In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this design challenge, learners will use microbes to design and grow a custom biomaterial at home and make something creative with it.

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.

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.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity, learners explore a bucket of sand and beach objects.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

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

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
