Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, challenge learners to keep an ice cube from completely melting in 30 minutes. Learners engineer a box or wrap to prevent an ice cube from melting.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.
