landforms and surface geology of Ohio. The relationship between the types of rocks and the resulting features or landforms is a very important connection, especially if local/regional maps are used in conjunction with field trips or outside investigations around the community or school property. • Viewing landforms and surface geology from satellite photographs and through remote sensing can be a helpful tool in illustrating landforms in different parts of the world and conditions that exist for formation. Click on the geographical features icon to see satellite photos of Earth’s surface. •The NASA Visible Earth Program houses hundreds of satellite photos that can be used to illustrate specific landforms. Comparing the photo to a map can be a good way to learn about recognizable features such as delta systems, mountain ranges, volcanoes and canyons. •The National Atlas mapmaker site can plot areas within the United States where specific geologic features are found. For example, by clicking on Geology, then the Karst, Engineering Aspects option, areas that have caves, caverns and sinkholes are shown. This can be a good starting resource to locate other maps, photos and graphics related to landforms and features that form through erosion and/or deposition. •The USGS website provides data, information, books and maps that relate to Earth’s surface, weathering and erosion. Many of these resources are free and some are available at cost. •The National Speleological Society provides information and resources for caves and caving for young students. Taking a field trip to an Ohio cave connects what is learned in the classroom about weathering and erosion to the real world. It is essential to learn about the processes of cave formation and karts topography, including lab investigations, to prepare students for a cave or cavern field experience.

OHIO’S NEW LEARNING STANDARDS I Science 111 BACK TO INDEX MODEL CURRICULUM GRADE 4 BACK TO K-8 INDEX EARTH AND SPACE SCIENCE (ESS) Topic: Earth’s Surface This topic focuses on the variety of processes that shape and reshape Earth’s surface. CONTENT STATEMENT CONTENT ELABORATION The surface of Earth changes due to weathering. Prior Concepts Related to Weathering Rocks change shape, size and/or form due to water or ice movement, freeze and thaw, wind, plant growth, gases in the air, pollution and catastrophic events such as earthquakes, mass wasting, flooding and volcanic activity. Note: The ice movement (above) refers to large bodies of ice, such as glaciers that can break large rocks into small ones. PreK-2: Wind is moving air, water and wind have measurable properties, water changes state, properties of materials change when exposed to various conditions (e.g., heating, freezing) and living organisms interact with their environment. Grade 3: Rocks and soil have unique characteristics. Soil contains pieces of rock. Grade 4 Concepts Different types of rock weather at different rates due to specific characteristics of the rock and the exposure to weathering factors (e.g., freezing/thawing, wind, water). Weathering is defined as a group of processes that change rock at or near Earth’s surface. Some weathering processes take a long time to occur, while some weathering processes occur quickly. The weathering process must be observed in nature, through classroom experimentation or virtually. Seeing tree roots fracturing bedrock or the effect of years of precipitation on a marble statue can illustrate ways that rocks change shape over time. Investigations can include classroom simulations, laboratory testing and field observations. Future Application of Concepts Grade 5: Earth is a planet in the solar system that has a unique composition, global seasonal changes and patterns are introduced, including temperature fluctuations/ranges, monsoons and/or rainy seasons which can impact the weathering of Earth’s surface. Grades 6-8: The relationship between the characteristics of rocks and the environment in which they form is explored as well as how rocks break down (weather) and are transported (erosion), water flows through rock and soil at different rates, and the causes of changes on Earth’s surface.

