In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

Investigate how force and thrust work to propel rockets into outer space. Build a rocket: a blown-up balloon taped to a drinking straw threaded through some string.

In this activity, learners will explore their center of gravity.

This is an activity about circular motion. Learners will explore the laws of motion and force by observing circular motion.

In this activity, learners explore the history of making objects from glass and artistry of Dale Chihuly.

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

Listen to the beat of gravity. By taking two strings with weights tied to them at different, yet uniform intervals, you can hear the uniformity (and rhythm) of gravity's accelerating pull.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

Learners follow the template to build and fly a paper helicopter.

This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.

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 explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

During this activity, learners take part in a variety of tasks which involve moving and balancing different body parts.

Build your own Mini Mini Golf Course and learn about hands-on building and design, basic circuitry, motion modules and more!

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
