I would use the idea of building our own space rockets as the theme for lessons during space week.
I would start with a poem e.g. Kenn Nesbitt has some good ones or reading a story such as aliens lobe underpants to engage the childre.
Then explore the idea of space and what it means to the children.
What do they know about it already. What we look up at the sky What can we see?
Introduce the ideas of telescopes etc and why these can help us see more.
This would lead onto a discussion to see if we wanted to actually see dance better how would we do it?
Children would then look at pictures , video clips of the moon landing and the more recent Mars trip to understand the role of rockets and astronauts.
They can sketch ideas for what they think they would need in their rocket ship. Then using ‘junk art’ material the children can work individually or I’m groups to create their own rockets
How would they take off? Having seeing the use of bicarbonate of soda and vinegar in volcano experiments previously. I would let them expwriment outside with trying to make their rocket move.
