media type="custom" key="5726739"Chemistry Units: Scientific Notation Scientific Notation is a simpler way to use and display numbers that would become messy and cumbersome otherwise. Following is a short look at what they can simplify - imagine what trying to add or multiply such big numbers would look like...

Grade Level: 10-11 Unit: Chemistry Lesson Objectives: Time Required to complete this lesson: 1 week Title of lesson: Scientific Notation Description of lesson: Students will manipulate large numbers for a while, without SN, in order to facilitate their capture of the need for it. We will practice writing them. Then adding and subtracting them, before using multiplication and division on them. There is a lot of practice that must be done to make its use and correct use habitual. Please, no skipping. Assignment: Practice quizzes and assignments, though somewhat simple, will be many. Resources/materials needed: Some online learning tools will be used. But most should be done by hand and mind – not calculators and especially not engineering or scientific calculators (yet). Technology used: We will use the online learning tools to keep the practice from getting dull. The technology used in this lesson changes the teaching / learning in this way: Maintaining interest levels helps even rote become bearable.
 * Student will understand why Scientific Notation is useful
 * Student will be able to use scientific notation to record and manipulate numbers