OHIO’S NEW LEARNING STANDARDS I Science 114 BACK TO INDEX MODEL CURRICULUM GRADE 4 BACK TO K-8 INDEX EARTH AND SPACE SCIENCE (ESS) Topic: Earth’s Surface This topic focuses on the variety of processes that shape and reshape Earth’s surface. CONTENT STATEMENT CONTENT ELABORATION The surface of Earth changes due to erosion and deposition. Prior Concepts Related to Erosion and Deposition Water, wind and ice physically remove and carry (erosion) rock, soil and sediment and deposit the material in a new location. Gravitational force affects movements of water, rock and soil. PreK-2: Wind is moving air, water and wind have measurable properties, water changes state, forces change the motion of an object and some forces act without touching (e.g., gravitational forces). Grade 3: Soil and rock have unique characteristics. Soil and rock are nonliving resources that can be conserved. Grade 4 Concepts Erosion is a process that transports rock, soil or sediment to a different location. Weathering is the breakdown of large rock into smaller pieces of rock. Erosion is what carries the weathered material to a new location. Gravity plays an important role in understanding erosion, especially catastrophic events like mass wasting (e.g., mudslides, avalanches, landslides) or flooding. Erosion is a “destructive” process and deposition is a “constructive” process. Erosion and deposition directly contribute to landforms and features formation that are included in grade 4. Topographic maps and aerial photographs can be used to locate erosional and depositional areas in Ohio. Surficial geology maps also can illustrate the patterns of glacial erosion and deposition that have occurred. Field trips and field investigations (may be virtual) are recommended as erosional and depositional features that can be seen locally or within the state can help to connect the concept of erosion and deposition to the real world. Future Application of Concepts Grade 5: Earth is a planet in the solar system that has a unique composition, global seasonal changes are introduced, including monsoons and rainy seasons, which can change erosion and deposition patterns. Grades 6-8: Historical studies of erosional and depositional patterns are introduced, in addition to soil conservation, the interaction of Earth’s spheres, ocean features specific to erosion and deposition, and plate tectonics.

It is not an all-inclusive checklist of what should be done, but is a springboard for generating innovative ideas. DESIGNING TECHNOLOGICAL/ ENGINEERING SOLUTIONS USING SCIENCE CONCEPTS DEMONSTRATING SCIENCE KNOWLEDGE INTERPRETING AND COMMUNICATING SCIENCE CONCEPTS RECALLING ACCURATE SCIENCE Sediment fences are often placed around construction sites to help control sediment from moving offsite (erosion) into the surrounding environment (deposition). Design and construct a model of one specific sediment-control measure (using scientific research). Evaluate and test it using different types of materials. Different groups in the class should model different methods of control. Use actual geologic data from a specific location, such as the Grand Canyon. Research the formation of the canyon. Ask: Why does some rock weather and erode faster than others? What caused the weathering and erosion in the canyon? How can the age of the canyon be estimated? Differentiate between weathering and erosion. Identify erosion as a process that transports rock, soil or sediment to a new location. Compare and contrast erosion and deposition. Identify deposition as the settling or coming to rest of transported rock, soil or sediment. Use the research data to make a geologic cross section (3-D or virtual model or a graphic) to model the canyon. Each group should present findings and demonstrate the models. Using a surficial geology map of Ohio, trace the patterns of glacial movement that can be recognized by a variety of glacial deposits or erosion. Build a model to investigate the movement of glacial ice that creates a similar pattern. Ask: What factors must exist to support the movement of glaciers? Why is glacial movement erosional and depositional?

OHIO’S NEW LEARNING STANDARDS I Science 117 BACK TO INDEX MODEL CURRICULUM GRADE 4 BACK TO K-8 INDEX LIFE SCIENCE (LS) Topic: Earth’s Living History This topic focuses on using fossil evidence and living organisms to observe that suitable habitats depend upon a combination of biotic and abiotic factors. CONTENT STATEMENT CONTENT ELABORATION Changes in an organism’s environment are sometimes beneficial to its survival and sometimes harmful. Prior Concepts Related to Behavior, Growth and Changes Ecosystems can change gradually or dramatically. When the environment changes, some plants and animals survive and reproduce and others die or move to new locations. An animal’s patterns of behavior are related to the environment. This includes the kinds and numbers of other organisms present, the availability of food and resources, and the physical attributes of the environment. PreK-2: Plants and animals have variations in their physical traits that enable them to survive in a particular environment. Living things that once lived on Earth no longer exist, as their needs were not met. Living things have basic needs, which are met by obtaining materials from the physical environment. Grade 3: Plants and animals have life cycles that are part of their adaptations for survival in their natural environments. Grade 4 Concepts Ecosystems are based on interrelationships among and between biotic and abiotic factors. Ohio has experienced various weather patterns. Some parts of Ohio hosted glaciers and other parts of Ohio were submerged with water. Ecosystems can change rapidly (e.g., volcanoes, earthquakes, or fire) or very slowly (e.g., climate change). Major changes over a short period of time can have a significant impact on the ecosystem and the populations of plants and animals living there. The changes that occur in the plant and animal populations can impact access to resources for the remaining organisms, which may result in migration or death. The fossil record provides evidence for changes in populations of species. Researching and investigating specific areas in Ohio (e.g., Cedar Bog, Lake Erie, Hocking Hills, Ceasar Creek, Kellys Island) via field studies, virtual field trips or other references must be used to explore the relationships between previous environments, changes that have occurred in the environments and the species that lived there. Note: Grade 4 ES focuses on changes to Earth’s surface due to erosion, deposition of soil, rock sediment, flooding, volcanoes and earthquakes that can be taught along with this content. Future Application of Concepts Grades 6-8: Organisms that survive pass on their traits to future generations. Climate, rock record and geologic periods are explored in Earth and Space Science. High School: The concepts of evolution are explored.

