Unit 3, Lesson 1: What is matter made of?
You can't see air around you, but it is made up of _________________ which has weight and takes up ______________________.
matter/particles space
The particles in a solid have a ___________ volume and shape.
fixed
Odors, such as baking cookies, reach your nose through the air. Particles of food that are too small to see _____________ through the air.
float
The material dissolved in a solution is not _____________________.
gone
What matter has neither a fixed volume or a fixed shape?
A gas.
What matter has a fixed volume, but not a fixed shape?
A liquid.
What matter has a fixed shape and volume?
A solid.
What is matter?
Anything that takes up space and has weight.
Name some examples that show trapped air.
Balloon, soccer ball, basketball, and bounce house.
All matter is easy to see. T/F
False, air is matter and it is not easy to see.
What happens when a material dissolves?
It mixes completely with another material and forms a solution.
What tool can you use to see tiny particles?
Microscopes.
You can describe the state of matter by describing how the particles are _________________________________.
Moving/arranged.
Can odors be smelled in all parts of the room at once?
No. Odors are made of particles that move freely and they will take time to travel to all the parts of a room.
What are smaller pieces of matter called?
Particles. We know that particles are made up of atoms and molecules.
What are the three common shapes of matter?
Solid, liquid, and gas.
Why does a blown up balloon weigh more than one that is not blown up?
The air adds weight to the blown up balloon.
When a material __________________________, it mixes completely with another material and appears as just one material.
dissolves
How do particles in a solid matter move?
They vibrate in place.
How particles are arranged and how they move change their volume and shape. T/F
True
Will a drop of sugar water solution have the same amount of sugar from a spoonful at the top as at the bottom?
Yes, in a solution the material mixed is same throughout the solution.
What does the word fixed mean?
not changing
Sugar dissolved in water will reappear when the water turns into vapor. It is the _____________________ sugar that was dissolved to make the solution.
same
Liquid particles are always ___________________ past one another like marbles in a bowl.
sliding
When the particles of one material are dissolved with the particles of a different material, the mixture is called a ______________________.
solution
The particles in a liquid have a fixed _____________, but not a fixed shape.
volume
The particles in a gas spread apart and move freely in all directions. A gas does not have a fixed ______________________ or a fixed _______________.
volume/shape
