YES OR NO
Would the following objects still work if there was no electricity?
car, bus, truck
YES
*they all runs on gas
Which has more stored energy?
a domino set up high or a domino set up low
a domino set up high
*the more height energy an object has, the more stored energy it has
Name how electrical energy is important in your life. (examples of how you use every day)
* use cell phone (electrical energy to charge)
* video games (electrical energy to play)
* turning lights on when it gets dark (electrical energy to plug in lamp)
* use microwave to heat up food (electrical energy to power microwave)
***any other example that uses electricity**
The term for something that allows energy to flow.
conductor
When making the flashlight (think back to the flashlight experiment), which side of the battery did the short end of the LED attach to?
short side attached to the negative side of the battery
Would the following object still work if there were no electricity?
faucet
YES
Which has more stored energy:
a roller coaster's high hill or a roller coaster's low hill
high hill
*the high hill has more potential/gravitational energy
TRUE OR FALSE
Plastic is a conductor.
FALSE
The term for a material that does not allow electricity to flow through it.
insulator
Give an example of how electrical energy is used to create SOUND energy.
*any of the following
TV, computer, phone
Would the following objects still work if there was no electricity?
lamp/light/nightlight
no
*all those objects need to be "plugged in" to work
Could you create a domino chain reaction model if you put dominos on their side (NOT standing up high)?
No, there would not be enough stored energy in the dominos to hit into the next domino in order to make it move
When creating a flashlight (think back to our flashlight experiment), what material was our conductor?
aluminum foil
Name the two conductors that we discussed.
aluminum and copper
Give an example of how electrical energy is used to create MOVEMENT energy.
*Any of the following*
elevators, escalators, fans, vacuums
Would the following objects still work if there was no electricity?
cell phone, microwave, TV, or ceiling fan
no
*all of those items need electricity to work
True or False
Energy flows from positive to negative.
FALSE
energy from from negative to positive
Why was aluminum foil a good material to use in our flashlight experiment?
it is a conductor and allowed energy to flow from the battery to the LED bulb
conductor
Give an example of how electrical energy is used to create LIGHT energy.
*any of the following*
night light, TV, digital alarm clock, lamps, computer
Would the following object still work if there was no electricity?
air conditioner
NO
*air conditioners need electricity to run (work)
When making the flashlight (think back to the flashlight experiment), which side of the battery did the long end of the LED attach to?
the long side of the LED attached to the positive side of the battery
How does electrical energy flow?
Energy flows from negative to positive
What would I need to add to make a complete circuit if I had the following items:
* light bulb
* wire
* metal screw
a BATTERY to give energy
the wire and metal screw are conductors so they would allow the energy to travel from the battery to the light bulb
Give an example of how electrical energy is used to create HEAT energy.
hair dryer, iron, curling iron, microwave, heater
