In this activity, learners investigate feeding relationships. Learners complete a food web and then make a mobile to represent a food chain.

In this activity, learners make homemade journals featuring seashell rubbings. First, learners transfer the texture of a seashell onto a piece of paper using a crayon.

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

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 activity, learners explore why animals, specifically dinosaurs, live in families.

In this simulation activity, learners will raise a pack of wolves under ten different conditions: without human interference and with human interference.

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

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 build one or more edible coral polyps and place them together to form a colony.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

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

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 (page 5 of pdf), learners explore the relationships between the shape and structure of a shark's teeth and the food it eats, and then create their own shark tooth from clay.

In this outdoor, mystery-solving activity, learners work like detectives, gathering evidence to identify the culprits that are attacking plants.

In this outdoor fall activity, learners find out what living in or under a layer of leaves is like.

In this activity (p.5-6 of PDF), learners investigate natural selection. Learners discover that natural selection, which takes place over decades, can lead to altered populations within a species.

In this activity, learners play a game to simulate the food chain.
