Algae String
Who needs boring old plastic? Get creative and use simple at-home chemistry to transform natural materials from living seaweed into flexible, colorful string! What will you create?
Cabbage Inks
Can you make color-changing paint from a simple cabbage? No doubt, sauerkraut. This activity from the scientists behind our BioTinkering Lab brings together biology, chemistry and art for an experience that is all science, and a little bit of magic.
Making with Microbes
Ever wanted to grow your own paper or plastic? Or create leather that doesn’t use animals? All these can be done at home by collaborating with microbes — tiny microscopic organisms — to grow a custom biomaterial.
Life Science Lessons
These lessons explore the natural world of animals, plants and even living things we can’t see, like bacteria! Your learners will engage more deeply with life sciences when you add real-world layers like hands-on building, engineering design challenges, or computer programming.
