Vocabulary
Small structures that make up all matter. These are also known as Atoms.
Particles
This state of matter has a fixed volume and shape. The particles tend to stay close together and not move very much.
Solid
This property can be identified, observed, or measured, but it doesn't rely on testing to see if the material reacts with another substance
Physical Property
Two or more atoms held together by chemical bonds
molecule
The basic building block of matter
atom
The total energy of motion of the particles, often referred to as heat
Thermal energy
This state of matter with no fixed shape. The particles have a lot of movement and do not stay grouped together.
Gas
How a material reacts with another substance
Chemical Property
Most elements are at what phase of matter at room temperature
Solid
What happens to the kinetic energy of a liquid when the temperature drops
The kinetic energy decreases
The simplest pure substance
Element
This state of matter has a specific volume but not a specific shape. The particles tend to stay close together but can slide past one another.
Liquid
Name an example of a physical property
(answers will vary)
Can be identified, observed, or measured.
True or False: The particles in a solid are very close together and can move throughout the whole solid.
(if false then why)
False
They CAN NOT move throughout the whole solid
An element contains _____ kind(s) of ______.
An element contains one kind of atom.
Define Material
A type of solid used to make things.

Define Extended Structure
A varied number of one or more kinds of atom bonded together to form a large network.
Draw atoms/particles in the state of a liquid.
Your atoms/particles should be close together, disorganized some touching and some not touching.
