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

In this physics activity, learners construct a small-scale version of a classic carnival game.

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

In this activity, learners use raisins and seltzer water to understand why waves don’t move objects forward. Learners conduct two simple experiments to understand the circular movement of waves.

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 activity, learners create a toy that demonstrates the First Law of Thermodynamics or the Law of Conservation of Energy.

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

In this activity, learners build an old-fashioned paddle boat out of simple materials.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

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.

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

Learners build a wind turbine and test it to see how much energy is created.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this online game, learners must purchase power plants for their city.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.

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