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

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

Learners write an invisible message using lemon juice on a piece of paper. They then develop the message by soaking the paper in a dilute iodine solution.

In this experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.

In this activity, learners will experiment with catalysts to create an at-home version of elephant toothpaste.

In this activity, learners explore materials through paper chromatography.

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

In this activity, learners test what happens when they put baking power on different frozen liquids.

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

In two separate bags, learners mix water with Epsom salts and detergent.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this chemistry activity (page 1 of the PDF), learners will observe a physical change.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

In this challenge, learners figure out how to make a juice stain disappear.

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

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).

In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.
