Activity | 1Scientific NotationPractice 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.TERMS Field properties Characteristics of a field thatDatabase file The file that contains all objects of determine how long an entry can be, how the entry will be formatted, whether there should be a default your database. entry, and what can be entered (for example, num- bers only or valid dates only).Datasheet A grid showing the data in a table, with Form A window showing the data in a table with one the field names as column headings and the records in rows beneath them. record’s fields appearing at a time in individually labeled boxes.Datasheet view The view of a table that shows Navigation mode A mode in which the entire field you the data in each record.

■ This row and column display is called Datasheet Switch between Views view. This view enables you to see more than one record at a time on the screen. ■ To switch to Datasheet view from Table Design view, click the View button on the Home tab (inDatasheet view displays data in rows and columns Access 2007) or the View button on Standard toolbar (in Access 2003) . ■ When in Datasheet view, the View button’s face changes, and clicking it switches you to Table Design view. ■ This button also has a drop-down list, so you can choose other views from it. Switch between Datasheet and Table Design views via the View button■ To move through the datasheet, you can use the navigation buttons at the bottom of the window.■ The navigation buttons also show the current record and the total number of records. You can type a record number in the specific record box and press Enter to move to that record.
