In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.

In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

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

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this outdoor activity, learners release a portion of a lawn from human control—no mowing, no watering, no weeding, no pest control—and then investigate the changes that result over several weeks.

In this outdoor science/art activity, learners investigate spider webs by using string to create their own spider webs.

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv

This activity (on page 2 of the PDF under SciGirls Activity: Malformed Frogs) is a full inquiry investigation into using indicator species to assess the health of an environment.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this data collection activity about crabs, learners use data from the Virginia Institute of Marine Science (VIMS) trawl survey to determine the areas of the Chesapeake Bay that are being used by bl
