As part of the Space themed Homeschool this week we used egg shells (cleaned) and the boys smashed them with a hammer. Then glued them to a piece of paper to make a moon. The best size of the pieces was probably the size of a 5p.
The next day they used rock painting pens to add colour to the shells to change them to the sun and Earth .
My 9 year old said he enjoyed smashing the egg shells and that he could change it from a moon to the Earth .
