In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

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

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, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

Using simple, inexpensive items, learners build and test submarine models.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.

In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

In this activity, learners investigate the food, water, and space needs of common livestock animals.
