I discovered this neat little network link Google Earth file via Frank on the Google Earth Blog. I think it will be a useful teaching aid for Science.
It shows the leaf colour of major forests in and around the UK, the information is gathered from the Forestry Commission sites and transposed into Google Earth. The colours will change as the Autumn season progresses.
In class we are soon to be looking at life processes in Science so I will be keeping an eye on this one. I thought I might take a snapshot of Google Earth with this network link on, like the image above and watch it in a Flickr slideshow with the fade on or in Picasa with similar fading settings to illustrate to the kids the changing colours of this time of year.