DESIGNING TECHNOLOGICAL/ ENGINEERING SOLUTIONS USING SCIENCE CONCEPTS DEMONSTRATING SCIENCE KNOWLEDGE INTERPRETING AND COMMUNICATING SCIENCE CONCEPTS RECALLING ACCURATE SCIENCE Critique plans (written or oral) from different organizations to reintroduce a species into an Ohio environment. Write a newspaper article in support or against the reintroduction of the species based upon scientific facts. Conduct an investigation to determine if removing or adding plants to an area increases or decreases erosion. Ask: How does this impact other organisms in that environment? Read a firsthand description, view drawings of Ohio ecosystems as first observed by explorers and compare the historical environmental descriptions to the current environment. Explain the changes that occurred in the biotic and abiotic components of the ecosystem. Describe the immediate consequences of rapid ecosystem change for organisms within an ecosystem and describe the consequences this change will have on an ecosystem a decade or more later (e.g., flooding, wind storms, snowfall, volcanic eruptions). Research a major geologic event (e.g., Mt. St. Helens volcanic eruption, tsunami). Develop a timeline depicting the environment before the event, immediately after the event and in designated time intervals until a stable community is established (e.g., 30 or more years). Find information at http://www.fs.fed.us/gpnf/mshnvm/ education/teachers-corner/library/ life-returns01.shtml#01.

CONTENT STATEMENT CONTENT ELABORATION Fossils can be compared to one another and to present-day organisms according to their similarities and differences. Prior Concepts Related to Behavior, Growth and Changes The concept of biodiversity is expanded to include different classification schemes based upon shared internal and external characteristics of organisms. Most types of organisms that have lived on Earth no longer exist. Fossils provide a point of comparison between the types of organisms that lived long ago and those existing today. PreK-2: Plants and animals have variations in their physical traits that enable them to survive in a particular environment. Living things that once lived on Earth no longer exist, as their needs were not met. Living things have basic needs, which are met by obtaining materials from the physical environment. Grade 3: Plants and animals have life cycles that are part of their adaptations for survival in their natural environments. Grade 4 Concepts Fossils provide evidence that many plant and animal species are extinct and that many species have changed over time. The types of fossils that are present provide evidence about the nature of the environment at that time. As the environment changed so did the types of organisms that could survive in that environment. The opportunity to learn about an increasing variety of living organisms, both the familiar and the exotic, should be provided. The observations and descriptions of organisms should become more precise in identifying similarities and differences based upon observed structures. Emphasis can still be on external features; however, finer detail than before should be included. Hand lenses and microscopes should be routinely used.

