Electric Paddle Boat
Source Institutions
In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.
Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.
Make a Comeback Can
Source Institutions
Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.
Two Ball Bounce
Source Institutions
This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.
Micro Automata
Source Institutions
In this activity, learners build small animated toys that move.
Tinkering with Tops
Source Institutions
In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.
Hand Spin Helicopter
Source Institutions
In this activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.
Stretch Your Potential
Source Institutions
In this activity, learners create a toy that demonstrates the First Law of Thermodynamics or the Law of Conservation of Energy.
Paddle Boat
Source Institutions
In this activity, learners build an old-fashioned paddle boat out of simple materials.
Dough Creatures
Source Institutions
In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.
Raceways
Source Institutions
In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.
Rubber Band Racers
Source Institutions
In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.
What is Energy?
Source Institutions
In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.
Can Energy be Created or Destroyed?
Source Institutions
In this activity, learners explore conservation of energy by experimenting with a solar cell light device.
Luminescence
Source Institutions
In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.
Rollin’ Rollin' Rollin'
Source Institutions
In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.
Rolling Returns
Source Institutions
In this activity, learners build a special rolling can that returns back to you when you push it forward. Use this activity to demonstrate the transfer of energy between kinetic and potential energy.
Extra Bounce
Source Institutions
In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.
Rubber Band Boat
Source Institutions
In this activity, learners build styrofoam boats powered by twisted rubber bands.
Interactive Gumball Machine
Source Institutions
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.
