In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

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

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.

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.

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 activity, learners make a model of a beehive using simple materials.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this outdoor activity, learners build bird nests and place them in the activity area, then play the role of naturalists as they try to locate each other's nests.

In this activity (Lesson 1), learners work in groups to create tide simulations.

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

In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

In this activity (on pages 29-35), learners examine water pollution and filtration.

In this outdoor activity, learners design devices that will catch prey or gather plants.

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.
