Ornaith,
the inquiry framework you have used is close to the 5E and shares some features with the Framework for Inquiry that is used by Science Foundation Ireland’s Curious Minds programme.
You have a prompt -picture or videos of day vs night.
I’d suggest that instead of “make observations about the sky,” that you make observations of the sky. The Moon can be seen in the daytime sky (see the material in Module 2) at some times of the month, this can be a direct experience that the children will remember.
It is less clear how working with torches and cutouts of the Moon and stars will help children to understand that the Moon and stars are luminous objects, since they will be lighting them up by shining a light on them, rather than observing them as lit objects of their own.
You might want to look as this ESERO activity Light and Darkness, to investigate “what objects look like when there is no light and look at
objects that give off light.”