DESIGNING TECHNOLOGICAL/ ENGINEERING SOLUTIONS USING SCIENCE CONCEPTS DEMONSTRATING SCIENCE KNOWLEDGE INTERPRETING AND COMMUNICATING SCIENCE CONCEPTS RECALLING ACCURATE SCIENCE Propose and test multiple ways that living things with soft body parts can leave fossil evidence. Experiment with making fossils to determine some of the necessary (living and nonliving) conditions for making fossils and to determine if similar conditions exist today. Materials used should include clay, dough, sand, mud, etc. Conditions should include moist, wet and dry. Representations of living organisms used should include those with hard body parts (exoskeletons, bones) and those with soft body parts (plants). From observation of fossils in rock layers, infer the environmental conditions that existed when the fossils were formed (e.g., fish fossils would indicate a body of water existed at the time the fossils formed).

OHIO’S NEW LEARNING STANDARDS I Science 124 BACK TO INDEX MODEL CURRICULUM GRADE 4 BACK TO K-8 INDEX PHYSICAL SCIENCE (PS) Topic: Electricity, Heat and Matter This topic focuses on the conservation of matter and the processes of energy transfer and transformation, especially as they apply to heat and electrical energy. CONTENT STATEMENT CONTENT ELABORATION The total amount of matter is conserved when it undergoes a change. Prior Concepts Related to Changes of Matter When an object is broken into smaller pieces, when a solid is dissolved in a liquid or when matter changes state (solid, liquid, gas), the total amount of matter remains constant. Note 1: At this grade, the discussion of conservation of matter should be limited to a macroscopic, observable level. Note 2: States of matter are found in PS grade 3. Heating and cooling is one way to change the state of matter. PreK-2: Simple measuring instruments are used to observe and compare properties of objects. Changes in objects are investigated. Grade 3: Objects are composed of matter, which has weight mass* and takes up space. Matter includes solids, liquids and gases (air). Phase changes are explored. Grade 4 Concepts: Some properties of objects may stay the same even when other properties change. For example, water can change from a liquid to a solid, but the mass* of the water remains the same. Parts of an object or material may be assembled in different configurations, but the mass* remains the same. The sum of all of the parts in an object equals the mass* of the object. When a solid is dissolved in a liquid, the mass* of the mixture is equal to the sum of the masses* of the liquid and solid. At this grade level, the discussion of conservation of matter should be limited to a macroscopic, observable level. Conservation of matter must be developed from experimental evidence collected in the classroom. After the concept has been well established with experimental data and evidence, investigations can include interactions that are more complex where the mass* may not appear to stay constant (e.g., fizzing tablets in water). Note: Mass* is an additive property of objects and volume is usually an additive property for the same material at the same conditions. However, volume is not always an additive property, especially if different substances are involved. For example, mixing alcohol with water results in a volume that is significantly less than the sum of the volumes. Future Application of Concepts Grades 6-8: Conservation of matter in phase changes and chemical reactions is explained by the number and type of atoms remaining constant. The idea of conservation of energy is introduced. *While mass is the scientifically correct term to use in this context, the NAEP 2009 Science Framework (page 27) recommends using the more familiar term “weight” in the elementary grades with the distinction between mass and weight being introduced at the middle school level. In Ohio, students will not be assessed on the differences between mass and weight until Grade 6.

Propose a sustainable plan that might be adopted by a larger population of citizens for minimizing waste products and reserving more space in our landfills. Develop a presentation that could be for an outside audience with the authority to implement the plan within a community. Investigate what happens to the total amount of mass* during many types of changes (e.g., ice melting, salt dissolving, paper tearing, candle burning, Alka-Seltzer® in water). Explain why the volume of water decreases when placed in an open container and left to sit for an extended period of time. Recognize that the amount of matter stays constant during any change. Propose reasons for any difference in the final weight (mass). Design a revised experiment to test proposals. *While mass is the scientifically correct term to use in this context, the NAEP 2009 Science Framework (page 27) recommends using the more familiar term “weight” in the elementary grades with the distinction between mass and weight being introduced at the middle school level.

