Investigation 1
CO 2 is released in the reaction (just like in the demos). This models an increase in greenhouse gas.
While the jars heat up at about the same rate, the one with CO 2 cools down much more slowly.

Investigation 2
This models how CO 2 and water vapor in the atmosphere affect the rate at which the Earth loses
heat (the plastic wrap acts as the CO 2 and water vapor during the experiment).

Investigation 3
This is similar to Investigation #2. This models how CO 2 and water vapor in the atmosphere affect
the rate at which the Earth gains and loses heat (the plastic wrap acts as the CO 2 and water vapor
during the experiment).

Investigation 4
This models how the temperature of the actual Earth changes (as opposed to water in investigations
#2 and #3). The plastic wrap acts as the greenhouse gases.
