"Homework" For Next Class

You should have a digital representation (word document, powerpoint/prezi, etc.) that communicates the following associated with your experiment determining the "best" glassware to measure with:

  • Goal - state the goal of the experiment.
  • Materials/Equipment list - what did you use to perform this experiment (i.e graduated cylinder, pipette, etc.).  Pictures would be helpful, but not necessary.  You should be specific (i.e. instead of graduated cylinder, you would write 100 mL Graduated Cylinder).
  • Procedure - Step-by-step list of instructions that explains the steps necessary to collect the data for this experiment.
  • Data - Organize your data in a table or tables.  The key here is organize.
  • Calculations/Results - You need to perform the following calculations with each data set (i.e. for each piece of glassware) 
    • Average Volume of Water Measured
    • Percent Error (using the value from the glassware as the accepted value; the value from the scale, in mL, is the experimental value)
    • Mean Absolute Deviation (MAD)
You must be able to show me ONE example of each calculation in your write-up, but you still need to calculate the above for each data set.  You will list the ANSWERS TO ALL CALCULATIONS in a RESULTS table.  Results are answers that are calculated.  So you should have a table that provides the Avg Volume, %Error, & MAD for each piece of glassware.

*note - I have created a new page at the top of the blog titled "screenshots" to highlight things that happened during class.  You can find the notes from the board here.

This is what you need for Monday.  Come see me for any clarification.
