INTRODUCTION
The Water kit contains
• Teacher Toolkit: Water
1 Investigations Guide: Water
1 Teacher Resources: Water
1 FOSS Science Resources: Water
• FOSS Science Resources: Water
(class set of student books)
•
Equipment for 32 students
A new kit contains enough consumable items for at least two
classroom uses before you need to resupply. FOSS modules use
central materials distribution. You organize all the materials for an
investigation on a single table called the materials station. As the
investigation progresses, one member of each group gets materials
as they are needed, and another returns the materials when the
investigation is completed. You place items at the station—students
do the rest.
Individual photos of each piece of FOSS equipment are available
online for printing. For updates to information on materials used in
this module and access to the Materials Safety Data Sheets (MSDS),
go to FOSSweb (www.FOSSweb.com). Links to replacement-part
lists and customer service are also available on FOSSweb.

PREPARING a New Kit
If you are preparing a new kit for classroom use, you can do several
things initially that will save time during routine preparation for
instruction.
1. Acquire pennies
Collect 50 pennies and put them in a bag. Store them in the kit.
2. Purchase liquid dishwashing detergent
Add a small bottle of liquid dishwashing detergent to the kit.
3. Purchase vinegar
Add a small bottle of white vinegar to the kit.
4. Put pointers on balances
Find the balance pointers. Insert one, rounded end first, into each
balance beam. Leave the pointers on the balances when you store
them again.

PREPARING the Kit for
Your Classroom
Some preparation is required each time you use the kit. Doing these
things before beginning the module will make daily setup quicker and
easier.
1. Check consumable materials
A number of items in the kit are listed as consumable. Some
of these items will be used up during the investigations (food
coloring, rock salt, filter papers, self-stick notes, potting soil), and
others will wear out and need replacement (glue sticks). The rolls
of aluminum foil and waxed paper and the ball of string will last
for many uses but eventually will need replacement. Any items that
cannot be reused for the particular FOSS investigation might be
usable in another part of the curriculum. Before throwing items
out, consider ways to recycle them, and get your students involved
in this process.
2. Check food coloring
To enhance observations, food coloring is added to water in several
of the investigations. Color is also used to indicate temperature.
Green is added to room-temperature water, blue to cold or ice
water, and red to hot water. The three plastic dispensing bottles are
used to mix and store the colored water. Recipes are discussed in
the Getting Ready sections.
Check to see that there is a good supply of the three colors needed
for this module.
3. Check gravel and soil
Check the quantity of gravel and soil. You need about a half-liter
of gravel and a liter of soil for the class.
4. Inventory cups
There are two sizes of plastic cups used in this module. The
standard cup holds about 250 mL (9 oz.) and is called the small
plastic cup. The other cup is large and holds about 500 mL
(16 oz.).
The plastic filter cups in the kit look the
same as the small plastic cup, except that
filter cups have holes in the bottom. Check
carefully each time you get out cups in this
module that you have the appropriate cup for
the investigation.

