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.

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

In this activity, learners work in groups to create a time line representing significant moments in their lives.

In this activity, learners use simple materials to build their own compass.

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 activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

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

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.

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

In this activity, learners will engineer three different parachutes to test how well each one works.

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

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

¡En esta tira cómica, Mateo y Cientina son detectives! Ellos usan sus destrezas investigativas para identificar de dónde provinieron algunas muestras de arena.

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.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.
