- Matter is anything with mass and weight
- Define substance, element, and atom.
- Substance is matter that is made up of elements
- Elements are something that is not man made, they come straight from the earth or from space. They cannot be broken down.
- An atom is the smallest measurement possible.
- Define mixture, homogeneous, and heterogeneous.
- A mixture is two or more of anything put together.
- Homogeneous is a combination of two or more things. Homo - Different
- Heterogeneous is when two or more substances can be separated.
- Explain the difference between mass and weight.
- Mass is the amount of space it takes up.
- Weight how much it is affected by gravity.
- Explain the difference between a physical and chemical property.
- Physical property includes how it looks and how it smells. Anything to do with its appearance
- Chemical property includes how hot it takes it to catch fire or for it to melt.
- Explain the difference between a compound and a mixture.
- A compound is two or more elements put together.
- A mixture is many elements put together.
- Describe the process of distillation.
- Distillation is separating compounds from liquid using select condensation and evaporation.
- Provide an example of a gas-gas, liquid-liquid, and solid-solid mixture. Label each mixture as homogeneous or heterogeneous.
Liquid-Liquid = Gasoline-homogeneous
Solid-Solid = Metal alloys-homogeneous
