Unit 1 - Science Skills and Introduction to Matter

Objective 1 - Review of scientific method (due 9/11)

Essential question - How do we use the scientific method?

Learning targets -

1) Define the following:

• Hypothesis
• Theory
• Law
• Variable
• Control

2) Why do we need controls in experiments?

3) Why is repetition required in experiments?

4) What does it mean for an experiment to be replicated?

5) How are theories and laws different?

6) What qualifies as a "source of error" in an experiment?

Objective 2 - Matter, mass, and volume

Essential question - How is matter described in terms of mass and volume?

Learning targets -

1) Define the following:

o Matter

o Mass

o Volume

2) Give appropriate units for mass and volume

3) Measure mass of an object using a balance (already done in class)

4) Relate the volume of a container (in cm³) to the volume of the liquid it contains (in mL)

Objective 6 - Density

Essential question - How is density used mathematically?

Learning targets - (italics should be in your notes)

1) Define: density

2) How can density be used to identify unknown substances?

3) Given a graph of mass vs volume of a substance, write the equation of the line and state the meaning of the slope (in class)

4) Use density as a conversion factor between mass and volume (in class)
