Sig figs, conversions, graphing

All the fun of significant figures and conversions without any of the calories! (updated 6/27/22)

  • Takin’ Data:  A general overview of the topics in the tutorials below.
  • Significant figures:  Chemistry teachers like to write “sig figs” on papers before writing “-1.”  Find out how to avoid this fate by learning about significant figures, precision, and accuracy.
  • Significant Figures PPT:  Another explanation of significant figures for those of you who love slides.  I don’t go over calculations here because I’ve come to the conclusion that they’re not all that important to know until you hit AP Chem.  Your teacher may disagree.
  • Calculations involving significant figures:  For those of you who are fans of addition, subtraction, multiplication, and division, here’s a little something for you to enjoy.
  • Units and conversions:  Learn about SI units and how to convert between them.  It’ll be fun!
  • Units (PowerPoint):  Learn about SI/metric units, how to convert between them, and what the deal is with all those prefixes, all in handy PowerPoint form.
  • Drawing good graphs:  If you’re drawing a bar graph, hang your head in shame.  If you want to learn how to make a graph that will get published in the finest scientific journals (i.e. your lab book), read on!
