In this activity, learners create a "mini sky" in a glass of water in a dark room.

Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.

Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

Learners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of water.

Create a simple dual pendulum and get them to swing in identical ways. This is a simple, low cost, activity produced by the Exploratorium.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

In this activity, learners will test soil content using their sample, some water and a container that seals.

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

In this activity, learners discover a trick to release the air out of a balloon without popping it.

In this online game, learners must keep their snowboarding racer in the middle of the course without veering off track or hitting obstacles.

Conduct a simple experiment to explore how temperature changes can make things expand or contract.

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.

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.
