In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity, learners examine ways that Native Americans of the Southwest express their relationship with nature through art.

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 activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this activity, learners observe mixtures of sand samples glued to note cards, and consider how sand can differ in size, shape, and color, and where it comes from.

In this activity, learners simulate a wolf and its habitat and observe what happens when the limiting factors change over time.

In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

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

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

In this activity, some learners pretend to be wolves, while the other learners pretend to be the prey of the wolf. The goal of the simulation is to have the wolves work together to survive.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

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

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

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

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.

In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

Learners will understand the relationship between climate change and sea-level rise.

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.
