In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.

In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.

Learn about chemical reactions by making a Bubble Bomb, a plastic bag you can pop with the power of fizz.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

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 "Sid the Science Kid" activity from Episode 109: The Perfect Pancake, learners make applesauce to explore irreversible change.

This activity uses turmeric, a common spice in curry, as an indicator for acidity and basicity. Turmeric is yellow in acid and neutral substances, but turns bright red with bases.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

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.

Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

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.

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

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

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
