Tomorrow you will be performing your first "official" laboratory experience for a grade. Your only expectation for preparing for the lab is to write a Purpose statement for the lab and to also write a Theory statement. Remember, you are going to try and confirm if the minting (manufacturing) process for pennies changed in 1982. You are going to use the physical property of density to distinguish the different categories of pennies. Since you will be measuring in this lab, you MUST incorporate precision and accuracy of measurement and proper use of precision and significant figures in calculations. The validity of your results depends upon it.
**Extra Credit Opportunity** If you bring in a 4-pack of AAA batteries, you will receive 10 points extra credit towards your homework portion of your grade. The purpose of me (Mr. Brueckner) stockpiling batteries is two fold. First, it supplies the calculators that I allow students to use in class with batteries. Second, it provides a stockpile of batteries for any and all students enrolled in any of my classes to have a source of batteries if the batteries run out in a student's personal calculator. Remember, I do not offer extra credit on an individual basis, so take advantage of any and all extra credit opportunities when offered. You can bring batteries in through September 3rd. Have a good night.
