This lesson covers the basic problems with the standard Mercator projection map that is used all over the world. It asks pupils to answers questions, first with a Mercator map and then using data. It shows how the scale of the mercator map is quite distorted near the poles and how the Peters projection gives a more realistic view of the land surface of the Earth. My pupils found this a very interesting lesson - a real wow at the end of it. Hope that it is useful.
