In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.

In this activity, learners build small animated toys that move.

In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.

In this activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.

In this environmental activity (page 16 of the PDF), learners will calculate the amount of energy they save by recycling paper, plastic, glass, and aluminum materials over the span of a week.

This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

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

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

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.
