Sink or Float?
100
Anything with mass and volume
What is matter?
100
A metal spoon is an example of this.
What is a conductor?
100
Peas and carrots
What is an example of a mixture?
100
Heat moving from a stove to a pot?
What is conduction?
100
This determines if an object will float or sink in water.
What is density?
200
You can tell this by how its particles move.
What is a solid, liquid, or gas?
200
Wood and plastic are examples of this.
What is an insulator?
200
After it rains, water on the street evaporates.
What is a phase change?
200
They limit the amount of heat that passes through them.
What is the purpose of materials that are insulators?
200
The object sinks.
What happens when something has more density?
300
You use this to compare and measure the mass of two objects?
What is a balance?
300
It is the measure of the average amount of motion in particles of matter.
What is temperature?
300
A nail rusts
What is an example of a chemical change?
300
The method of heat transfer that does not require matter.
What is radiation?
300
The object floats.
What happens when something has less density?
400
the particles are tight together
What is a solid?
400
You feel this when you feel the warmth from a light bulb on your skin.
What is radiation?
400
butter melting
What is a phase change?
400
the ability to cause change or do work
What is energy?
400
The reason a cork floats in water.
What is less density?
500
Its particles roll over one another.
What is a liquid?
500
It forms when heated air expands and cooler air sinks below the warmer air.
What is convection current?
500
campfire started
What is a chemical change?
500
It readily allows heat to move through it.
What is a conductor?
500
The reason steel sinks in water.
What is more density?
