All the activities in this module look worth doing but if I was to start with one it would be the Spherical Earth. I teach 1st and 2nd class and I think that to get any sense of what space is they need to begin with their own planet Earth. The activity in the Spherical Earth is easy for the children to complete without much prior knowledge. I would begin with a video on the earth and what lies beneath us. We would then as a whole class label the parts of the earth. I would encourage the children to be accurate on the layers beneath the earth but then they have the opportunity to be creative with their houses/buildings above the earth. The finished collaborative piece really gives a sense of the shape of the earth. This activity links into so many other areas in the 1st and 2nd class curriculum. Looking forward to doing it with my class in September.
