Water Rocket Launch
Source Institutions
In this activity, learners explore rocketry and the principals of space flight.
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.
Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.
Tree Tally
Source Institutions
In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.
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.
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.
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!
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.
Stomp Rocket
Source Institutions
In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.
Life in the Sidewalk Cracks
Source Institutions
In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.
Pop! Rocket Launcher
Source Institutions
In this activity, learners construct a simple air pressure launcher for paper rockets.
Salt Water Revival
Source Institutions
In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.
Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.
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
What Do Birds Do?
Source Institutions
This activity (located on page 3 of the PDF) is a full inquiry investigation into bird behaviors.
Can Energy be Created or Destroyed?
Source Institutions
In this activity, learners explore conservation of energy by experimenting with a solar cell light device.
Personal Pinhole Theater
Source Institutions
Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!
