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 add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

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 will experiment with catalysts to create an at-home version of elephant toothpaste.

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

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

In this investigation of reaction kinetics, learners alter the amount of iodate solution mixed with the same amount of starch solution.

In this activity, young learners will experiment with a basic chemical reaction and observe what happens when gas gets trapped! Activity includes step-by-step instructions, safety notes and more.

Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.

In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

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 activity, learners discover that there is space between molecules even in a cup "full" of water. They first fill a cup with marbles, and then add sand to fill the gaps between the marbles.

In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.
