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.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this genetics activity, learners discover how to extract DNA from green split peas.

In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

In this science trick, learners get an egg to stand-up on its long-axis vertical to a table's top.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this data analysis activity, learners use data collected by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to study Chilean sea bass populations.

In this activity, learners will explore the chemistry of cooking. They will learn about--and observe--the Maillard Reaction as they make their own browned butter.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

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

In this activity, learners use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

In this activity, learners follow step-by-step instructions to build a gel electrophoresis chamber using inexpensive materials from local hardware and electronic stores.
