CHAPTER 1 STUDY GUIDE

1.1

Science Technology

Scientific theory Scientific law

1. Know the branches of science and the divisions of each of the branches of natural science. (See p. 7).
2. Know the difference between science and technology. How do they work together? Know an example of how they work together.
3. Know the difference between a theory and a law.
4. Why might a theory be changed or replaced?
5. What is the difference between a qualitative and quantitative observation? Give examples of each.
6. What are some examples of models used in science? Why do we use models?
7. Know p. 12 #9. (NOT MY FAN EXAMPLE)

1.2

Critical thinking Length

Scientific method Mass

Hypothesis Volume

Variable Weight

1. Be able to put the steps of the scientific method in the correct order (p. 15).
2. Why is no experiment ever a failure?
3. Describe tools used by scientists that help them in their experiments.
4. Why do we use SI units?
5. What is the difference between a base unit and a derived unit? Give examples of each.
6. MEMORIZE YOUR CONVERSION FACTORS (order and prefix names)!!
7. For extra practice do p.867 a-c for Conversions.
8. Be able to match up length, mass, volume, and weight with the correct base unit and tool. (See notes)

1.3

Scientific notation Precision

Accuracy Significant figures

1. Know which type of graph is best for a given situation. (Trends… parts of whole…)
2. What are labeled on the X and Y-axes?
3. Be able to write a value in scientific notation. For extra practice do p. 866 a-f.
4. Why do scientists use scientific notation?
5. Be able to solve equations using scientific notation.
6. Be able to describe the difference between precision and accuracy. (Look at Figure 5 on p. 27)
7. Be able to count the number of significant figures in a value. (Atlantic/Pacific rule).
8. Be able to solve equations using the correct number of sig figs and the correct units.
