Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

Build a Lung
Source Institutions
Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

Static Electricity
Source Institutions
In this activity, learners will explore ways static electricity interacts with the surroundings of an object. The activity has step-by-step instructions in English and Navajo.

Drawing Conclusions
Source Institutions
In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

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.

Aluminum-Air Battery: Foiled again!
Source Institutions
Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

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.

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.

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

The Power of Words
Source Institutions
This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

Engineer an Octopus Suction Pad
Source Institutions
In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

Metal Noise Maker
Source Institutions
In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.
Parachute Design
Source Institutions
In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.

On the Fringe (formerly Bridge Light)
Source Institutions
In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.
Musical Coathanger
Source Institutions
In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.

Cylindrical Wing
Source Institutions
In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

Lichen Looking
Source Institutions
In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.
