Part B
Gather all of your pennies dated before 1982. Then follow the steps to complete the table. Include units as necessary.
Record the number of pennies dated before 1982.
Weigh (as a group) the pennies dated before 1982. Record the total mass. If you’re unfamiliar with using an electronic balance, watch this video before continuing.
Calculate and record the average mass of a single penny. If you need help with the calculation, visit the averaging data section of the math review.
number of pennies: 8
combined mass of the pennies (g): 49.2
average mass of a penny (g): 5.525
Part C
Now gather all of your pennies dated after 1982. Complete the table for the post-1982 pennies using the same steps from part B.
number of pennies: 9
combined mass of the pennies (g): 51.7
average mass of a penny (g): 5.744
Part D In parts B and C, you measured the average mass of each group of pennies. Now you’ll measure their volume. (For this part, assume that the pennies dated before and after 1982 have the same volume.) Follow the steps to complete the table. If you’re planning to use a graduated cylinder, watch this video on measuring volume before continuing.
Stay safe! Be careful when handling glass containers so they don’t break.
Add water to the narrow transparent container until it is about half full.
Stick a piece of tape to the outside of the container to mark the water level. The water level must be even with the top edge of the tape.
Using a graduated cylinder or a teaspoon measure, add another 5 mL (1 teaspoon) of water to the container. Be sure your measurement is exact.
Stick another piece of tape to the outside of the container to mark the new water level. This time, the water level must be even with the bottom edge of the tape. Your setup should look something like this.
Next, remove 5 mL
