This state of matter has a definite shape and volume.
What is a solid?
A change where matter changes shape or size but no new matter forms.
What is a physical change?
Tiny pieces of matter too small to be seen.
What are particles?
Water changing from liquid to solid is called this.
What is freezing?
Information that supports a scientific claim.
What is evidence?
This state of matter takes the shape of its container but keeps the same volume.
What is a liquid?
Crushing a can is an example of this kind of change.
What is a physical change?
Scientists use these to explain things too big or small to see directly.
What are models?
Water changing from gas to liquid is called this.
What is condensation?
Condensation on a cold window is evidence that this is in the air.
What is water vapor?

What is none?
Sugar seems to disappear in water because it does this.
What is dissolve?
This process changes liquid water into water vapor.
What is evaporation?
Heating water helps sugar dissolve faster because particles move this way.
What is faster?

What is density?
This scientific idea says matter is conserved during physical changes.
What is conservation of matter?
When dissolved salt water evaporates, this is left behind.
