In this activity, learners will exercise their imaginations and artistic skills. Appropriate for all ages, learners will create unique pieces to jumpstart storytelling sessions.

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

In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners will compare predicted and observed tides using data from The National Oceanic and Atmospheric Administration(NOAA).

In this activity (page 1 of the PDF under SciGirls Activity: Rabbits), learners will visit a zoo, aquarium, or pet store to view a variety of fish.

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

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 outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

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

In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

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.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

In this activity, learners collect worms and then observe how they move.

In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.
