Cupcake Delivery
Source Institutions
In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

Magnetic Spinner & Compass
Source Institutions
Learners use shop tools and various materials to construct a magnetic spinner and a compass.

Marble Game
Source Institutions
In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

Hovercraft
Source Institutions
In this activity, learners make plates levitate! Learners build "hovercrafts" using simple materials to explore friction and motion.

Egg Drop Trick
Source Institutions
In this activity, learners explore the real science behind an egg drop "magic trick." Learners will wow their families by harnessing gravity, friction and motion to make 3 eggs fall off of their pedes

Jumping Beans
Source Institutions
In this physics activity (page 3 of the PDF), learners will explore the concept of static electricity.

Balloon Hovercraft
Source Institutions
In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

Echo Base Bobsleds
Source Institutions
The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

Rubber Band Racer
Source Institutions
In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

Coupled Resonant Pendulums
Source Institutions
In this activity, learners discover that two pendulums suspended from a common support will swing back and forth in intriguing patterns, if the support allows the motion of one pendulum to influence t

A Spray Spree
Source Institutions
In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.

Marshmallow Puff Tube
Source Institutions
In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

Airboat
Source Institutions
In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

Balls and Ramps
Source Institutions
In this activity, learners use simple, everyday materials to experiment with balls and ramps.

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.

Uncanny Motion
Source Institutions
In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

Propeller-Powered Car
Source Institutions
In this activity, learners construct cars that are powered by hand-made, electric propellers.

Balloon Car
Source Institutions
Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.

Screaming String Thing
Source Institutions
In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.

Raceways
Source Institutions
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.
