In this indoor and outdoor activity, learners discover that insects grow and develop as do all living things, going through a process known as complete metamorphosis.

In this activity related to dinosaurs, learners explore why animals live in families. Learners discuss and identify animals living in families or groups from images and photos.

In this activity, young learners (2 years and up) explore the world of insects and other "bugs" by Making a "bug hotel" with recycled objects.

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 activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.

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

In this activity, early learners simulate fossil prints in play dough or clay.

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.

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this activity, learners examine nanoscale structures of common things.

In this activity, learners will observe and record living things with in outlined outside space.

In this outdoor activity, learners will gather natural materials outside that they think a dinosaur would want to lay its eggs in.

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 explore dinosaurs and fossils by creating a diorama.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?
