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.

Beachcombing
Source Institutions
In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.

Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

What Lives Here
Source Institutions
In this outdoor activity/field trip, learners explore an aquatic site such as a pond, lake, stream, river or seashore to find and investigate plants and animals that live in water.

Food Grab

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

Hopper Herding
Source Institutions
In this outdoor activity and game, learners roundup a "herd" of hopping insects and find out how many different kinds or species are in their herd.

Sound Off!
Source Institutions
This activity includes several games about animal sounds. Using their sense of hearing and communicating with various kinds of noisemakers, learners role-play predator and prey.

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

Logs to Soil
Source Institutions
In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.

Trail Construction
Source Institutions
In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

For the Birds
Source Institutions
In this outdoor activity, learners turn the fun of feeding wild birds into an investigation of bird behavior.

Wintergreen
Source Institutions
In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
