Week 8 - Matter (Part 3)

Introduction to Matter

Learning Target: I can explore chemical and physical changes.

Warm-Up (9/30/20)

1) If you were to mix two substances together what might be some things to look for to see if there is a chemical reaction taking place? List them.

2) If you were to shrink yourself down to the size of a molecule what should you see happening during a chemical reaction?

3) Which chemical property can only be determined by observing harm to living things?

Property - a measurable quality that can be established only by changing a substance's chemical identity

Molecule - two or more elements joined together by a bond

Chemical Property - any of a material's properties that can be established only by changing that substance's chemical identity.

Physical Property - any observable property that is measurable, without a change in the substance.

Chemical Change - a chemical reaction that results in the formation of at least one new substance.
