This outdoor activity/field trip requires a place where minnows swim, such as a local pond or brook.

Investigate a flower's power of marketing by making an imitation flower that successfully signals a bee (or other pollinator of your choice) to visit.

In this activity, learners use models of fossilized dinosaur teeth to understand how dinosaur teeth were used.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.

This activity (located on page 3 of the PDF under GPS: Cave Swallows Activity) is a full inquiry investigation into bird behaviors.

In this activity, learners will simulate the interactions between a predator population of gray wolves and a prey population of deer in a forest.

Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

Plants need nutrients to grow. This is why we apply fertilizers to grass and food crops. In this activity, learners will explore how fertilizers can affect lakes and other bodies of water.

In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

In this activity, learners explore how to protect their skin while applying pesticides to plants.

In this game, learners create flash cards with an image on one side (of an animal, for example) and the sound that animal makes on the other.

This activity (on pages 35-43) lets learners analyze a "herd of elk" to detect the spread of a bacterial disease called brucellosis.

This activity was designed for blind learners, but all types of learners can use it to organize an interactive model for learning the classification system (taxonomy) of living things.

In this activity, learners collect, analyze, and interpret information about objects in order to classify them into a cladogram. Use this activity to talk about how scientists classify things.

In this outdoor activity, learners dig for and collect isopods (sometimes known as "roly-poly bugs" or "potato bugs" and other names).

This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.
