Simple Chemistry presents information and investigations on these six concepts:

• Objects can be described by the properties of the materials from which they are made
• Substances can exist in different states—solid, liquid, or gas
• Substances have characteristic properties
• Mixtures can sometimes be separated into the original substances using characteristic properties
• Elements are organized in the periodic table
• When substances react chemically, they can form new substances
