This lesson focuses on graphene and its electrical properties and applications.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In this activity, learners will build a stomp-powered launcher to blast off paper rockets they design. Materials can be found at a local hardware store or you may already have them at home.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

In this activity, learners create secret messages using a candle. Learners discover that watercolor paint is attracted to some materials, like paper fibers, but not others, like oil.

Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.

In this activity, learners concoct some stretchy green goo called Gak. This activity will introduce learners to polymers, chemical reactions, and how scientists invent new materials.

In this activity, learners investigate the movement caused by dispersion. Learners discover that dispersion is the random movement of objects.

This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d

In this activity, learners investigate how some butterfly wings get their color.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

In this activity, learners investigate the properties of graphene and graphite.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this activity, learners will explore how product barcodes are scanned accurately and be able to "guess" the last number in a 13 digit barcode correctly every time.

In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static

Build a house you can fit inside, using cardboard tubes.
