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.

Shadow Play
Source Institutions
In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

Pop Rockets
Source Institutions
Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

Water Exploration Station
Source Institutions
In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

Garden Poles
Source Institutions
In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

COSI's Bubble Recipe
Source Institutions
Everybody loves bubbles, and this is the best bubble recipe ever!

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

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.

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.

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.

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.
