True or False: All matter has mass and takes up space (has volume)
True
What is the difference between qualitative and quantitative traits?
Qualitative - can observe
Quantitative - can measure
What does volume mean?
How much space something takes up

Which of the following units is the biggest: g, kg, or mg?
kg
What are melting/boiling points?
The point at which a substance boils or melts
What units could you use to measure volume of a liquid and a solid (name which for which)
Liquid - mL or L
Solid - cm3 or m3
75000 mL = ???? L

A student finds a rock with a mass of 200 grams and a volume of 50 cubic centimeters. What is the density of the rock?
40 g/cm3
Name a unit you can use to measure mass

What is the difference between weight and mass?
Weight takes into account the pull of gravity (you will always be heavier on Earth)
Gas, then liquid, then solid
