The Shape of Floatation
Source Institutions
In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.
Batter Up!
Source Institutions
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.
Measure the Speed of a Water Leak
Source Institutions
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.
Super Spinner
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.
Homemade Hovercraft!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.
Mega Bounce
Source Institutions
In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.
Cup Sailing Game
Source Institutions
In this online Flash game, learners will captain a sailing challenge, adjusting boat direction and sails, seeking the way to take greatest advantage of varying wind speeds and directions to catch the
Super Bounce
Source Institutions
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.
Bouncing Balloons
Source Institutions
In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.
Twirling in the Breeze
Source Institutions
In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.
Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.
Reusable Rockets
Source Institutions
This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.
Pedal Power
Source Institutions
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.
Gravity Fountains
Source Institutions
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.
Balloon Hovercraft
Source Institutions
In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.
Capturing Homemade Microgravity
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Microgravity) is a full inquiry investigation into how ordinary things behave in microgravity, similar to what astronauts experience.
Kites
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.
Testing Falling Peanut Butter Sandwich Myth
Source Institutions
In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi
Twirling Rope Frequency
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record
Marble Run!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.
