  • scientific notationWith the student review the following vocabulary: scientific notation
  • Review with student the reason using scientific notation is important. (It lets us write very large and very small numbers without using a lot of zeros.)
  • Together with the student try changing a large number into scientific notation.  For example, the mass of Pluto is 1,250,000,000,000,000,000,000,000 Kg.   What will this look like in scientific notation? (Answer: 1.25kg x 1022)
  • Provided the student understands this concept, have them independently change the mass of the Moon from 7,390,000,000,000,000,000,000,000 into scientific notation. 
  • The student should complete the Scientific Notation Worksheet using the media of his/her choice.  (Question number 5 could be completed as a homework assignment or to continue the lesson onto another day.)
