In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.
