3. Key Points: -Pace determines how quickly you complete the course. -Track tells if you are doing regular credit or advanced credit. - Question: How long does it take to finish the course (S1 and S2) with the traditional pace chart? What is different about the advanced track?

4. Key Points: -Science is many things *a body of knowledge *a way of finding out about the world around us -Scientists have many shared characteristics: *curious *open minded *don’t give up easily *willing to learn new things - Question: Who can be a scientist?

5. Key Points: Scientific Laws describe an observation. *cannot be broken Scientific Theories try to explain the observation. *they are supported by many years of experimentation and data *they can change if new data is discovered Question: What’s the most usual reason for a theory to be changed? A scientific theory is just a guess. True or False?

6. Key Points: -Scientific Method is a process used in science. *Purpose – What you are trying to find out. *Hypothesis – Prediction about your purpose. *Experiment – Test designed to answer the purpose. (Data is recorded as well). - variables – the things that are changed - constants - the things that do NOT change *Analysis – Review and compare data from the experiment. *Conclusion – Determine whether the hypothesis is true or not. Questions: What are some other ways that scientists can investigate other than doing an experiment? What are some reasons that might explain why a scientist got different results when an experiment was repeated?
