Aoife,
it’s interesting that you have given the children everyday object to make their shadows ( compared to Luke who has used balls) – that will make a big difference to how the shadows appear.
I like that you have used a prompt ( Show examples of shadows in different settings (e.g., outdoors under the sun, indoors with a lamp).) and have explicitly elicited the children’s understanding by asking
the children what they already know about shadows and how they think shadows are formed.
If they then explain what they expect to happen (their prediction) as a result of their understanding then they are fully carrying out inquiry learning in science.
