Intro to CPE Science and Motion Ch 10
Indicators:
SI-A1. Distinguish between observations and inferences given a scientific situation.
SI-A2. Research and apply appropriate safety precautions when designing and conducting
scientific investigations (e.g., OSHA, Material Safety Data Sheets (MSDS), eyewash,
goggles and ventilation).
SI-A4. Decide what degree of precision based on the data is adequate and round off the results
of calculator operations to the proper number of significant figures to reasonably reflect
those of the inputs.
SI-A5. Develop oral and written presentations using clear language, accurate data, appropriate
graphs, tables, maps and available technology.
SI-A6. Draw logical conclusions based on scientific knowledge and evidence from
investigations.
For this unit, we will be focusing on scientific processes like designing
experiments; recording and reporting results; communicating results; making
accurate measurements; and using correct units and number of significant figures.
We’ll do this by reviewing some of the things you learned about motion last
year…speed, velocity, and acceleration, both mathematically and graphically.
In the end there will be two assessments. One is a mixed format test (multiple
choice, short answer, problems, and graphs) as well as a lab report that you type up.
