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

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

In this activity, learners explore how watermills have helped harness energy from water through the ages.

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.

Learners explore the relationship between energy consumption, population, and carbon emissions in the countries of the Americas.

In two separate bags, learners mix water with Epsom salts and detergent.

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this activity, learners explore the different heating properties of soil and water.

In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.

In this activity, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to explore the interplay of motion and sound.

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.
