Scientific+Notation

=Title: Size it up! = =Big Idea: Using scientific notation in real world application = =Objectives: __Students will be able to:__ =
 * 1) == Convert between standard notation and scientific notation of small and big numbers. ==
 * 2) == Discover how to write small and big numbers in formats other than scientific notation. ==

=Standards:=

Math: 7th Grade Standard 1 (Number Sense)
=Background Knowledge:= == Students need to have basic knowledge of numbers. They need to be able to: recognize place value, read numbers, and write numbers. Students need to know that each place you move the decimal to the left is dividing by ten each step. Students need to know that for each place you move the decimal to the right is multiplying by ten each step. They need to know what a power or exponent is. == =Materials:=

Computer with internet access, IPad, paper and pencil
=Procedure:= =Extension:=
 * 1) == Begin class by review scientific notation, how it is written, and the components. Put some problems on the board to practice. It is important that students do not just count zeros. ==
 * 2) == Students need to collect information with big or small numbers (size of cells/organelles, distances in space). On the IPad, NASA and the Cell Stain apps give measurements for these items. Students could also use their science book or other sources in the classroom. ==
 * 3) == Students need to write down at least 4 big distances in space (from what to what) and 4 small distances relating to cells, bacteria, viruses, etc. ==
 * 4) == Students need to try and convert the measurements into scientific notation. If the measurements were already in scientific notation, then they need to put the number back in standard notation. ==
 * 5) == Students can then use the calculator app to check if their answer was correct or not. ==
 * 1) == Students can convert the large distances into astronomical units (AU). ==
 * 2) == Students can rewrite the smaller units in microns. ==
