In this fun hands-on activity learners explore a simple machine: the lever. What happens to a load when you multiply the length of a lever? Find out here!

Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

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

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

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

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

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

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