A material that electricity cannot easily flow through.
What is an INSULATOR?
A circuit that has a break along the path so that energy cannot flow.
What is an OPEN CIRCUIT?
When energy moves between two objects or places.
What is ENERGY TRANSFER?
Petroleum, natural gas, coal
To make something go faster you
Add more energy to it
A material that electricity can easily flow through.f
What is a CONDUCTOR?
A circuit that is complete and allows energy to flow.
What is a CLOSED CIRCUIT?
When energy changes from one form to another. For example, when electrical energy transforms into kinetic energy.
What is ENERGY TRANSFORMATION?
Fire and explosions
What happens if you overload a circuit?
Which rubber band was better in the twistomatic
Thick for faster spins, Thin for longer ride
Name a conductor.
What is....
*metal
*water etc.
A device that allows the circuit to be opened or closed.
What is A SWITCH?
The heater is running in my house. When I open the window, the hot air moves out of it. What is this an example of?
(Transfer or Transformation?)
What is TRANSFER?
Name a reason it is important to conserve energy?
* many sources of energy are non-renewable
*some forms of energy cause pollution
*pollution from energy use can cause the earth to get warmer which leads to many problems
Where does the rider on a rollercoaster have the most energy?
At the top of the highest hill
Name an insulator.
What is...
*rubber
*plastic
*fabric etc.
Is this circuit open or closed currently?
What is OPEN?
When I plug in a fan and the fan starts blowing. What is this an example of?
(Transfer or Transformation?)
What is TRANFORMATION?
(Electricity is transferred to mechanical or kinetic energy.)
Name 2 things a 4th grader could do to conserve energy?
*turn lights out when not in a room
* play video games less
*turn devices OFF when not in use
*don't open the fridge without a good reason, close it quickly
* keep windows closed when the air conditioner or heater is on
*take showers (use less water and heat)
*recycle and reuse things as much as possible
The Marble goes into the alligator's mouth
What happened when one marble's kinetic energy was transferred to another one?
Explain why a tile floor and a carpeted floor feel like they are different temperatures even if they are in the same house.
The reason they feel different is that the tile is a conductor and it will draw the heat away from your body but the carpet is an insulator so you will not feel the heat transfer as strongly.
Explain how an electric outlet and plug make a circuit.
The cord has two wires in it and when you put the plug into the outlet, you make a closed circuit (with wires to and from the energy source) causing the "load" (whatever you are powering) to light up.
A plant uses the light energy of the sun into food so it can grow.
(Transfer or transformation?)
What is TRANSFORMATION?
Name 3 forms of energy.
What is...
*light
*heat
*sound
*kinetic
*potential
