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 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 physics activity (page 10 of the PDF), learners will make a can that will roll back after it has been rolled away to observe the interactions of kinetic and potential energy.

Learners are given mysterious white powders and have to determine their identity with chemical tests.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

In this physics activity, learners will explore the concept of buoyancy, especially as it relates to density.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.

Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

Learners use a simple process to extract DNA from strawberries.

In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

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.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

In this activity about friction and gravity (page seven of the pdf), learners use toy racing cars to explore how the two forces affect the motion of objects.
