In this archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.

In this activity, learners stain fabrics--on purpose!

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

In this activity, learners investigate feeding relationships. Learners complete a food web and then make a mobile to represent a food chain.

In this activity, learners create an origami model of DNA, demonstrating its double helix structure.

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

In this activity, learners overlap the three primary colors to see how all other colors are made.

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 activity, learners will collect, dry and press seaweed over the course of four days in a similar way that artists/crafters press flowers.

In this craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

Learners construct a bracelet containing two strands of beads, which represents a double strand of DNA that codes for a gene. They match beads to the bases in a section of a chimp's DNA code.

Coins are everyday objects which tell a lot about the people who use them.

In this activity, learners explore the question "What is paper?" Learners discover the processes and materials required to make paper while experimenting with different recycled fibers and tools.

String Thing is an interactive online game in which learners change a virtual string's tension, length, and gauge to create different musical pitches.

In this activity (p.25 of PDF), learners investigate spores. Mushrooms produce millions of spores which are equivalent to the seeds of plants but without the massive food reserves.

In this activity (p.24 of PDF), learners make paper with fungi. Learners discover that paper is basically a flat mat of fibers.

In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.
