In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

In this activity, learners are asked to examine the differences between two materials in a pair.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners use a chemical reaction to visualize where moisture forms on the body.

The goal of this Star Wars activity is to design and build a balancing device to help an Ewok escape the Imperial Forces by sliding down a tightrope to safety.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

In this series of exercises, learners predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed wh

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this chemistry challenge, learners systematically investigate which combination of four solutions produces a deep red color.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

In this activity, learners explore how watermills have helped harness energy from water through the ages.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.
