'Jaffa Moon' in which you model the phases of the Moon using Jaffa cakes? Having discovered how the light part of the Moon changes shape over a lunar month, pupils are asked to reinforce this learning by cutting Jaffa cakes into shapes to simulate the light part of the Moon. By placing these on second dark-side-up Jaffa Cakes, they can see how the dark part of the Moon changes shape at the same time. They then test their understanding by identifying correct versions of predictive sentences which are provided.
This is one of a number of Earthlearningideas about the Moon; all can be found on the website.
