In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

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

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

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

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

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.

In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.
