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

Make a Snake String & Snake Survey
Source Institutions
In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.

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

Make Your Own Ant Farm
Source Institutions
In this outdoor/indoor activity, learners collect ants and dirt to create an ant farm in a cup that they can observe over time.

Population Game
Source Institutions
In this outdoor game, learners simulate a herd of deer trying to survive in an area called the "home range." Learners explore the concept of "carrying capacity"—what size population of an organism can

Bird Feeder
Source Institutions
In this outdoor activity, learners construct bird feeders and set them up at to investigate bird behavior for one or two weeks. Multiple feeder designs are suggested.
Splitting White Light
Source Institutions
In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

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

Bird Nests
Source Institutions
In this outdoor activity, learners build bird nests and place them in the activity area, then play the role of naturalists as they try to locate each other's nests.

Food Chain Game
Source Institutions
In this outdoor game, learners role play populations linked in a food chain.

What Do Birds Do?
Source Institutions
This activity (located on page 3 of the PDF) is a full inquiry investigation into bird behaviors.

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.

Tree Trunk Diameter to Branch Height Relationship
Source Institutions
In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

Make Pooter
Source Institutions
In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

Water Breathers
Source Institutions
In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.

Web Weavers
Source Institutions
In this outdoor science/art activity, learners investigate spider webs by using string to create their own spider webs.

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.

Bird Watching
Source Institutions
In this activity, learners will observe birds in their backyard or local park. They will attempt to find common Ohio birds and will look for bird behaviors just like an ornithologist.

A Better Fly Trap
Source Institutions
In this activity, learners observe fly behavior and then build a flytrap.

Base Station Walk-Back
Source Institutions
In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.
