In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

Ancient trash tells archaeologists a lot about the past. In this activity, learners take a close look inside their trash can and think about the clues it offers about their lives.

In this outdoor winter activity, learners search for and create hibernation sites that will protect gelatin "animals" from freezing.

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

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

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this activity, learners investigate different types of bird beaks using household items which mimic different beak examples.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

Students design and build their own parachutes in this hands-on engineering project.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

In this fun hands-on activity, learners create a safety device to protect an egg "passenger" in a toy car crash. Learners experiment with different solutions to this very problem.

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 (page 5 of the PDF), learners will create a food web and explore food sources for different organisms. They will identify relationships between organisms in an ecosystem.

In this outdoor simulation game, learners search for pretend animals called "sticklers" to determine and map where they live (habitat) and how spread out they are in that area (distribution).

In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.

In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

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