In this activity, learners will simulate the interactions between a predator population of gray wolves and a prey population of deer in a forest.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this hands-on botany activity, learners sprout vegetables in film canisters.

In this activity, learners pretend that they are orcas and search for their "pods" using Morse code.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this activity, learners make a camouflaged butterfly to hide outside for others to find.

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.

In this matching game, learners study the limits of life on Earth to see what other places in the solar system might sustain microbial life.

This is an activity to do when there is a solar eclipse!

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 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 (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.

This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.

In this activity, learners construct a home-made journal with simple, everyday materials.

In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible
