Matter Matters
Anything that has mass and takes up space is called what?
Matter
What do we call two or more substances combined together that can still be separated?
Mixture
Which tool could you use to separate iron pieces from another material?
Magnet
What property do we measure when using a triple-beam balance?
Mass
What happens when sugar or salt seems to disappear after being mixed into a liquid?
It dissolves.
When we measure the amount of matter in an object, what are we measuring?
Mass
Lemonade, tea, and Kool-Aid are examples of what type of mixture?
Solution
Iron is mixed with pepper. What tool would BEST separate the two substances?
Magnet
What tool is used to measure the mass of an object?
Triple-beam balance
When a substance dissolves, does it disappear completely?
No. It is still present in the solution.
What state of matter has a definite shape and takes up a definite amount of space?
Solid
Salad, trail mix, and gravel are examples of what?
Mixtures
A teacher mixes markers, erasers, and paper clips together. What is the BEST way to separate them?
Sort them by their physical properties/type.
What property are you measuring when you use a graduated cylinder?
Volume
A student mixes sugar into water until the sugar can no longer be seen. What has the student created?
A solution.
Which state of matter does NOT have a definite shape or volume?
Gas
What type of mixture has substances spread evenly throughout it?
Solution
Sand is mixed with water. Is this a mixture or a solution?
Mixture
Which tool would be BEST for measuring the volume of a liquid?
Graduated cylinder
Clay sinks to the bottom of a liquid while plastic floats at the top. What property helps explain why this happens?
Density.
A student has two objects that are the same size, but one has more mass. What property could explain why one object feels heavier?
Density
A student mixes salt into water and can no longer see the salt. Did the salt completely disappear? Explain.
No. The salt dissolved and is still present in the solution.
A student has a mixture of sand, iron pieces, and water. What could the student do to separate the iron from the rest of the mixture?
BONUS: How would I separate the rest?
Use a magnet to remove the iron.BONUS: Put the sand and water mixture through a filter.
A student needs to determine both the mass and liquid volume of a substance. What TWO tools should the student use?
A triple-beam balance and a graduated cylinder.
Question: A student adds a substance to water. After stirring, the substance spreads evenly throughout the water and can no longer be seen. Is this most likely a mixture or a solution? How do you know?
A solution because the substance dissolved and became evenly distributed throughout the water.
