Animal Diversity
Source Institutions
In this outdoor activity, learners find, count and compare as many different kinds of animals as they can find in two different areas: a managed lawn and a weedy area.
Invent an Insect
Source Institutions
In this creative activity, learners will find out what makes an insect an insect by studying examples of insect adaptations and by examining why there are so many different types of insects.
Invent an Animal
Source Institutions
In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.
Food Chains and Webs
Source Institutions
In this activity, learners investigate feeding relationships. Learners complete a food web and then make a mobile to represent a food chain.
Measuring Biodiversity
Source Institutions
Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.
Hunting Minibeasts
Source Institutions
In this activity (p.6-10 of PDF), learners use different methods for hunting minibeasts (bugs). Learners can either make traps or simply look for minibeasts under stones and logs.
Corals and Chemistry
Source Institutions
In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin
What's in the Water?: Biotic and Abiotic Elements in Aquatic Ecosystems
Source Institutions
In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.
Invent an Insect
Source Institutions
In this creative activity, learners will find out what makes an insect an insect by studying examples of insect adaptations and by examining why there are so many different types of insects.
Don't Stop for Hitchhikers
Source Institutions
In this activity, learners role-play the part of lake inhabitants and the aquatic exotics who displace the native species.
Wolf Survival
Source Institutions
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.
Introduction to Ocean Zones
Source Institutions
In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.
Conservation Island
Source Institutions
In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.
Scram or Freeze
Source Institutions
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
Lupine and Butterflies
Source Institutions
In this two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.
Litter Critters
Source Institutions
In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.
Create a Mangrove Tree
Source Institutions
In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.
Can Fishing
Source Institutions
In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.
Amphipods: More than Mud
Source Institutions
In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.
Mystery of the Disappearing Cottonwoods
Source Institutions
Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
