This is a 16 slide PowerPoint that also has activities that the children do along with the slide show. There is even a quiz at the end that has a built in control of error (sound). The children will enjoy creating the land and water forms with clay and a spray bottle of blue-colored water. It includes lake/island, cape/bay and system of lakes/archipelago. I usually have the children work in pairs with a dual headphone adapter. They work on the computer with a nearby table for activities.
