• Tues 9/4:  Questions on uncertainty and significant figures so far?  Instructions on how to propagate uncertainty through calculations and then do problems 21-25.  Characteristics of a good graph.  Instructions on how to use LoggerPro.  Each student should make one graph, either using the first set of data on the back of the hand-out or the 2nd.  I will initial your hand out when you show me your complete graph.  Turn in the completed hand-out if you are done today.  Otherwise turn in on Thursday 9/6.  Check your brine shrimp.  Bring TI-84 calculator or equivalent on Thursday 9/6.
