Properties of Matter
This property describes the amount of space an object takes up.
What is Volume?
This state of matter has a definite (fixed) shape and a definite volume.
What is a Solid?
An ice cube melting or a piece of paper being shredded are examples of this type of change.
What is a Physical Change?
This is the best tool to use if you need to separate iron filings from a pile of sand.
What is a Magnet?
If you want sugar to dissolve in your tea faster, you should do this with your spoon.
What is Stirring?
If you have a red, rough brick and a smooth, blue marble, you are comparing them using these two types of observable properties.
What are Color and Texture?
This state of matter takes the shape of its container but still has a fixed volume.
What is a Liquid?
This type of change results in a brand-new substance being formed, like rust on a bike or ash from a fire.
What is a Chemical Change?
To separate a mixture of large rocks and fine dirt, you would use this tool which works based on particle size.
What is a Sieve (or Screen/Strainer)?
A tablet of Alka-Seltzer will fizz faster in a cup of this temperature water.
What is Hot Water?
This is the tool a scientist would use to measure the mass of a solid object.
What is a balance/scale?
This state of matter will expand to fill whatever container it is put in, no matter how large.
What is a Gas?
Seeing bubbles, smelling a new odor, or seeing a change in color are all clues that this type of change has happened.
What is a Chemical Change?
If you dissolve salt into water, you have created a solution. What is the only way to get the salt back out?
What is Evaporation (or boiling the water)?
One of these will dissolve faster: a whole sugar cube or a spoonful of crushed-up granulated sugar.
What is the Crushed/Granulated sugar?
True or False: If you take a solid piece of clay and squish it into a new shape, its mass stays the same.
What is True?
In this state of matter, particles are packed very tightly together and only vibrate in place.
What is a Solid?
When you add heat to liquid water and it turns into water vapor (a gas), is that a physical or chemical change?
What is a Physical Change? (It is still water, just a different state).
This term describes a material, like salt or sugar, that is able to dissolve in water.
What is Soluble?
Name two conditions that would slow down the process of salt dissolving in water.
Using cold water and not stirring.
A beach ball is much larger than a baseball, but the baseball is heavier. Which object has more volume, and which has more mass?
The beach ball has more volume; the baseball has more mass.
When you breathe air into a balloon, you are observing that gases have mass and take up space. How does the volume of the air change when it goes from the room into the balloon?
The volume decreases (it is compressed/squeezed to fit the balloon).
Explain how temperature affects a chemical change, like a glow stick or a piece of fruit rotting.
Higher temperatures usually make chemical changes happen faster.
Why is sand considered "insoluble" in water?
Because it does not break down/dissolve and can be separated by a filter.
In an experiment, you keep the amount of water and the amount of sugar the same, but you change the temperature of the water. What is the variable?
What is Temperature?
