In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

In this activity (1st on the page), learners explore circadian rhythms by keeping track of their body temperature.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity, learners will determine if the frequency and intensity of hurricanes are changing using real data from the National Hurricane Center.

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
