What word means the ability to make a change?
Energy
Give two examples of how we can see light energy.
A person who uses their knowledge of science to design something in order to solve a problem
Engineer
What part is needed to allows electricity to pass through from place to place?
Wires
Is this true: can energy transform, or change, from one form into another.
Yes, energy can change from one form to another. For example, light energy can be captured by solar panels and transformed into electric energy to power a home, car, and many other things.
What does transfer mean?
to move something from one place to another
What other form of energy can we get when light energy is created?
thermal (maybe sound)
What is a system?
a group of parts that work together
Why do the lights turn off in class when we hit the switch?
EE stops flowing to the lights
To change form from 1 form to another
to convert
What forms of energy does a TV produce?
Light, Sound, maybe thermal

Chemical energy
The water in a swimming pool tends to be warmer in the daytime and cooler at night. What natural source of energy causes the difference?
The sun. (Solar energy provides thermal energy)
A machine that converts electrical energy
to another form of energy
An Electrical Device
the input for a microwave, used to heat food is this type of energy.
Electrical
