GRADE 7 PROPERTIES OF MATTER

At the conclusion of this unit you will understand that…

• Matter is identified by its characteristic properties.
• Mixtures can be separated into individual parts by using characteristic properties.

Inquiring scientific minds will be able to answer these essential questions...

• How can characteristic properties be used to identify parts of a solution/mixture?
• How can physical processes be used to separate parts of a mixture?

Key Scientific Concepts/Vocabulary…

chemistry	mixture	solution	acid	base (alkaline)
solute	solvent	solubility	dissolve	insoluble
soluble	freezing point	boiling point	evaporation	desalination
distillation	concentration	volume	dilute	density
physical properties	matter	quantitative	qualitative	archimedes
mass	temperature	saturated	chromatography	pH
heterogeneous	homogeneous	state	neutral	universal solvent

Young chemists will be able to….

· Analyze samples by quantitative methods.

· Use the appropriate processes to determine density and other characteristic properties.

· Select appropriate lab equipment.

· Demonstrate safe and appropriate use of lab equipment.

• Effectively communicate results.
