Ants
Source Institutions
In this outdoor activity, learners investigate ant behavior by testing ant feeding reactions to different types of food.

Night Eyes
Source Institutions
In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

Regolith Formation
Source Institutions
In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

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).

Quick Frozen Critters
Source Institutions
In this activity, learners play an active version of freeze tag based on predator/prey relationships.

Crawdad Grab
Source Institutions
In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

Silent Stalking
Source Institutions
In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.

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.

Acorns
Source Institutions
In this outdoor game, learners play the roles of gray or red squirrels gathering and storing a supply of food in "fall" and recovering enough of them to survive the "winter." Learners carry bags repre

Sun Prints
Source Institutions
This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

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

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

Stargazing
Source Institutions
In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

Jay Play
Source Institutions
In this outdoor activity, learners find out the color of food that jays prefer and then try to change the birds' preference by altering the taste of the food with salt.

Fly a Leaf
Source Institutions
In this outdoor, windy day activity, learners "fly" and race leaves along a line to discover which types of leaves catch the most wind. Which leaves are the best fliers? Why?
Soil Secrets
Source Institutions
In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.

Junk-in-the-Box
Source Institutions
In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.

Seed Dispersal
Source Institutions
In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

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.

Saldo Island: An Unfair Game
Source Institutions
In this environmental science activity about biodiversity, learners play a game to discover the effects of non-native species on an ecosystem.
