Water Drop Races
Source Institutions
In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

Feather Rockets
Source Institutions
In this activity, learners will make and launch feather rockets. Lerners will use science process skils such as making predictions and measuring while launching the rockets.

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

Make Your Own Pendulum
Source Institutions
In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

No Pressure
Source Institutions
In this activity, learners observe what would happen to their bodies if they went to outer space without a space suit.

Mid-Air Maneuver: Skateboard Science
Source Institutions
To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

Make and Fly a Helicopter
Source Institutions
Learners follow the template to build and fly a paper helicopter.
Coat Hanger Chimes
Source Institutions
In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.

¡Paracaídas!
Source Institutions
En esta actividad, los participantes explorarán las fuerzas de gravedad y la resistencia al aire usando paracaídas.

Decibel Cannon
Source Institutions
In this activity, learners will construct an air cannon as a model for the human ear.

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.

Holding Charge
Source Institutions
In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.

Clues About Clouds
Source Institutions
In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

The Straw Flute
Source Institutions
In this is activity about sound and vibration, learners create their own 'flutes' with drinking straws, then investigate how changing the length of the straw affects the sounds that are produced.

Twist and Spout
Source Institutions
In this activity, learners make their own "tornado" using two soda bottles and water.

Frosty Glasses
Source Institutions
In this activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.

Engineer an Aeolipile
Source Institutions
In this engineering design challenge, learners build an air-powered spinning machine.

Which Parachute
Source Institutions
In this activity, learners will engineer three different parachutes to test how well each one works.

Balloon Inside a Bottle
Source Institutions
In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

Drag: Parachute from the Stratosphere
Source Institutions
This is an online game recreating the longest ever (at that point in time) freefall jump by Air Force Captain Joe Kittinger.