OHIO’S NEW LEARNING STANDARDS I Science 127 BACK TO INDEX MODEL CURRICULUM GRADE 4 BACK TO K-8 INDEX PHYSICAL SCIENCE (PS) Topic: Electricity, Heat and Matter This topic focuses on the conservation of matter and the processes of energy transfer and transformation, especially as they apply to heat and electrical energy. CONTENT STATEMENT CONTENT ELABORATION Energy can be transformed from one form to another or can be transferred from one location to another. Prior Concepts Related to Heat and Electricity Energy transfers from hot objects to cold objects as heat, resulting in a temperature change. Electric circuits require a complete loop of conducting materials through which an electrical energy can be transferred. Electrical energy in circuits can be transformed to other forms of energy, including light, heat, sound and motion. Electricity and magnetism are closely related. PreK-2: Temperature is a property of objects. Sunlight affects the warming or cooling of air, water and land (ESS). Charged objects can attract uncharged objects and may either attract or repel other charged objects. Magnetic objects can attract things made of iron and may either attract or repel other magnetic objects. Grade 3: Objects that have energy can cause change. Heat, electrical energy, light, sound and magnetic energy are all forms of energy. Grade 4 Concepts: The addition of heat may increase the temperature of an object. The removal of heat may decrease the temperature of an object. There are materials in which the entire object becomes hot when one part of the object is heated (e.g., in a metal pan, heat flows through the pan on the stove transferring the heat from the burner outside the pan to the food in the pan). There are other objects in which parts of the object remain cool even when another part of the object is heated (e.g., in a Styrofoam® cup, very little of the warmth from hot liquid inside the cup is transferred to the hand holding the cup). Electrical conductors are materials through which electricity can flow easily. Electricity introduced to one part of the object spreads to other parts of the object (e.g., copper wire is an electrical conductor because electricity flows through the wires in a lamp from the outlet to the light bulb and back to the outlet). Electrical insulators are materials through which electricity cannot flow easily. Electricity introduced to one part of the object does not spread to other parts of the object (e.g., rubber surrounding a copper wire is an electrical insulator because electricity does not flow through the rubber to the hand holding it). Electrical conductivity must be explored through testing common materials to determine their conductive properties. In order for electricity to flow through a circuit, there must be a complete loop through which the electricity can pass. When an electrical device (e.g., lamp, buzzer, motor) is not part of a complete loop, the device will not work. Electric circuits must be introduced in the laboratory by testing different combinations of electrical components. When an electrical device is a part of a complete loop, the electrical energy can be changed into light, sound, heat or magnetic energy. Electrical devices in a working circuit often get warmer. OHIO’S NEW LEARNING STANDARDS I Science 128 BACK TO INDEX BACK TO K-8 INDEX When a magnet moves in relation to a coil of wire, electricity can flow through the coil. When a wire conducts electricity, the wire has magnetic properties and can push and/or pull magnets. The connections between electricity and magnetism must be explored in the laboratory through experimentation. Note 1: Exploring heat transfer in terms of moving submicroscopic particles is not appropriate at this grade level. Note 2: The word “heat” is used loosely in everyday language, yet it has a very specific scientific meaning. Usually what is called heat is actually “thermal or radiant energy.” An object has thermal energy due to the random movement of the particles that make up the object. Radiant energy is that which is given off by objects through space (e.g., warmth from a fire, solar energy from the sun). “Heating” is used to describe the transfer of thermal or radiant energy to another object or place. Differentiating between these concepts is inappropriate at this grade level. This document uses the same conventions as noted in the NAEP 2009 Science Framework (see page 29) where “heat” is used in lower grades. However, the word “heat” has been used with care so it refers to a transfer of thermal or radiant energy. The concept of thermal energy, as it relates to particle motion, is introduced in grade 6. Note 3: Knowing the specifics of electromagnetism is not appropriate at this grade level. At this point, the connections between electricity and magnetism are kept strictly experiential and observational. Note 4: Energy transfer (between objects or places) should not be confused with energy transformation from one form of energy to another (e.g., electrical energy to light energy). Future Application of Concepts Grade 5: Light and sound are explored further as forms of energy. Grades 6-8: Thermal energy is related to the atomic theory. Kinetic and potential energy are two ways objects can store energy. Conservation of energy and energy transfer through radiation, convection and conduction, and the transfer of electrical energy in circuits are introduced.
