Fill in the blank:
Sound is energy carried by waves of __________ particles.
vibrating
True or False?
Sound cannot travels through all solids, liquids and gases.
Name the form of energy:
A battery in a child's toy.
Chemical Energy
Name the form of energy:
Energy that comes from vibrations that travel through air or other materials.
Sound Energy
In order, name the forms of energy that are being transferred:
A lamp plugged into the wall (3)
Electrical => Light + Heat
What are the two types of sound?
Natural & Artificial
Which one does sound travel fastest through? Solid, liquid or gas? Explain why.
Solid. A solid has more particles tightly packed together for the sound waves to vibrate against.
Name the form of energy:
A roller coaster speeding down the first big hill.
Kinetic Energy
Name the form of energy:
Energy that travels in straight line as waves and can pass through empty space.
Light Energy
In order, name the forms of energy that are being transferred:
A blender crushing ice (3)
Electrical => Mechanical + Sound
Fill in the blank:
Volume can be ________ and ________.
Soft/quiet and loud.
Fill in the blank:
Pitch can be ________ and ________.
Low and High
Name the form of energy:
A plant producing oxygen through photosynthesis.
Chemical Energy
Name the form of energy:
Energy produced by the movement of electrons.
Electrical Energy
In order, name the forms of energy that are being transferred:
Clapping your hand together (2)
Mechanical => Sound
What unit measures volume?
Decibels (dB)
Why can't sound travel in space?
Sound cannot travel in space because there is not matter in space and the sound waves need matter to vibrate against. Space is an empty vacuum.
Name the form of energy:

Mechanical Energy
Name the form of energy:
Energy from the movement or position of an object (combines kinetic and potential).
Mechanical Energy
In order, name the forms of energy that are being transferred:
A hair dryer blowing your hair. (4)
Electrical => Mechanical (fan) => Heat + Sound
What unit measures pitch?
Hertz (Hz)
