        Scientific Notation

        Practice Activity

                     Technology Overview             A database program is a useful tool in which to
                     store and organize large amounts of data.You can even perform calculations with the
                     data. In this activity, you will edit a database by adding information you locate on the
                     Internet. Then, you will convert the numeric data into scientific notation. Finally, you
                     will create a report of the information.
                     Content Overview           Scientific notation is a method of representing a num-
                     ber as a decimal between 1 and 10 multiplied by a power of 10. It can make numbers
                     that are very long much easier to write and work with. In this activity, you will convert
                     the atomic masses of several elements from the periodic table into scientific notation.

        Data type The type of data that a particular field is
           designed to hold. Common types include Text,     Navigation Pane The listing of all the objects in
