The clouds in the sky

The children go on a trip to the mountains with their two monitors Colin and Cathy. While they are outdoors they learn how to identify the different shapes and sizes of the things ther see around them. The paths are long and they bend, the sun is a big circle in the sky, their tents look like small triangles when they observe them from the mountain top and even the clouds have different shapes. Maybe you have seen animal shapes and different objects flying in the sky too.
