In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

Many people get water from a source deep underground, called groundwater.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

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

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.

In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

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.

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 outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

In this archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

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