Mass |
The amount of matter in an object |
|
|
Volume |
The amount of space an object takes up |
|
|
Density |
The amount of matter in an object compared to the amount of space it takes up. |
|
|
Matter |
Anything that has mass and takes up spacemass |
|
|
Ice. That is why ice floats when it is in liquid water. |
Which has a higher density, ice or water? |
|
|
Heat, light, and ideas. They are not matter because they do not take up space. |
Give three examples of things that are not matter. Why are they not matter? |
|
|
A heavy object. |
What has more mass, a light object or a heavy object? |
|
|
Tiny particles. The more particles it has, the more mass it has. |
What is matter made of? How is it related to mass? |
|
|
A physical property because it is something that can be observed and measured. |
What type of property is mass? Why? |
|
|
Density. |
How can we show the relationship between mass and volume? |
|
|
By dividing its mass by its volume |
How do you find the density of matter? |
|
|
Color, shape, and texture. |
Give three examples of physical properties. |
|
|
Your senses. |
What can you use to detect physical properties? |
|
|
State of matter |
One of three forms (solid, liquid, and gas) that matter can exist in. |
|
|
Solid |
The state of matter that has a definite shape and a definite volume. |
|
|
Liquid |
The state of matter that has a definite volume but no definite shape. |
|
|
Gas |
The state of matter that has no definite shape or volume. |
|
|
Particles in solids are tightly packed. They are too tight to move around. They just vibrate. |
How are particles in solids arranged? How do they behave? |
|
|
Particles in liquids are packed more loosely than solids but tighter than gases. They slide around causing the liquid to take the shape of its container. |
How are particles in liquids arranged? How do they behave? |
|
|
They are loosely packed. The particles bounce around and spread out. |
How are particles in gases arranged? How do they behave? |
|
|
Heat makes the particles move faster. The particles begin to slide around and the solid becomes a liquid. |
What happens to particles when an object is melted? |
|
|
The volume stays the same, but the shape changes |
What happens to a liquid if you pour it from a round container to a square one? |
|
|
Particles slow down until the gas condenses, and the gas becomes a liquid. |
What happens to gas particles when it is cooled down? |
|
|
32 degrees Fahrenheit |
At what temperature does water freeze? |
|
|
212 degrees Fahrenheit. |
At what temperature does water boil? |
