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 activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.

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

Did you know that a Slinky makes a handy model of earthquake waves?

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 interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

In this physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.

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.

Make a copy of the first stethoscope with only a cardboard tube! René Laennec invented the first stethoscope in 1819 using an actual paper tube!

In this activity, learners discover how hard their hearts work to pump blood.

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.

In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

Build a glider that uses the same physics as a curve ball, for less than a dime.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.

In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.
