We are all familiar with Google as a means to search the internet.
What you may not know is that Google offers a far wider range of applications and resources, many of which are designed to be used in schools.
You can find an introduction to what they offer here.
You will find lesson plans, tutorials, tips on using Google Earth in class and the chance to share information with other teachers.
The main focus seems to be on the Humanities at present but hopefully other resources will follow.
