In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

In this activity, learners create their own archaeological profiles.

In this activity (page 2 of PDF under GPS: Alligator Habitat Activity), learners will study the adaptations different fish species have developed to survive in their habitats.

In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

In this activity, learners investigate passive solar building design with a focus solely on heating.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.

In this earth science activity, learners conduct a series of short experiments to explore how rocks change.

In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.

Educator Amy O'Donnell from the American Museum of Natural History guides learners to create a diorama of a coral reef.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

This activity (located on page 4 of the PDF under GPS: Baby Dinosaurs Activity) is a full inquiry investigation to determine the age of fossils based on where they are discovered.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
