Ask your pupils to make a log of the shape of the moon over a lunar month, noting the date and time of each observation. They could either do this by direct observation or by research on the internet. When their logs have been completed, ask them to model the phases of the moon using Jaffa CakesTM. They will have to cut or nibble the biscuits carefully to make some of the phases. Then ask them to use their model to complete a series of predictions.
Needless to say, this activity will be much enjoyed by your pupils! It is the first of a series of ELIs about the Moon.
