100
What makes some Matter?
It has mass and takes up space
100
Name the three states of matter
Solid, Liquid, Gas
100
What unit do we use to measure small masses like a paper clip?
Grams (g)
100
What is Density?
How much mass is packed into a certain volume
Dense city = Mass-achusetts
100
I have mass
I take up space
I can almost always be touched
Matter
200
Name one thing in the classroom that is matter?
Desk, chair, book, air, pencil, etc.
200
Which state of matter has particles packed closely together? Draw it.
Solid
200
What unit do we use to measure liquids like a juice box?
Milliliters (mL)
200
In our density lab which liquid stayed at the bottom of the cup?
Honey
200
I take the shape of my container
I can be poured
I was in a measuring cup
A liquid
300
Even though we can't see air, how do we know it is matter?
It has mass and takes up space (balloon example)
300
Which state of matter has particles that move freely in all directions?
Gas
300
How many mL are in one liter?
1000mL
300
Why does air change volume when you squeeze the syringe?
Air particles have lots of space between them
300
I am invisible
I can be compressed
I still have mass and volume
Air
400
Give an example of something that has volume, but is hard to see
Air in a balloon, air in a tire, air in a room.
400
Describe how particles move in a liquid.
They are close together, but can slide past each other
400
Give one example of something measured in grams AND one meaasured in Kilograms
Grams: Pencil
Kilograms: Bag of flour
400
Why did the liquids in our lab form layers instead of mixing right away?
Because they all had different densities
400
I floated at first in the drink
I am a solid
I was less dense than the liquid around me
Ice Cream
500
Explain how you could prove air is matter using an experiment or example.
Inflate a balloon, feel air resistance, show it takes up space and adds mass.
500
Compare particle space and movements in solids, liquids, and gases. Draw it out.
500
Explain why Scientists use SI units instead of making up their own?
So measurements are accurate, consistent, and understood everywhere.
500
Using particle spacing explain why ______ are the least compressible
Solids; solids particles are tightly packed with almost no empty space to reduce
500
I made bubbles appear in the drink
I am a gas
I escaped as bubbles wehn the ice cream was added
Carbon Dioxide
