Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

Learners use a simple process to extract DNA from strawberries.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

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.

Learners design their own experiment to investigate how pollution diffuses through ground material.

In this experiment, learners isolate Deoxyribonucleic Acid (DNA) from onion cells using a simple extraction procedure.

In this experiment, learners will explore whether increased carbon dioxide makes our oceans more basic or more acidic.

In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.

Our bodies defend themselves in many different ways to prevent us from getting sick.
