In this classic activity, learners investigate natural selection by becoming birds foraging for food on an island.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

In this outdoor activity that can be combined with a hike, learners try to match a "mystery community" by shaking animals out of different trees and shrubs.

In this plant science activity, learners role play as vegetables and weeds competing for nutrients.

In this interactive board game, learners "hire" different types of scientists to help canine character Ruff Ruffman solve unusual problems.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this playful activity, learners explore the structure of the cell—the basic unit of every living organism—by creating a model of cell structures using soap bubbles, and by examining a slice of onio

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.

In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.

This is a tape and glue activity in which learners make binoculars that they can decorate and then use to go bird watching.

What does it mean to be alive? Is a cactus alive? Is a seed alive? Is the air we breathe alive? What are the necessary characteristics?

In this open-ended multicultural lab activity, learners investigate the effectiveness of herbal remedies.

In this game, learners match descriptions of marine debris (shoes, batteries, paper towels, etc.) to images of these items.

In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.

In this activity, learners observe fly behavior and then build a flytrap.

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 will examine a variety of seeds, describe them, and determine how they are dispersed.

In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.
