If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.

In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.

In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

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, which requires adult supervision, learners get to explore the awesome power of chemistry.

In this activity, learners will discover why there are holes in bread.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

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?

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

Many common household cleaners are antimicrobials.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
