In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this activity, learners will train to increase bone strength and to improve heart and other muscle endurance by performing jump training with a rope, both while stationary and moving.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

Learners attach an egg to a rubber-band bungee cord and drop the egg.

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

Learners investigate how drag affects the falling rate of objects.

In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing
