How Do We Convert Mechanical Energy into Electrical Energy?
Source Institutions
In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

Sky Glider Challenge
Source Institutions
In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

Thrill Ride
Source Institutions
In this activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.

What is Energy?
Source Institutions
In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

Wind Works!
Source Institutions
Learners will build and experiment with their own windmills made from simple household materials.

Masses & Springs
Source Institutions
In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

The Ballistic Pendulum
Source Institutions
In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.

Confetti Launcher
Source Institutions
Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.

Paper Airplanes
Source Institutions
In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

Homemade Rube Goldberg Machine
Source Institutions
In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

Spool Racer
Source Institutions
In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

Rubber Band Car
Source Institutions
In this design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.

Take an Egg for a Spin
Source Institutions
This is an activity about friction as well as kinetic and potential energy.

Roller Coasters
Source Institutions
In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.

Rolling Returns
Source Institutions
In this activity, learners build a special rolling can that returns back to you when you push it forward. Use this activity to demonstrate the transfer of energy between kinetic and potential energy.

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

Downhill Race
Source Institutions
In this activity, learners explore how two cylinders that look the same may roll down a ramp at different rates.

Bouncing Balls
Source Institutions
When baseball was in its infancy, the ball had plenty of bounce. Today's baseball may not seem to have bounce to it at all; if you drop a ball on the field it won't bounce back.
Windmills
Source Institutions
In this physics activity (page 8-9 of the PDF), learners will explore wind energy. They will build their own windmill and see how energy from wind can be converted into a useable form.

Rubber Band Boat
Source Institutions
In this activity, learners build styrofoam boats powered by twisted rubber bands.
