In this activity, learners observe and describe the physical and behavioral characteristics of insects, including crickets.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.

In this creative activity, learners will find out what makes an insect an insect by studying examples of insect adaptations and by examining why there are so many different types of insects.

In this activity, learners explore the "nuts and bolts" of gene chips.

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 construct a model of DNA to better understand the structure of DNA and protein synthesis.

In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

In this hands-on activity, learners investigate the functional design of leaves on a tree.

In this activity, learners create a three-dimensional sculpture while examining the characteristics of fish.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this activity, learners will create their own coral polyps - the basis for a coral reef.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.

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

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this activity about human anatomy (page 16 of PDF), learners construct a model arm and discover how muscles and bones work together to achieve efficient movement.
