What has the ability to make a change?
Energy
Give two examples of how we can see light energy.
Is this true: energy can 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 is a conductor.
Conductors allows electricity to easily travel through them. Some good conductors include metals.
Energy transfers when objects collide. True or False?
True, think of a baseball hitting a bat, energy moves to the ball.
Why do the lights turn off in class when we hit the switch?
The closed circuit is turned into an open circuit, so energy cannot flow through.
Name three types of renewable energy sources.
Water, wind, and solar energy
When the weight of an object increases, the amount of energy: increases or decreases?
Increases, think of two kids jumping into a pool, the one with more weight will have more energy
How can we generate electricity without using fossil fuels?
We can use solar power, hydroelectric power, or wind power.
When Henry eats an apple, he will have energy to play in his soccer game later on. In order to run (mechanical energy) what type of energy does Henry use?
Chemical energy
When the speed of an object increases, the amount of energy: increases or decreases?
Increases, more speed means more energy is being used.
Microwave heating food is an example of this type of energy.
An example of radiation/ heat energy
This is what happens with potential energy and kinetic energy when a ball is thrown in the air.
The ball has the most kinetic energy when it is thrown, and potential energy at its highest.
Resources that cannot be renewed
Non-Renewable resources, for example fossil fuels like coal, oil, natural gas.
Energy from moving water can be converted into electrical energy. True or False?
True, think back to Boulderville, they could use water energy to power the town's electricity.
The difference between a parallel circuit and a series circuit
A parallel circuit will still allow energy to flow even if one part of the circuit is not working (example: New Christmas tree lights will work even if one light bulb won't)
Series circuit example: old Christmas tree lights, where if one light goes out, energy will not flow to the next part.
