Activity: Temperature Differences Among

Various Parts of the Body

Equipment required : PS-2143 Quad Temp. Sensor, PASPORT interface, DataStudio

(1.9.0 or later), up to four Fast Response Temperature Probes, adhesive patches/tape

1. Plug the PS-2143 Quad Temp. Sensor into a PASPORT interface.

2. Connect the PASPORT interface to a USB-compatible computer.

3. Launch DataStudio.

4. Plug a Fast Response Temperature Probe into each of the ports on the Quad

Temp. Sensor box.

5. (Optional): Calibrate each of the probes using the calibration procedure on card

2B.

6. Place a probe in each of the following locations: a) chest b) abdomen c) upper arm and d) leg. ( Note: To hold the probes in place, put an adhesive patch or piece of medical tape over each probe.)

7. In DataStudio, open a Graph display. From the Data list, drag the icons for the temperature measurements to the graph.

8. Click the Start button to begin collecting data.

9. Ask the student to exercise vigorously for about 10 minutes, and watch the data while exercising. Stop and rest for about 10 minutes.

10. To end data collection, click the Stop button.

11. Compare the body temperature at each of the four locations during exercise. At which location was the body temperature a) the lowest and b) the highest? At which point was the change in temperature the greatest? Explain your answers.

Do more muscular parts of the body generate more or less heat than those parts with more fat tissue?

12. (Optional): With disposable thermometers, have each student take his/her body temperature. During exercise, which is higher, the core body temperature or the skin temperature? Explain your answers.

13. (Optional): Using skin calipers, take a skinfold measurement for the chest, abdomen, arm, and leg. Is there a relationship between the temperature increase and the skinfold measurement?

Calibrating the Temperature Probe

Calibration of the Fast Response Temperature Probe or Stainless Steel Temperature

Probe (PS-2153) is not required. The accuracy of the PASCO temperature probes is better than 0.5

° C across the entire range of the probe. However, if you wish to calibrate, the probe may be calibrated using the following procedure.

Equipment required: DataStudio software (ver.1.9.0 or later), PS-2143 Quad

Temperature Sensor, temperature probes, ice water, boiling water

1. Plug the PS-2143 Sensor into a PASPORT interface connected to a USBcompatible computer.

2. Plug a temperature probe into the sensor box using any of the four 3.5 mm ports on the sensor box.

3. Click the Setup button in the DataStudio toolbar. The Setup window will open.

4. Click on the Temperature Calibrate button next to the appropriate probe number in the Setup window. The Calibrate window will open.

5. Place the temperature probe in an ice water bath.

6. Ensure the value in the dialogue box for Point 1 is 0. This value may be changed to the temperature of the controlled temperature bath if it is different than 0 ° C.

7. Click the Set button adjacent to the Point 1 dialogue box.

8. Place the temperature probe in boiling water.

9. Ensure the value in the dialogue box for Point 2 is 100. This value may be changed to the temperature of a controlled temperature bath if it is different than 100 ° C.

10. When the displayed current value stops changing, click the Set button adjacent to the Point 2 dialogue box.

11. To save the calibration values, click the OK button. The calibration is complete.

CARD 2A

Collecting Data with the Quad

Temperature Sensor

1. Plug one or more temperature probes into one or more of the external ports.

2. Connect a PASPORT interface to a USB port on your computer or to an

Xplorer.

3. Connect the Quad-Temp Sensor to a PASPORT interface.

4. In DataStudio or Xplorer, click the Start button to begin collecting data. To end data collection, click the Stop button.

Changing Measurements in DataStudio

To change units, click the down arrow next to the appropriate temperature probe number.

Note: To activate recording for a specific probe, click to place an

“X” in the box next to the probe that matches the probe’s port number. To stop the sensor from recording temperature for a specific probe, disconnect the probe or click in the appropriate box to remove the “X.”

Sensor Usage Tips

CAUTION: To avoid damaging the sensor box, do not place the

Quad Temperature box in water, liquids, chemicals, ovens, or fire at any time.

CAUTION: Do not use the sensor beyond the recommended temperature specification range on card 1A.

Tip: DataStudio 1.9.0 will automatically detect when a temperature probe is first connected. The temperature measurement can be manually added in the Setup window.

Tip: If using the Quad Temperature to take freezer measurements, put the probe in the freezer, but keep the box outside of the freezer.

Tip: the stainless steel temperature probe is slightly smaller than the holes in most rubber stoppers. In order to create an airtight seal, use the blue plastic tubing that accompanies the sensor. When slid over the probe, as in the picture below, the seal will be complete.
