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.

In this activity, learners discover how bats use echolocation to get information about objects in their environment. During the activity, one learner whispers into a tube.

In this activity, learners listen to a story and tell a story of their own as they learn about the importance of elders in Native American cultures.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this online activity, learners test their ability to hear different frequencies and compare their frequency range with the frequency range of other animals and insects.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

This activity is a fun way to show two stages in a Monarch butterfly's life cycle. Learners will create an optical illusion that can be flipped from caterpillar to butterfly.

In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this activity, learners touch and observe skulls of sharks and rays to learn about their diversity (over 400 species of sharks alone!).

This PDF contains 12 calendars (12 months). Each month contains activities about math. Things to do on familiar holidays (like July 4), less common holidays (like Backward Day), and any day.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

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

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.

In this interactive game, learners will test their memory of animal and insect sounds. Flip over cards, listen to the sound, and try to find the ones that match.
