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 explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.
