Wood, Food, Coal
48
What is a system
It is something that has 2 or more parts that work together to make something happen
49
Example of input energy
The paraffin you put in a lamp
50
Example of output energy
The light that shines from the lamp
51
What are electrical appliances
It's appliances that use electricity to work

A thin piece of skin inside your ear that vibrates when sound waves hit it
58
What is a nerve
A group of fibres that carries messages between your brain and a part of your body
59
How does sound energy move
It always moves away in all directions from the part that is vibrating
60
What happens to the air around an object when the object vibrates?
The air also vibrates
61
How do we hear
Sound waves travel through the air The ear catches the sound wave The sound wave travels along the ear canal The sound wave hits the ear drum and makes it vibrate Vibrations travel through the bones of the middle ear Vibrations travel though the inner ear A nerve takes the message to the brain which makes you hear the soundean
62
Can you sometimes hear and feel vibrations
Yes

What is sound a form of?
A form of energy
67
Why do you think some sounds are louder than others
If you put a lot of energy in the output energy will be more. Like if you blow on a whistle hard the sound that comes out of it will be louder.
68
What happens when we turn up the volume of the TV
The speakers get more energy, that makes bigger vibrations and louder sound
69
