Particles & Matter
I am anything that takes up space and has mass.
What is matter?
I have a fixed shape and a fixed volume. My particles are locked in place.
What is a solid?
It's what happens when sugar is stirred into water and seems to vanish.
What is dissolve? (dissolving)
I am a material made of only ONE type of particle. Pure water and table salt are examples of me.
What is a substance?
This is the method you would use to get salt back from saltwater.
What is evaporation (boiling)?
I am a tiny building block that makes up matter — too small to see with the naked eye.
What is a particle?
I have a fixed volume but no fixed shape. I take the shape of whatever container holds me.
What is a liquid?
Boil away the water from sugar water, and you will find this left behind.
What is sugar? (sugar crystals)
I am a combination of two or more substances whose particles are NOT joined together.
What is a mixture?
The fact that a mixture CAN be separated into its parts proves this about its particles.
What is they are not joined together?
A pencil sits perfectly still on a desk, yet I am happening inside it right now.
What is vibration? (particle movement?)
I have no fixed shape AND no fixed volume. My particles spread to fill any container.
What is a gas?
This process allows us to recover a dissolved solid from a solution.
What is evaporation?
A type of mixture where the particles are spread evenly throughout the mixture.
What is a solution?
When people make paper from wood, they separate this substance from the other materials in wood.
What is cellulose?
You cannot see me, but I take up space and have weight. I fill balloons and basketballs.
What is air?
When liquid is poured from a tall glass into a shallow bowl, I change — but my friend, ____ does not.
What are shape and volume?
When sugar dissolves in water, the sugar particles do this.
What is spread evenly throughout the water?
I look like a single shiny substance, but I am actually a solid solution of metals. I am often used to make utensils.
What is stainless steel?
This is the best method to use to separate fruit salad.
What is physical sorting?
To prove that air has mass, a student does this to a balloon before and after inflating it.
What is weigh it?
This is why a solid keeps its shape.
What is, because it's particles are locked in place?
To prove matter doesn't disappear when sugar dissolves, you can do this.
What is evaporate the water to recover the sugar?
If you break a single particle of water into smaller pieces, this happens to its properties.
What is they change? (they lose their properties?)
This is the best way to separate iron particles from sand.
What is a magnet?
