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.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

This demonstration activity models how Venus appears from Earth.

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

A simple, yet fun activity that lets learners find the center of balance of a ruler (or any long thin object). Developed by the Exploratorium and no assembly needed.
