Chemistry Pennium Lab

Questions

    1) Does each penny have the same mass?

    2) Can you identify two "penny isotopes" based on masses of the pennies?  Explain.

    3) What does your data tell you about the relationship between mass of a penny and date of a penny.  Make a generalization.

Hypothesis

   -We believe that you will be able to identify two different pennies because pre-1982 & post-1982 are made with different materials, so they both have different masses

Materials

    1) 1 bag of pennium atoms

    2) Fivecentium

    3) Dimeium

    4) Quarterium
    5) Halfdollium

Procedures

1. Obtain a packet of pennies.
2. Sort the pennies into two groups: pre 1982 &  post 1982
3. Measure the mass of each stack of pennies. Record the mass of each penny stack in a data table. Count the number of pennies in each stack.
4. Measure the mass in grams of a quarter, nickel, and dime. Record these values in a data table.
5. Determine the mass of pre-1982 pennies
6. Determine the mass of post-1982 pennies

                                          DATA:

Conclusion

 We accept our hypothesis because all of the data proves what we decided.
