Writing in Scientific Notation  (Kmz)

Objectives

1. •Measure distance between two points
   

2. •Write large numbers in standard form to 3 significant digits
   

3. •Express large numbers in Scientific Notation
   

Lesson Description

This is an introductory lesson to teach students how to write large numbers in scientific notation.  The values used are found by measuring the centimeter distance between pairs of cities from around the world using Google Earth’s ruler tool.

Writing numbers in different forms becomes increasingly important to students in the middle years.  In this activity, the students will first express the numbers in standard form using 3 significant digits, thus, 53,284,967,018 becomes 53,300,000,000.  Next this value is written in scientific notation: 5.33 x 10 to the 10th power.

Video instructions are given to students in a brief tutorial as they climb Mt. Everest.  This is included in the Google Earth folder using Xtranormal (or YouTube) video links in the first 8 placemarks.  An internet connection is necessary to view these.  In addition to the Google Earth Kmz of the activity, an activity sheet and answer sheet are also included below for download.

The Scientific Notation 2 lesson can be used as a follow up for this lesson.  It uses numbers written in scientific notation to calculate products or quotients.

Notes: 

1. •Xtranormal clips aren’t playing in the latest version of Google Earth.  so I’ve included YouTube clips in the first download below.  That should work.
   

2. •I’ve added a Ruler Demonstration with the YouTube version of the Kmz file.  It is also included with the Downloads below as a Placemark file and as a link.  You can view the video below.
