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.

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

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this activity, learners are invited to imagine the park of their dreams!

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 compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

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

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

In this activity, learners explore the concepts of natural selection and observable traits in a game that can be played at home.

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

In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

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?
