Matter, Mass, and Volume
This is anything that has mass and takes up space.
Matter
This state of matter has a definite shape and a definite volume.
Solid
This is water in its solid state.
Ice
All matter is made of tiny pieces called these.
particles
A student blows air into a plastic bag and seals it. The bag becomes larger. This shows that air takes up this.
space
This tells how much matter is in an object.
Mass
This state of matter has a definite volume but takes the shape of its container.
Liquid
Water that you drink from a cup is in this state of matter.
liquid
When matter becomes warmer, its particles usually move this way.
faster
You cannot usually see individual air particles, but you know they are present because you can observe their effects. Scientists often use this to represent things that are too small to see.
model
This tells how much space an object takes up.
Volume
This state of matter does not have a definite shape or definite volume.
Gas
Water vapor is water in this state of matter.
gas
When matter becomes colder, its particles usually move this way.
slower
A student places an inflated balloon in a cold container. The balloon gets smaller. The temperature change is the cause. The balloon getting smaller is the ________.
effect
A basketball filled with air takes up more of this than a flat basketball.
Space or Volume
Milk poured from a carton into a cup changes this property but keeps its volume.
Shape
When ice melts, it changes from this state to this state.
solid to liquid
A balloon becomes smaller in a very cold place because the air particles inside begin moving this way.
more slowly
A balloon is moved from a cold container into a warm room. Predict what happens to the balloon and explain why.
the balloon gets larger because the air particles move faster as they warm up
A student weighs an empty balloon and then weighs the same balloon after it is filled with air. The filled balloon weighs more. This is evidence that air has this property.
Mass
A metal bottle, the water inside it, and the air above the water represent these three states of matter in order.
Solid, liquid, and gas
Ice, liquid water, and water vapor are different forms of the same substance. Together they show that water can exist in this many states of matter.
Three states of matter.
A cold balloon is placed into warm water. The particles begin moving faster, so the balloon will most likely do this.
get larger or expand
A student says, “Air is not matter because I cannot see it.” Use two pieces of evidence to prove the student wrong.
air has mass and air takes up space
