Demonstrate the use of scientific notation within word problems. The lesson presents problems with large numbers best represented with scientific notation. Pupils use these numbers to solve the problems in the 11th installment in a...

Here is really nice set of resources on scientific notation. Eighth and ninth graders explore the concept of multiplying and dividing in scientific notation. In this multiplying and dividing numbers in scientific notation...

Apply the concept of scientific notation to a word problem involving the rate of speed. Sal explains how to express the answer using scientific notation.

This video contains additional scientific notation examples, continuing from the previous presentation. Viewers can see Sal work through several more problems using the techniques he has outlined throughout the pre-algebra video series.

Explaining scientific notation is useful because "it allows us to write large or small numbers in ways that are easy for our brains to write down and understand." Sal proceeds to solve a few practice problems involving scientific...

Scientific notation is defined and used to express the number 0.0000000003457. This concept is not as clearly defined as it could be, and is probably not suitable for those who have not had prior experience with the concept.
