Can you predict the changes in temperature of the surface water of the Great Lakes? This activity will have participants examine satellite images and collect data. Please feel free to use the activity while on-line.

If you decide that you want to use the activity with a class or group, please use software such as WebWhacker (Mac or Win) to download the entire activity.  You can also order the CD-ROM - GLSeeker which has this activity (older version - images are larger and more detailed) and many more activities, software and resources about the Great Lakes for $10 from Ohio Sea Grant Publications.

By downloading, you will have the entire set of material needed for the activity and you will not have to wonder if you will have access to the activity at the time you want to use it.

Updated version of the original activity.

Updated version using a quicktime movie showing the changing temperatures over a year. The movies are large 10-20 meg. If the version of browser does not recognize and play the movie, you may have to edit the application settings (under preferences) to recognize the suffix (qt) used by these movies.