5. Check mass sets
Each group will need a set of mass pieces in a liter-size zip bag.
Inventory each of the eight bags for these 33 pieces.
25 1 g pieces
5 5 g pieces
2 10 g pieces
1 20 g piece
6. Protect the hand lenses
Check the hand lenses to make sure each is in a protective plastic
cover (bag). Replace any covers that are missing.
7. Inventory labels
Labels are used on cups and dome lids throughout the module.
Self-stick notes are provided for this purpose because they are
handy and easy to remove. If they come off before you want them
to, anchor them with a small piece of transparent tape.
8. Plan for a water source
Water is needed for each investigation. In many cases roomtemperature water is required; in others hot water, cold water, or
ice. Plan ahead to make sure that water is at hand. If you don’t
have a water supply in your classroom, fill pitchers with water. A
large bucket can be used to collect liquids when no sink is available
or when plain water is to be recycled.
Hot water can be kept hot in a vacuum bottle or an electric
hot-water pot. You could use a hot plate to heat the water and
introduce students to this tool used in the laboratory. Be sure
you have adequate supervision before using the hot plate in the
classroom.
Keep water and ice cold in an ice chest.
For outdoor activities that use water, save and reuse plastic gallon
jugs or 2-L plastic bottles.
9. Locate a freezer
In Investigation 2, students fill vials and syringes with water and
freeze them overnight. Locate some freezer space at your school
for these items.
10. Collect water bottles
Collect a couple of recycled gallon plastic jugs or 2 L soft-drink
bottles with caps for carrying a water supply outdoors.
11. Plan for cleanup
This module uses containers and tools that must be cleaned,
dried, and inventoried if they are to stay in top condition.
This responsibility should be assumed by students. Assign one
collaborative group to do this after each session. Plan where this
cleanup will take place in the classroom (if you have a sink) or
elsewhere in the school if a sink is not available in your room.
44
Full Option Science System
All the plastic items in the kits are meant to be rinsed, dried,
and reused.
Also plan for the disposal of liquids. A collection bucket works well
when there is no sink.
12. Consider safety issues indoors and outdoors
Two safety posters are included in the kit, one for science indoors
and one for working outdoors. You should review the guidelines
with students and post the posters in the room as a reminder.
Getting Ready for Investigation 1, Part 1, offers suggestions for this
discussion. Also be aware of any allergies that students in your class
might have.
The label in the sidebar is required in this Investigation Guide by the
US Consumer Product Safety Commission (CPSC) because the kit
contains cobalt chloride test paper (see Investigation 3, Part 5).
13. Photocopy notebook sheets
You will need to make copies of science notebook sheets before
each investigation. See Getting Ready for Investigation 1, Part 1,
for ways to organize the science notebook sheets for this module.
If you use a projection system, you can download electronic copies
of the sheets from FOSSweb (www.FOSSweb.com).
14. Check FOSSweb for resources
Go to FOSSweb to review the print and digital resources available
for this module.
15. Plan for word wall
As the module progresses, you will add new vocabulary words to
a word wall or pocket chart, and model writing and responding to
focus questions. Plan how you will do this in your classroom.
You may also find it beneficial to use a pocket chart to display the
equipment photo cards as reference for students as they gather
needed items from the materials station for each part. Print the
photo cards from FOSSweb.
16. Acquire books from library
Check your local library for books. Visit FOSSweb for a list of
appropriate trade books that relate to this module.
17. Plan for letter home and home/school
connections
You will need to make copies of teacher master 1, Letter to Family,
rs
for the module and the Home/School Connection teacher masters
for each investigation.
Water Module
TEACHING NOTE
The Letter to Family and
Home School Connections are
also available electronically on
FOSSweb.

CARE, Reuse, and Recycling
When you finish teaching the module, inventory the kit carefully. Note
the items that were used up, lost, or broken, and immediately arrange
to replace the items. Use a photocopy of the materials list (the Kit
Inventory List), and put your marks in the “Equipment Condition”
column. Refill packages and replacement parts are available for FOSS
by calling Delta Education at 1-800-258-1302 or by using the online
replacement-part catalog (www.DeltaEducation.com).
Standard refill packages of consumable items are available from Delta
Education. A refill package for a module includes sufficient quantities
of all consumable materials (except those provided by the teacher) to
use the kit with two classes of 32 students.
Here are a few tips on storing the equipment after use.
•
•
•
•
•
•
•
Keep the balance pointers on the balances.
Rinse pennies in vinegar, rinse with water, dry, and store.
Inventory and bag the small items.
Make sure items are clean and dry before storing them.
Dry gravel and return it to its container.
Secure the lids on all containers of materials and on the food
coloring. Make sure the soil bag and gravel container are tightly
sealed.
Check quantity of consumables and order more if necessary.
The items in the kit have been selected for their ease of use and
durability. Make sure that items are clean and dry before putting them
back in the kit. Small items should be inventoried (a good job for
students under your supervision) and put into zip bags for storage. Any
items that are no longer useful for science should be properly recycled.
