MATERIALS TO BE USED
●
●
●
identical large, empty glass jars (2)
lid for one jar
non mercury thermometers (2)

●
Lay a thermometer inside each jar.
Place the jars next to each other by a sunny window.
Record the temperatures of the two thermometers. They should be the same.
Place the lid on one jar.
Record the temperatures of all three thermometers at the end of 5, 10, 15, 20 and 25
min.
Plot your data on the graph in the Data and Observations section that shows the
temperatures of the three thermometers for the 25 minutes of the experiment.
DATA & OBSERVATION: State the outcome of the experiment. Include graphs
and/or tables if applicable.
CONCLUSION
1. Explain why you placed thermometers inside the two jars.
2. List the constants in this experiment?
3. What was the variable in the experiment?
4. Identify which thermometer showed the greatest temperature change during your
experiment.
5. Analyze what occurred in this experiment. How was the lid in this experiment like the
greenhouse gases in the atmosphere?
6. Infer from this experiment why you should never leave a pet inside a closed car in
warm weather.
