Thermal Energy
What is thermal energy
Energy from the movement of particles in matter
What is kinetic energy?
Energy of motion
Name an example of something that uses electrical energy
TBD by teacher
Where is chemical energy stored?
In the bonds of atoms and molecules
True or False: Energy can be created or destroyed
False
When something feels hot, does it have more or less thermal energy than something cold?
More
What is potential energy?
Stored energy or energy due to position
What material allows electricity to flow easily — metal or rubber?
Metal
What are two examples of things that store chemical energy?
Food and batteries
What is Miss Y's favorite color?
Orange
How does heat move — from hot to cold, or cold to hot?
From hot to cold
A ball at the top of a hill has what type of energy?
Potential
What do we need for electricity to flow — an open circuit or a closed circuit?
Closed circuit
When you eat food, what happens to the chemical energy inside it?
Your body changes it to mechanical energy, then to thermal energy
What college did Miss Y go to?
Illinois State University
What happens to the particles in a substance when you heat it up?
They move faster
When the ball rolls down the hill, what happens to its energy?
Potential energy changes to kinetic energy
What is happening when you turn on a flashlight? What energy does it start with and changes to?
Chemical energy from the battery changes to electrical energy, then to light and heat.
What type of energy change happens in a battery that powers a toy car?
Chemical energy → electrical → mechanical
How many siblings does Miss Y have?
Two
If you rub your hands together to make them warm, what kind of energy is changing into thermal energy?
Mechanical energy → thermal energy.
A person on a swing keeps swinging back and forth — explain what energy changes are happening
It switches between potential and kinetic energy as it moves
Why do we need a complete circuit for electricity to work?
The energy can only flow when the path is closed
You eat breakfast, run to school, and feel warm and full of energy. How is chemical energy helping you do that?
The chemical energy from food changes to mechanical energy for movement and thermal energy to keep you warm.
