Forms of Energy
This type of energy travels as vibrations through the air so you can hear it.
Sound
A battery-powered flashlight transforms chemical energy into electrical energy, and then into this type of energy so you can see in the dark.
light
This is the unseen force that holds a rubbed balloon to a wall.
Static Electricity
For a lightbulb to light up, the wires must form a complete, unbroken loop, also known as this kind of circuit.
Closed Circuit
Materials that allow electricity to flow easily through them are called this.
Conductors
This is the type of energy that our bodies get from eating food.
Chemical
The scientific term for when energy changes from one form into another form.
Energy Transformation
If you rub two balloons on a carpet, they will both gain the same electrical charge. Because they have the same charge, they will do this when brought close together.
Push Apart (Repel)
This device is added to a circuit so you can easily open (turn off) and close (turn on) the circuit without unhooking the wires
Switch
Materials that are specifically chosen to prevent electricity from passing through them are called this.
insulators
This type of energy travels through wires in a circuit to power our devices
Electrical
A toy fire truck that drives around converts electrical energy into this type of energy.
Mechanical
When an object has a positive charge and another object has a negative charge, the opposite charges will cause them to do this.
Stick Together (Attract)
In a circuit with a battery, a switch, and a lightbulb, if the switch is pulled up and the bulb is off, the circuit is in this state.
Open Circuit
The inside core of an electrical wire is usually made of this specific metal because it is a highly efficient conductor.
Copper
A toaster provides this type of energy to change a soft slice of bread into crispy toast.
Thermal or Heat
Batteries store this type of energy, waiting to be transformed into electricity when connected to a circuit.
Chemical
Mateo charged a comb and saw small plastic foam pieces jump up to stick to it. This proved an electrically charged object can attract an uncharged object without doing this.
Touching
This is the component in a simple circuit that provides the source of energy to push the electricity through the wires.
Battery
The outside of an electrical wire is usually coated in this flexible material to act as an insulator and prevent electric shocks.
rubber or plastic
An everyday object like a television is useful because it transforms electrical energy into sound energy and this other type of energy.
Light
A solar-powered calculator transforms this type of energy from the sun into electrical energy.
Light or solar
If you rub a balloon on a carpet, the friction transfers electrons, giving the balloon this specific type of electrical charge. Positive or Negative
Negative
To complete a circuit, wires must be connected to the positive terminal and this other terminal on the battery.
If a student places a piece of metal and a piece of plastic in a circuit, electricity will only flow through the metal for this reason.
What is because metal is a better conductor than plastic?
