Hi! I'm a Chemistry student currently undergoing corrections for my IA draft. I just really really REALLY need help on what the points to IB grades are. For example, how many points do I need to score from the overall rubric in order to barely reach a 7? How about 6? and so on and so forth. Thanks!
Hey all! I have a question on scale calculations for scientific diagrams. In my classroom, we used a calibrated reticule to measure a cell length, lets say a value of 1.234mm If my diagram length was 12.34cm, what precision do I use? Scale for the assignment is to be shown as size of diagram:size of object in cm : micrometers In this example the final scale value as 1.00cm= 10.00 micrometers after calculating scale: (1.234mm) / ( 123.40mm) = 0.01000mm x 1000 = 10.00 micrometers ->> 10.00 micrometers follows sig figs, however, is not the measured precision of the reticule at 0.001mm. So my question is, are these precisions of decimal places correct? And do you follow sig figs or original precision when showing scale?
