Lollipop moon; modelling the phases of the Moon

Today's new ELI is 'Lollipop moon'. In this activity the phases of the Moon are modelled with a ball, lollipops and a bright light, as viewed from 'outside' the model. This follows 'Polystyrene moon' which visualised the phases on the Moon as viewed from 'inside' the model. The first in this series was 'Jaffa moon' which developed observational, recording and modelling skills. These activities show the progressive teaching of this topic.
All Earth in Space earthlearningideas can be seen on the website and, like all these wonderful activities, they are free to download.
