Ever looked at the moon and wondered if it’s changing shape? Thought the shadow on the moon is due to the Earth being in between the Sun and Moon? Or wondered how come you can see it in the day time? Then this episode is for you!

In this episode, Theo veers away from his favourite topic of maths to answer questions his mum has about her wonderment of the moon. Voted for by the public, this topic delves into the eight phases of the moon, what happens to water as the moon orbits Earth and if we can see the moon during the daytime.

We’re not experts, just curious Casements enjoying a fun debate, but here’s a link to a video that might help with some visuals to support our conversation…
