Hi Sinead,
I think this is an excellent Space Week Plan.
In English I love the idea of taking something familiar like a passport and applying it to going to space and then the idea of the children deciding what they need to bring sounds like great fun. To extend this further could you have them pack a suitcase with things they may need to bring and then discuss further. Maybe you could even put in some things and have the children discuss if you will need it/ how you will use it. E.g. starting the discussion of how people brush their teeth in space. Chris Hadfield has a lovely video about this.
I absolutely love the idea of using shape poems in rocket shapes and I can only imagine the level of engagement you would get with this idea.
In the past I’ve done the papier mache planets and they are so so much fun and really get the children thinking about the appearance of each planet and how they differ. I personally found this the most effective way to get the children to remember the various attributes of the planets.
