100
The three commons states of matter.
What are solids, liquids, and gases?
100
All matter is made out of these incredibly tiny particles.
What are atoms?
100
This property measures HOW MUCH matter is in an object.
What is mass?
100
The property measures how much SPACE an object takes up.
What is volume?
100
This property of matter measures how "tightly packed" an objects matter is.
What is Density?
200
For anything to be matter, it must do these two things.
What are have mass and take up space?
200
My particles hold together and hardly move. I have a definite shape and volume. I am the ___________ state of matter.
What is solid?
200
We measure mass using this metric unit.
What are grams?
200
We measure volume using these metric units (name at least one).
What are milliliters (mL) and cubic centimeters (cm^3)?
200

Is oil more or less dense than water??

What is less dense.

300
The temperature where a solid turns into a liquid because of heat.
What is the melting point?
300
My particles spread apart very easily and quickly. I don't have a definite shape, and my volume can change as well. I am the _________ state of matter.
What is gas (gaseous)?
300
You use this tool to measure an object's mass.
What is a balance? (Also accepting 'scale,' but technically that measures weight - science is weirdly specific, but it'll make sense if you spend enough time with it)
300
You use this tool to measure the volume of a liquid.
What is a graduated cylinder? (A beaker also works!)
300
Liquid A has a density of 2 g/mL. Liquid B has a density of 4 g/mL. Which one will sink to the bottom?
What is Liquid B? (More dense matter sinks below less dense matter; lighter matter rises above denser matter)
400
The temperature where a liquid turns into a gas because of heat.
What is the boiling point?
400
My atoms stay together, but can also move around. I don't have my own shape, but I have volume. I can be poured. I am the ___________ state of matter.
What is liquid?
400
True or False: Mass and Weight are the same thing.
FALSE!! Mass is a measure of matter, but weight is a measure of gravity pulling on an object. Consider this - if I send you to the moon, your mass does not magically change. Mass stays the same, but the moon's weaker gravity makes you weigh less.
400
True or False: When you pour a can of coke into a glass, the volume changes.
False - The coke still takes up the same space, so its volume is still the same. The SHAPE of the liquid changed.
400
A candy bar has a density of .95 g/mL. Water has a density of 1.0 g/mL. Will the candy bar sink or float?
What is float? The candy bar has a lighter desnity than the water, so it rises above the more dense water.
500
This state of matter can be found on the sun, in lightning, and in flourescent light tubes.
What is Plasma?
500
If I add heat to particles, how will those particles begin to change?
The particles will move quicker and will begin to spread apart. If you add heat, the particles do more 'work.' "Heat is work and work is heat."
500

If you cut an apple into slices, has the mass of the apple changed?

The mass has not changed. Even though it has been cut into pieces, if you put them back together, the mass would be the same as when you started!

500

If a glass of unsweetened tea has a mass of 225 g. If 15 g of sugar is added to the tea and stirred until fully dissolved, what is the mass of the glass of tea now? 

What is 240 g ?

500
Mr. Rogers has a pear with a mass of 60 grams and a volume of 40 mL. Will the pear sink or float? (Remember the math formula for density!)
What is sink? The pear's density will be 1.5 g/mL, which is more dense than the 1.0 g/mL of water.
