I chose the spherical earth as a basis for teaching a lesson to young children. I really like the ideas in the module. Children are really interested in the North Pole and South Pole and there is always huge enthusiasm for lessons on polar bears and penguins. I love the idea of beginning the lesson with a discussion around why the penguins do not fall off the South Pole and the polar bears do not fall off the North Pole. I also love the Earth mosaic. After discussion about the earth’s layers and what lies beneath the sea, this would be a lovely exercise to let the children showcase what they understand of what is above the earth and what lies beneath. The young children that I teach would really enjoy putting their section of the earth together with others to form a full circle and to show the spherical shape of the earth, while still having the opportunity to do their own thing and have their own unique part. As a class I would probably make a papier mache earth as well to further their understanding of the concept.
