In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

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

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

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

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

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

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 look at and touch marine animal skulls to compare them and think about what they eat.

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 culinary activity, learners use multiple senses (sight, smell, touch, and taste!) to explore real seaweed samples.

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 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

In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.

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

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.

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

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

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).

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.
