States of Matter
What are the three states of matter we learned?
Solid, liquid, gas.
This property tells us whether something is red, blue, green, etc.
Color.
What is matter?
Anything that has mass and takes up space.
I am soft, fluffy, white, and flexible. What could I be?
Cotton/cotton ball.
You touch an object and it feels scratchy. What property did you observe?
Texture
Which state of matter keeps its own shape?
Solid.
This property describes how something feels, such as smooth, rough, or fuzzy.
Texture.
Is a desk matter?
Yes
I am hard, smooth, and made of metal. A magnet may attract me. What could I be?
A paper clip
You want to know whether an object bends easily. What property are you testing?
Flexibility
Which state of matter takes the shape of its container but can be poured?
Liquid.
This property tells whether a material is hard or soft.
Hardness.
Is AIR matter?
Yes
I am clear, hard, smooth, and stiff. What material could I be?
Glass
Can you know for sure that something is magnetic just by looking at it? What do you need to do?
No. You need to test it with a magnet.
Which state of matter spreads out to fill its container?
Gas.
This property tells whether something bends easily or stays stiff.
Flexibility.
What is a property of matter?
Something we can observe or measure about matter.
I am soft, lightweight, flexible, and fuzzy. What could I be?
Feather
Why is using more than one property helpful when identifying a material?
Different materials can share the same property, so more properties provide better evidence.
What does state of matter mean?
The form matter is in, such as solid, liquid, or gas.
This property tells whether an object is attracted to a magnet.
Magnetism.
Why do scientists study properties of matter?
To describe, compare, and identify materials.
Two objects are both silver and smooth. What should a scientist do to help tell them apart?
Test or compare another property.
A mystery object is hard, smooth, stiff, and magnetic. Name THREE pieces of evidence you could use to describe it.
Any three: hard, smooth, stiff, magnetic.
