In this activity, learners use models of fossilized dinosaur teeth to understand how dinosaur teeth were used.

This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.

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

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

In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

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

In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish.

In this activity, learners touch and observe skulls of sharks and rays to learn about their diversity (over 400 species of sharks alone!).

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.

In this classic activity, learners investigate natural selection by becoming birds foraging for food on an island.

This activity (on page 3 of the PDF under GPS: Biodiversity Activity) is a full inquiry investigation into biodiversity.

In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal

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

In this outdoor, sensory activity, learners role play as animals trying to identify their "family's" scent and locate their "territory." Learners mark their territories and sniff out other territories

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this activity (page 2 of PDF under GPS: Alligator Habitat Activity), learners will study the adaptations different fish species have developed to survive in their habitats.

Birds' beaks are designed to allow birds to get the most of whatever food they need. In this activity, learners get an idea of how different beak shapes suit different food sources.

In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an
