In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

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.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

In this activity, learners investigate passive solar building design with a focus solely on heating.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

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

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.

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.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

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

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

In this activity, learners determine whether thermal energy can be used for work.

This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.

Learners attach an egg to a rubber-band bungee cord and drop the egg.
