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.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

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 matching game, learners study the limits of life on Earth to see what other places in the solar system might sustain microbial life.

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

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

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

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

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.

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.

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

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
