In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

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, learners explore dinosaur fossils by making an edible treat. First, learners read "Dinosaur Bones" by Aliki to examine how fossils are formed.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

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 model hot spot island formation, orientation and progression with condiments.

In this genetics activity, learners create imaginary creatures known as "Reebops" to explore the relationships between genes and inherited traits.

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.
