In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

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

In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.

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

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.
