In this activity, learners use chemistry to produce weathered "antiqued" paper with burned edges. Learners first soak white paper in coffee and then apply a charring solution of ammonium chloride.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.

In this craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

This is an online game about stopping distance. Learners choose one of three vehicles and one of three speeds.

Can you deceive your eyes? When your eyes work normally, you see a nice 3 dimensional picture, but what happens when each eye sees something different?

This is a quick and simple demonstration about reflexes (second activity on the page).

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

Spin in an office chair holding milk jugs! Plus, learn physics. Very fun (but stay safe) activity from the Exploratorium Science Snacks series.

In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes.

A simple, yet fun activity that lets learners find the center of balance of a ruler (or any long thin object). Developed by the Exploratorium and no assembly needed.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.

In this activity, learners make critters out of recyclables and apply the rules of mathematics to solve genetics problems.

In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.

This is an activity where learners will discover what types and how many insects live in their own backyard.

In this activity, learners balance chemical equations and discover the law of conservation of mass. Learners use coins to model molecules to balance the equations.

In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

In this activity, learners explore a bucket of sand and beach objects.
