Read the Syllabus found on blackboard under Course Documents (there will be a quiz!) Objectives • To review SI units, Prefixes, Accuracy and Precision, and Rules for Significant Figures • Students will practice: • • • • conversion between units proper use and recognition of prefixes differentiate between accuracy and precision Practice calculations using significant figures Safety For this week, there is no requirement for goggles, pants, shirts, or jewelry – but be careful while in the laboratory. Complete the procedure at home and come to lab prepared to ask any questions that you may have. Labs will meet long enough for TA to take attendance and answer any questions regarding the lab: BE ON TIME!
