What tool measures length, and what are the units of measurement?
Ruler
cm, mm, meter, km

How do you measure the amount of matter in an object?
With a balance. Mass is a measure of the amount of matter in an object.
100
True or False: All solutions are mixtures.
True
100
What is buoyancy?
The ability to float in water
100
What are the three states of matter?
Solid, liquid, gas
200
What tool measures temperature, and what are the units of measurement?
Thermometer
Degrees Celsius
200
How do you measure the amount of space that matter takes up?
Volume is the measure of how much space matter takes up. You can measure volume with a graduated cylinder.
200
True or False: All mixtures are solutions.
False
200
What is density?
Density is relationship between matter and volume. Volume > Mass = less dense
Mass > Volume = more dense

An ice cube melts. What is the change in the state of matter?
Solid to liquid
300
What tool measures volume, and what are the units of measurement?
Graduated cylinder OR displacement can
Milliliters (mL)
300
What is the volume of the liquid?
24 milliliters
300
What makes a solution a special kind of mixture?
One compound dissolves into another compound. It looks like one compound has disappeared, but it is just evenly distributed in the other compound.

Why does a golf ball sink?
It is solid; it has a density greater than water so it sinks.
300
What property causes a change in state of matter?
Temperature
400
What tool measures mass, and what are the units of measurement?
Triple-beam balance
Grams

What do you know about the mass of the fruit in this picture?
The fruit has a mass less than 1kg
400
Which is a solution:
Milk and cereal OR
Salt and water
Salt and Water
400
How does air in an object (like a plastic ball) help it to float?
The air makes the density of the ball lighter than the density of water, so it floats.
400
What do these three containers show? What is happening to the temperature?
Gas to liquid to solid. The temperature is decreasing (getting colder)
500
Are mass, temperature, volume, and length considered properties of matter?
Yes!
500
What is the temperature in degrees Celsius?
About 30 degrees Celsius
500
What are two things that are true about mixtures?
They are two or more different things combined together. The properties of the compounds do not change. You can separate them back into their original compounds.
500
A solid block of wood will float on water. Why?
The density of the wood block is less than water. The weight of the water displaced by the block is greater than the weight of the block, so the block floats.
500
What state of matter is this? How do you know?
It is a solid. The particles are packed together and it does not take the shape of its container.
