Deep Sea Diver
Source Institutions
In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.
Get-Moving Game
Source Institutions
In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.
Measure the Pressure: The "Wet" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.
Bend It, Break It
Source Institutions
In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.
Colors, Colors?
Source Institutions
In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th
Why do Hurricanes go Counterclockwise in the Northern Hemisphere?
Source Institutions
In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.
Shake it up with Seismographs!
Source Institutions
In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.
Build a Battery
Source Institutions
Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.
Desert Water Keepers
Source Institutions
In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.
Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
Magnetic Marble Run
Source Institutions
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.
Ripening of Fruits and Vegetables
Source Institutions
In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.
Folding Matters
Source Institutions
In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.
Flower Powder
Source Institutions
In this outdoor activity, learners use artificial bees and paper models of flowers to find out how bees transfer pollen from one flower to another.
Recycle Your Own Paper!
Source Institutions
In this activity (page 2 of PDF under GPS: Garbology Activity), learners will prepare sheets of homemade recycled paper from several different source pulps.
DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.
Assembly Line
Source Institutions
In this activity, learners work individually to assemble a product and then work in teams to design, construct, test, and redesign an assembly line process whose product must meet specific quality con
Where Does Life Live?
Source Institutions
In this activity (on pages 22-24 of the PDF), learners match extreme enviroments with life forms they support.
Build a Big Wheel
Source Institutions
In this activity, learners explore how engineers have developed big wheels or Ferris wheels.
