Physical Properties of Matter
What is temperature?
Temperature is a measure of how hot or cold something is.
What are the three states of matter?
Solid, liquid, and gas.
What is a mixture?
A mixture is a combination of two or more substances that can be separated easily.
What does "conservation of matter" mean?
It means that matter cannot be created or destroyed, only changed.
What should you wear for safety in the lab?
You should wear safety goggles and a lab coat.
What tool measures mass?
A scale
What is a solid?
A solid has a definite shape and volume.
What is a solution?
A special type of mixture where one substance dissolves in another and mix evenly throughout.
What happens to matter in a mixture?
The matter retains its properties and can often be separated again.
Why is it important to follow safety rules?
It is important to prevent accidents and injuries.
How does a magnet interact with metal?
A magnet attracts certain metals like iron.
What is a liquid?
A liquid has a definite volume but takes the shape of its container.
Can you name a liquid solution?
Salt and water
Sugar and water
Lemonade

Give an example of a mixture that conserves matter.
Mixing sand or soil with water conserves matter.

What is relative density?
The ability to sink or float.
What is a gas?
A gas has no definite shape or volume and fills its container.
What happens when you mix oil and water?
They do not mix and will separate; oil floats on top of water.
How do we know matter is conserved?
We observe that the total amount of matter before and after mixing remains the same.
Why should you never eat or drink in the lab?
Food and drinks can contaminate experiments and be unsafe.
What is magnetism?
Magnetism is a force that can attract or repel certain materials.
How do particles behave in a gas?
Particles in a gas move freely and are spread out.
How do you separate a mixture?
You can use heat to boil so the water will evaporate.
How can you tell if matter is conserved?
If the total mass before mixing equals the total mass after mixing, matter is conserved.
What equipment is essential for lab safety?
Essential equipment includes goggles, gloves, and a first aid kit.
