Assessment coming up!

August 20th, 2009 Mrs D No comments

During the first week of SEPTEMBER you can expect to be given an assessment on what we have covered so far in G9 Integrated Science.  That means all the stuff on variables, units, significant figures, errors, science apparatus.  We’ll talk more in class about this but here is a link to some powerpoints you might find useful.   Click through the first few introductory slides to get to the good stuff :)

Do you know what SI units are?

Do you know the SI units for length, time and mass?

Can you choose the appropriate number of significant figures to use in calculations?

The answers to these questions, and more, on this short video.
