As you tour you will see yellow circles. Click these and a variety of things may happen:
You may see the name of the room you are in and its purpose
You may link to a video of children talking to you about the school
You may link to a video of the class teachers telling you about their class and year group (these links are on the tv screens/smart boards in every classroom.
You can tour in two ways - by touring around room to room or by clicking on the Dolls House (icon on bottom left of screen). You can then locate an exact place in the school and go straight to it. This approach also shows all the yellow circles.
