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

Biological Succession in a Microecosystem
Source Institutions
This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

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.

Life in the Sidewalk Cracks
Source Institutions
In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.

Pollinator Play
Source Institutions
In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.

Discovery Time: Bugs
Source Institutions
In this activity, young learners (2 years and up) explore the world of insects and other "bugs" by Making a "bug hotel" with recycled objects.

Cactus Wheel
Source Institutions
In this outdoor activity/field trip, learners explore the concept of population density.

The Blue Crab's Chesapeake Journey
Source Institutions
In this data collection activity about crabs, learners use data from the Virginia Institute of Marine Science (VIMS) trawl survey to determine the areas of the Chesapeake Bay that are being used by bl

The Self-Watering Terrarium
Source Institutions
In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

Sticklers
Source Institutions
In this outdoor simulation game, learners search for pretend animals called "sticklers" to determine and map where they live (habitat) and how spread out they are in that area (distribution).

Water Walk
Source Institutions
Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

Bugs, Worms & Others
Source Institutions
In this creative outdoor activity, learners invent populations of make-believe organisms and then investigate real populations living in the activity site.

Sensory Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

An Interdisciplinary Deer and Human Population Study
Source Institutions
This activity helps the learner answer the question: "What environmental problems arise due to animal and human overpopulation and what might need to be done to combat these problems?" Learners play a

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

Design-a-Fish
Source Institutions
In this science and language arts activity, learners study fish anatomy and make their very own 3D paper fish.

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.
