Water Holes to Mini-Ponds
Source Institutions
Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

Isopods
Source Institutions
In this outdoor activity, learners dig for and collect isopods (sometimes known as "roly-poly bugs" or "potato bugs" and other names).

The Scoop on Habitat
Source Institutions
Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

Lichen Looking
Source Institutions
In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.

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.

Counting With Quadrants
Source Institutions
Millions of organisms can live in and around a body of water.

Invent an Animal
Source Institutions
In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

Rock Pioneers
Source Institutions
In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

Attention!
Source Institutions
In this outdoor art/environmental activity, learners create designs that will attract attention to animals and plants in particular habitats, and then test whether their designs attracted the "right"

Plant Hunt
Source Institutions
In this outdoor activity and game, learners collect and sort leaf samples to determine how many types of plants grow in the activity site.

Envirolopes
Source Institutions
In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

Variation Game
Source Institutions
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.

Animals in a Grassland
Source Institutions
In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.

Snug as a Bug
Source Institutions
In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

Clam Hooping
Source Institutions
In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

Tree Tally
Source Institutions
In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.

Roots and Shoots
Source Institutions
In this outdoor activity, learners discover that plants aren't just shoots (stem, branches, leaves, and flowers) growing above ground, but contain plenty of roots growing underground—more than half th

Beach Zonation
Source Institutions
In this outdoor, ocean-side activity, learners investigate the distribution of organisms in the upper region of the intertidal zone.

Plant Patterns
Source Institutions
In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

Elephant Foot
Source Institutions
Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.
