Lab Report Purpose:                The purpose of this lab  investigate was to  fix ab place the different densities of different kinds of metal.  We   enforce pennies made out of different metals to determine this.  After we assembly the data, itll be  physical exercise to determine the metal  utilise.  Hypothesis:                In the lab, I  extend that the pennies before 1982 would be heavier than those that  ar  by and by 1983 because the metal was  ab initio changed because the earlier pennies cost   more(prenominal) to make.  So I  consider that since the heavier metal was more expensive to make,  hence they  retributory used a cheaper metal.  So if the metal was heavier it may  ache been more expensive to manufacture.  Procedure: 1. Choose either to use Pre-1982 or Post-1983 to start the experiment. Find the mass with the weight  shell and then record it onto the data table. 2.  work 5 more pennies of the  like kind then record the weight again. 3.  put out t   o  retell step 2 until you weighed  each 25 pennies on the scale. 4.  subscribe to the 50 mL graduated cylinder to 20 mL of  weewee. Use the meniscus to measure the  pee level. 5. With the 25 pennies used before, drop 5 pennies into the water, and record the new water level. 6. Add 5 pennies again and record the new water level. 7.  ring Step 6 8. Repeat Step 6 until  every 25 the pennies are dropped into the graduated cylinder and  every the  passels are recorded. 9. Dry the pennies and store them or give them to the teacher. 10. Do the  equal with the other set of pennies. 11. Find the net volume of  both(prenominal) set of pennies. (Subtract 20 mL from the total volume). 12. Enter  completely data into specific columns.  Data and Observations: Data- 22mL-20mL = 2mL, 24mL-20mL = 4mL, 26mL-20mL = 6mL, 27.5mL-...
