a form of matter that is constantly changing shape and volume. In this state, particles move freely and at high speeds.
What is A GAS?
A material that electricity cannot easily flow through.
What is an INSULATOR?
A circuit that has a break along the pat so that energy cannot flow.
What is an OPEN CIRCUIT?
When energy moves between two objects or places.
What is ENERGY TRANSFER?
A charged force that will either attract or repel an object.
What is MAGNETISM?
Anything that occupies space and has mass
What is MATTER?
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?
A metal that is made into a magnet by the electric currents moving through it.
What is an ELECTROMAGNET?
A form of matter that has definite volume, but changes shape based on it's container because the particles have room to move around.
What is A LIQUID?
Name a conductor.
What is....
*metal
*water etc.
A device allowing 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
The amount of matter (number of atoms).
What is MASS?
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 amount of space being taken up.
What is VOLUME?
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
