In this outdoor activity/field trip, learners locate and study plants and animals in several freshwater pond habitats.

In this outdoor activity/field trip, learners investigate the special shapes, holding structures and holding behaviors that real organisms use in streams, rivers, creeks or coast intertidal zones to a

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 outdoor/indoor activity, learners collect ants and dirt to create an ant farm in a cup that they can observe over time.

Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

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.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.

Plants need nutrients to grow. This is why we apply fertilizers to grass and food crops. In this activity, learners will explore how fertilizers can affect lakes and other bodies of water.

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.

Millions of organisms can live in and around a body of water.

In this activity, learners make a model of a one-way heart valve to investigate how a heart controls the direction of blood flow.

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

Your heart pumps blood throughout your body in one direction, around in a loop. In this activity, learners will make a model of one type of heart chamber called a ventricle.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.
