This activity (on page 3 of the PDF under GPS: Baseball Activity) is a full inquiry investigation into how "bounciness" relates to the distance a ball will fly when hit off a batting tee.

In this activity, learners investigate the properties of different types of balls.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this activity (on page 1 of the PDF under SciGirls Activity: Soccer Ball Kick), learners will investigate the transfer of energy using sports equipment.

In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.

In this activity, learners will explore how and why weight distribution works.

This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.

In this design challenge activity, learners invent a convenient way for someone using crutches or a wheelchair to carry small personal items.

In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.

In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.
