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

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

In this activity, learners investigate the basic crystal structures that metal atoms form.

In this activity, learners use an origami template to design eight amino acids. Learners configure the amino acids to form a protein. Use this activity to introduce proteins and amino acids.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

No glue is needed for learners of any age to become marshmallow architects or engineers.

This activity introduces learners to the structure and properties of carbon nanotubes.
