This activity (on page 3 of the PDF under GPS: Biodiversity Activity) is a full inquiry investigation into biodiversity.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most. Then, learners estimate the size of a Triceratops and T.

In this activity (located on pages 9-14 of PDF), learners visit a cemetery to examine the distinguishing characteristics of rock weathering.

In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.

In this activity, learners plant seeds and watch them sprout and grow inside a CD case.

In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s

In this classic activity, learners investigate natural selection by becoming birds foraging for food on an island.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

This activity is a sensory experience that recreates the sounds of a pond at night.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this nutrition/food science activity, learners conduct an experiment and record data to compare the amount of fat in different foods.

This is an activity about dinosaurs, fossils, and the work of paleontologists. Learners use hand tools (paint brushes, scoops, and sifters) to unearth fossil specimens in tubs of birdseed.

In this activity, learners collect worms and then observe how they move.

In this forensics activity, learners solve a mystery using “DNA” taken from the scene of the crime.

This is an outdoor activity designed to demonstrate evolution of feeding behavior in flocking, schooling or herding animals that maximizes allocation of food resources and enhances survival.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

In this outdoor activity, learners make models of homes that might protect small animals from the elements, then search living plants for real structures made by small animals.

In this fun activity for any size group, early elementary learners complete physical challenges while playing a game. Learners add new challenges to the "wheel of fitness" that they want to try.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.
