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 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 (on page 1 of the PDF under SciGirls Activity: Earthquakes), learners will use a magnifier to carefully examine samples of sand from different locations.

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).

Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

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, learners use simple materials to build their own compass.

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 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.

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.

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.
