In this activity, learners use Styrofoam to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

In this activity, learners use coverslips to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

In this group or individual activity, learners are encouraged to watch birds near home or school—possibly where birds are nesting in a tree, pecking in a park, feeding from a feeder, or flying through

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

The purpose of this lab is to recognize that the answers to some of society's industrial challenges may lie right in our own backyards.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

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 find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

This detailed lesson plan for a field trip to Canyonlands National Park in Utah (page 32 of pdf) teaches students about the habitat of bighorn sheep.

In this laboratory activity, learners use a simple procedure to bait oomycetes from water and/ or soil and then examine these fungus-like organisms with the microscope to see how they look.

In this activity (page 2 of PDF under GPS: Garbology Activity), learners will prepare sheets of homemade recycled paper from several different source pulps.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.

In this activity, learners will create a soil profile in a bottle. They will learn about the organic and inorganic matter found in soil and observe as it separates into layers in the bottle.

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.

In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.
