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.

Handheld Water Bottle Rocket & Launcher
Source Institutions
In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

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.

Reflective Solar Cooker
Source Institutions
In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.

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

Water Rocket Launch
Source Institutions
In this activity, learners explore rocketry and the principals of space flight.

The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

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.

Equatorial Sundial
Source Institutions
In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

Telescopes as Time Machines
Source Institutions
This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

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.

Build Your Own Solar Oven
Source Institutions
Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

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.

Standing in the Shadow of Earth
Source Institutions
This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

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.
