Google earth has many wonderful applications in the Mathematics Classroom. Here are some of the better applications. Please feel free to continue the list in the comments section below. I would like to credit Douglas Butler (www.tsm-resources.com) with some of the ideas below. www.googlecompass.com is also an excellent website for taking straight and angular measurements.
Bearings
|
Runway numbers are chosen based on the magnetic heading of the runway. In areas where the compass indication are unreliable the true north heading is, denoted by a T prefix. Example: Sydney Airport NS Runway is on a bearing of |
Plane Geometry
The Pentagon (US) – Is it a regular pentagon? | "Exmouth Cape Tourist Village" – (look slightly to the north) |
|
|
2D Measurement – To easily find the perimeter and area, you can use a Google Earth Add-on called GEPath. This can be used to check calculations.
Find the perimeter and area of your school. How big is your school oval? Most likely, it will be close to 1 Ha.

|
Have students create a field diagram (by taking measurements) to work out the area of the school, or their home. | Find the area of the sector below, by taking appropriate measurements. (This is at the Athletic Centre at Sydney Olympic Park). |
3D Measurement
|
|
Find the Great Pyramid at Giza – by taking appropriate measurements, what is the surface area and volume? (Its height is approximately 139 m). You can also show 3D Buildings to get a good look. | |
Parabolas

To the east of Lydd Airport, KENT, United Kingdom. See http://en.wikipedia.org/wiki/Acoustic_mirror for information on these fantastic structures! | |

More Resources can be found at www.realworldmath.org. I particularly like their complex area problem at http://realworldmath.org/Real_World_Math/Complex_Area_Problems.html. There are worksheets and KMZ (Google Earth Files) to download for many concepts. |
