Implementation Tips
This introductory lesson actually uses archived images, which will offer greater flexibility to prepare for the lesson if you are concerned about network failure, or cannot get into the computer lab.

If there are not enough computers for students, you could:

• create small working groups
• project the image for the class using an LCD projector
• print the map using a color printer

If the network is slow or not working, you could:

• print the color images on overheads and use the overhead project to project the images for the class
• print and photocopy the images, enough for small student working groups
• save data to disk
