Lydia designs an experiment to examine the relationship between barometric pressure and temperature. She measures the temperature and the barometric pressure on Monday and Tuesday. She writes up her report and turns it in on Wednesday, the day it’s due. Below are her data and conclusion.

Day	Temperature	Barometric Pressure
Monday	27°C	1011 millibars
Tuesday	28°C	1123 millibars

Conclusion: A rise in temperature causes a rise in barometric pressure.

1. Which of the following would improve Lydia’s experimental design?

a. Test another variable as well.

b. Collect data for more days.

c. Use a mercurial barometer.

d. Measure temperature in Fahrenheit.

e. Use data from another geographic region as a control.

2. Which of the following statements most accurately evaluates the validity of her conclusion?

a. Her conclusion is valid because she organized the data into a table correctly.

b. Her conclusion is valid because she measured temperature and pressure carefully and used metric units.

c. Her conclusion is invalid because it is impossible to determine the relationship between temperature and pressure experimentally.

d. Her conclusion is invalid because nothing in her experiment tests if a change in temperature causes a change in pressure.

Gathering Temperature Readings Using a CBL

Tasks: You have been given a TI-82 calculator, a CBL, a temperature probe, and a "master" calculator that contains appropriate programs. Perform the following:

1. Use these to download the "COOL TEMP" program from the master calculator to your calculator. Then use the program to gather temperature readings from an ecosystem of your choice.

2. Choose two different locations within the same ecosystem and gather temperature readings in these areas.

3. Construct a table, chart, graph, or diagram to display your findings.

4. Write a brief paragraph that summarizes your data and draws conclusions based on your data.

Objective Skill: Students will demonstrate the ability to load programs on a TI-82 and CBL and then use the programmed equipment to gather data.

Materials Needed:
