Beating Gravity
The ExploratoriumAdd to list DetailsIn this demonstration, learners watch as a device drops a ball into a cup without touching the ball or cup, even though the ball and cup are virtually side-by-side. Specifically, this device...
Marshmallow Puff Tube
The ExploratoriumAdd to list DetailsIn this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder. The result is spectacular, and the process provides a great...
Magnetic Free Fall
The ExploratoriumAdd to list DetailsIn this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law. Learners will observe as gravitational and magnetic forces act on two falling objects to...
Springs and Stomachs
The ExploratoriumAdd to list DetailsIn this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp...
Paper Tape Motion Timer
The ExploratoriumAdd to list DetailsIn this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.). The device produces a record of...
Rubber Band newton Scale
The ExploratoriumAdd to list DetailsIn this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N). Learners will gain an understanding of and familiarity...
Newton's Laws Demonstrations
The ExploratoriumAdd to list DetailsIn this collection of demonstrations, learners explore Newton's Laws of Motion. These seventeen quick activities investigate air resistance, acceleration, terminal velocity, inertia, action...
Falling Feather
The ExploratoriumAdd to list DetailsIn this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both...
Balancing Ball: Suspend a ball in a stream of air
The ExploratoriumAdd to list DetailsBalance a ball in the air with a hair dryer! This Exploratorium produced activity shows learners concepts like lift and air streams. You can try many different angles, speeds, and ball types.
Free-Fall Bottles & Tubes
The ExploratoriumAdd to list DetailsIn this physics activity, learners conduct two experiments to explore free-falling. In the first experiment, water-filled plastic bottles with holes in them spurt water under normal conditions, but...
