How the Mushroom Got Its Spots
Source Institutions
In this activity (p.26 of PDF), learners discover why mushrooms have spots. Learners use a balloon, toilet paper, and water to simulate what happens as mushrooms grow.

Soggy Science, Shaken Beans
Source Institutions
Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

Trail Impact Study
Source Institutions
In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

Frog Olympics
Source Institutions
Did you know that a bullfrog can jump a distance of 10 times its body length? Learn more about nature's most acrobatic amphibian, the frog, through this set of short, hands-on activities.

Follow the Scent
Source Institutions
In this outdoor, sensory activity, learners role play as animals trying to identify their "family's" scent and locate their "territory." Learners mark their territories and sniff out other territories

Habitable Worlds
Source Institutions
In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

Seed Adaptations
Source Institutions
By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from pred

Super Soaking Materials
Source Institutions
In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.

Observing Cells
Source Institutions
In this playful activity, learners explore the structure of the cell—the basic unit of every living organism—by creating a model of cell structures using soap bubbles, and by examining a slice of onio

Paleontologists: Can You Dig It?
Source Institutions
In this activity, learners explore the work of paleontologists.

Source Institutions
In this activity, learners explore dinosaur fossils by making cast models of a T. rex. First, learners read about and research how dinosaur fossils form.

Iodine Investigators!
Source Institutions
In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

Waterhouse Hawkins and the Nano Dinosphere Museum
Source Institutions
In this activity, learners explore dinosaurs and fossils by creating a diorama.

The Adaptation Game
Source Institutions
To convey the concept of how animals adapt to survive, this game asks learners to imagine what adaptations a given animal would need to live in a certain environment—including environments where such

The Wave
Source Institutions
In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal

Cool It
Source Institutions
In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

Mystery Marauders
