In this activity, learners make a device called a phenakistoscope, which displays a continuously looping animation consisting of images drawn onto a spinning disc.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

Visitors observe a tray holding a crystal-covered brick. The crystals were created by evaporation of a solution containing liquid bluing, ammonia, and salt.

In this construction activity, students use a 2-liter bottle to build a fly trap.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

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.

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

In this activity, learners will experiment with catalysts to create an at-home version of elephant toothpaste.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

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

Our bodies defend themselves in many different ways to prevent us from getting sick.

Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.

In two separate bags, learners mix water with Epsom salts and detergent.

In this activity, learners build a bird feeder or feeders to attract birds for observation.

In this activity, learners will exercise their imaginations and artistic skills. Appropriate for all ages, learners will create unique pieces to jumpstart storytelling sessions.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

Make impact craters with marbles (or rocks or washers) in a container of flour. Find out what you can learn about your "comets" by the craters they make.

In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.
