Avalanche
Source Institutions
In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

Newton's Laws Demonstrations
Source Institutions
In this collection of demonstrations, learners explore Newton's Laws of Motion.

Free-Fall Bottles & Tubes
Source Institutions
In this physics activity, learners conduct two experiments to explore free-falling.

Eddy Currents
Source Institutions
In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

Beating Gravity
Source Institutions
In 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.

Falling Feather
Source Institutions
In 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 weights fall

Over the Hill
Source Institutions
In this physics activity, learners construct a small-scale version of a classic carnival game.

Pendulum Snake
Source Institutions
In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums

A Simple Escapement Mechanism
Source Institutions
In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

Springs and Stomachs
Source Institutions
In 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-poi

Rubber Band newton Scale
Source Institutions
In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).
