In this activity, learners examine how brine shrimp populations can survive in some of the harshest environments.

In this activity, learners work in small groups to match various marine animals with their different environments.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

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 order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s

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

This is an outdoor activity designed to demonstrate evolution of feeding behavior in flocking, schooling or herding animals that maximizes allocation of food resources and enhances survival.

In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

In this activity, learners simulate a wolf and its habitat and observe what happens when the limiting factors change over time.

In this activity, some learners pretend to be wolves, while the other learners pretend to be the prey of the wolf. The goal of the simulation is to have the wolves work together to survive.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

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

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 (p.14-15 of PDF), learners discover the concepts of competition and limiting factors as they relate to plant and animal communities.

In this outdoor activity and animal-role-play game, learners discover and uncover the hidden world of "cryptozoa"—organisms such as spiders, salamanders and slugs that live under objects, like rocks a

In this activity, learners play an active version of freeze tag based on predator/prey relationships.

In this activity/demonstration, learners explore pollen and how insects and animals transport pollen. Learners investigate and compare wind and animal pollination.
