In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this activity (23rd on the page), learners conduct an experiment to examine memory and learning.

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.

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.

In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th

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, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this activity, which requires adult supervision, learners get to explore the awesome power of chemistry.

Many people get water from a source deep underground, called groundwater.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

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 chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.
