Collected Graphs and Data Tables for Measurement of Round Objects Lab

Covered "Skills Needed In Physics":

Dealing with BIG and small numbers

Scientific notation and using your calculator: Use the EXP or EE key, 2 x 10^2 is NOT the same as 2^2 so be careful with notation and don't take shortcuts.
Be careful when entering numbers into your calculator: 10^5 = 1 EE 5 and not 10 EE 5
Went over prefixes - students must memorize the basic ones (nano, micro, milli, centi, kilo, mega, giga). Did prefix worksheet in class.
Watched "Powers of 10" video

Went over unit conversion explanation sheet. Students worked on unit conversion worksheet in class - just getting the correct answer is not sufficient - students MUST show the proper strategy. Students checked answers against answer sheet.

Homework due Tuesday: handed out worksheet on scientific notation and algebraic manipulations.

Also handed out Abstract Reasoning worksheet. I will expect students to get at least 5 of these correct. Five correctly answered problems will earn full credit, more than five correct will earn extra credit. I will collect this sheet on Friday - no late work will be accepted for this sheet.
