In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

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

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

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.

Learners will build and experiment with their own windmills made from simple household materials.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this lesson, learners will practice graphing and statistically analyzing data.
