Scribe post for Friday, Oct. 19th

Hey guys! Sorry it took me a while to scribe, but it's the weekend so no worries.
Well, we started our new unit in class on friday, Significant Figures. We got a few worksheets on the rules, information and practice questions.

Some tricky ones (I found were tricky at least..) was..
1) 3.007 km
that zero is significant because it is between two significant figures (3 and 7)
* rule: zeros between two other significant digits are always significant
2) 819 000.0 g
this measurement has seven significant figures
* rule: all final zeros after the decimal point are significant
3) 60 000 x 10³ g
this measurement has only 1 sig fig.
* rule: zeros used only for spacing the decimal point are not significant

We also did some practice on sig. figs with mathematical calculations. Takes some extra thinking but we'll get used to it ... Oh and we also did some unit conversions.
That should pretty much cover the class... Test tomorrow! (Monday) Study hardy! Good luck everyone :)

Oh yeah scribe ... (WOW they'll have an easy scribe, just say we had a test?) Is ... um.. hanz?
