Section 3: Scientific Notation

Concepts

This section explores the format, rules, and process for expressing numbers in scientific

notation. The standard form for scientific notation is given. Then, the process of conversion

from standard decimal notation to scientific notation is modeled, with an example, to

demonstrate the process. The calculator representation of scientific notation is shown.

Finally, the four basic arithmetic operations for numbers expressed in scientific notation are

shown, step by step.

This topic assumes that students understand the concept of significant digits covered in the

previous section (Precision & Accuracy).

Activities—DecimalÆSci-Not, Sci-NotÆDecimal, Arithmetic

These activities provide students with practice in scientific notation. For each of three activities,

ten conversion problems are presented (the order varies each time).

correct answer on the first try, 10 points on the second try, up to a maximum of 200 points. Tell

students if you wish them to record their scores and if they can repeat the activity to improve

their scores.

After each problem, students can select

to try another problem. At any time they can

select
