How we made watering plants fun

Materials Used:

4Ft x 4Ft Wood plank

Batteries operated fan

String

Plastic bottle caps

Wooden dowels

Card board

Hot Wheels track

Zip tie

Marbles

Plastic water bottles

Tape

Styrofoam

Plastic cup

Tin foil

Balloon

Popsicle sticks

Toilet paper roll

Needles

Mesh

Wood

Hot glue

This is how our Energy Transfer Machine works, Chemical to electrical (Battery)-essentially its a release of energy when chemical reactions take place inside a cell. Electrical to kinetic (Rotational KE in fan motor).Electrical to heat and sound (the fan motor makes some sound and gets heated, (these are undesirable conversions that dissipate energy).

Gravitational Potential Energy to Kinetic Energy, all of the slides and falls, car, marble etc. When the car collided with the marbles we noticed a few things(a) Sound (b) Vibration (c) There will also be some heat, these dissipative conversions take place when PE is converted to KE. The car will go down the ramp, and knock the “Jenga” blocks down, which will make the golf ball go down the tunnel, this is Gravitational Potential Energy to Kinetic Energy. When the golf ball hits the balloon filled with water, the balloon will roll into the cup with pins and pop, and water our plant, this is Gravitational Potential Energy in action.

    You four made a great team, and that showed in your excitement and the quality of the machine. Good job describing all of the steps, including the loss of energy.
