All living and non-living things are made of this.
What is matter?
100
The amount of matter an object has is called this.
What is mass?
100
This type of change does not change the particles that make up matter. Breaking a pencil, ripping a sheet of paper, and creating a bowl out of clay are all examples.
What is a physical change?
100
To find the density of a substance, divide its _______ by its volume.
What is mass?
100
A _______________ is made up of substances that are combined but can be separated. Examples include salad, trail mix, and lucky charms.
What is a mixture?
200
Color, size, shape, texture and odor are all examples of this.
What are properties of matter?
200
You can use this tool to compare a mass that you know with a mass that you don't know. The measurement unit is grams.
What is a double pan balance?
200
This type of change produces a completely different kind of matter.
Rust, tarnish, and burning wood are all examples.
What is a chemical change?
200
When liquids form layers, the substances with the __________ densities are located near the bottom of the container.
What are the greatest densities?
200
A mixture in which one or more substances are dissolved in another substance is called a _________________. Koolaid is an example.
What is a solution?
300
This state of matter has a definite shape. Its particles are closely packed together and have some energy. They move back and forth but do not change places with each other.
What is a solid?
300
You would use this tool to determine if you need to wear a jacket to school. The measurement unit is 'F or 'C.
What is a thermometer?
300
When you freeze water into an ice cube and then let is melt....this has occurred.
What is a phase change?
300
The amount of mass in a certain volume of matter is called this.
What is density?
300
Anything that has mass and takes up space is ___________.
What is matter?
400
This state of matter does not have a definite shape. The particles are not held together as tightly as in a solid. They are able to slide past one another.
What is a liquid?
400
Liquids do not have a definite shape. In order to measure their volume, you would use this measuring tool. The unit is mL.
What is a graduated cylinder?
400
A mixture is a type of this change because the particles do not change and can be separated.
What is a physical change?
400
When liquids form layers, the substances with the __________ densities are located near the top of the container.
What are the least densities?
400
When most liquids are cooled to the freezing point, the tiny particles of matter that make up the liquid:
(a) move quickly in all directions
(b) move out into the air
(c) come closer together
What is (c)?
500
This state of matter takes the shape of its container. Unlike a liquid, it will always fill the container it is in. The particles are very far apart from one another and move in all directions.
What is a gas?
500
The amount of space taken up by matter is called this.
What is volume?
500
This can cause the particles in a substance to move faster and farther apart. Substances change phase when enough of this is added or taken away.
What is heat energy?
500
An ice cube floats in water because the density of ice is ________ than the density of water.
What is less than?
500
You make a solution when you mix:
(a) salt and water
