In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

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 discover if carbon dioxide has an effect on temperature.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

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