All Mixed Up
Investigate substances, mixtures, and ways to separate materials based on their properties.
How can we use the properties of matter to separate a mixture into its individual components?
Key Vocabulary
Mixture
A combination of two or more substances that are not chemically joined together.
Solution
A mixture where one substance dissolves completely in another.
Filtration
Separating solids from liquids by passing through a filter.
Evaporation
The process of a liquid turning into a gas, leaving solids behind.
Physical Property
A characteristic you can observe without changing what the substance is made of.
Magnetism
A property of certain materials that allows them to attract iron and steel.
Key Concepts
- 1
Mixtures can be separated using physical methods because the substances keep their original properties.
- 2
Different separation methods work based on different physical properties like size, magnetism, and solubility.
- 3
Scientists choose separation techniques based on the properties of the materials in a mixture.
- 4
Not all methods work for every mixture — you need to match the method to the materials.
