In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

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

In this activity (page 12), learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a comb

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.

This neuroscience activity introduces learners to how messages are sent and received by neurons. Learners use modeling clay and pipe cleaners to build model neurons.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.

In this activity, learners construct a 3-D paper model depicting how histone, acetyl and methyl molecules control access to DNA and affect gene DNA expression.

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.

In this activity, learners explore how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a combined unit.

In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
