In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

Visitors observe three beakers. One beaker contains an egg immersed in vinegar. Visitors observe carbon dioxide gas escaping from the shell as the calcium carbonate reacts with the vinegar.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

Learners take on the role of environmental engineers as they design water filters.
