Google+Earth


 * //Google Earth//**

In the "Fly to" search bar type your address. Use the navigation controls to home in on your house.
 * __How far do you live from school?__**
 * Use the Look joystick (top of the controls) to look around from one vantage point
 * Use the Move joystick (center of the controls) to move down, up, right or left
 * Use the zoom slider to zoom in or out (+ to zoom in, - to zoom out).
 * click and drag the ring aound the Look joystick to rotate the view.

Then look at the icons along the top of the map. Find the ruler icon and click. You then have two options Click the path option and choose the kilometers option Click on your house and then follow the route you take to school each morning. You may need to make lots of tiny lines if your path is not very straight. If you get to the edge of the map simply move the map across using the Move joystick (the one in the middle). Once you have reached HNPS the ruler will tell you the distance travelled and the red line will show your route.
 * line - is useful for drawing one straight line and measuring it
 * path - is useful when drawing a longer path that may not be all in one straight line

Could your class use this tool to work out the distance travelled when going on a class trip? If there are two routes to a destination could they calculate the difference between them?


 * __Other exciting features of Google Earth__**

Look at the icons along the top of the map again and find the one that looks like a clock. This can take you back in time. Home in on HNPS. Notice there is no library. These photos were taken a while ago. If you click on the clock a bar comes up and there is a little verticle line on the left hand side of the bar. It says October 7th 2003. Thats when these photos were taken. Hopefully they will update soon.

However we can use this tool to look at other areas around the world
 * The World Trade Center / Ground Zero - before and after September 2001
 * The Aral Sea, Russia. Water has been pumped out of the sea since the 1980s to irrigate the surrounding farmlands. See how the sea has shrunk over this time. Use your ruler to measure the difference.
 * Beijing - Look at the stadium built for the olympics. What did the area look like before the stadium was built?
