Some of these ideas were on the Cornerstones letter that went out at the beginning of our Moon Zoom project, so you may have done them already. I'll add a few others as well.
There are lots of ideas on websites and shared on Facebook and Pinterest, for crafting, Science, Maths, English, etc. BBC Bitesize & BBC iplayer are great too.
Astronaut's kit - Linked to the English text "What Ever Next!", you could have a go at making a space rocket from things about the house, or maybe a helmet from a box or paper bag (please remind children how dangerous putting a plastic bag on their heads is).
You could wear an adult T-shirt, with a knot at the bottom and stuff it with extra clothes, cushions etc to make a space suite.
To make the space walk jet pack you need a cereal packet and 1 or 2 pop bottles, plus decorations. For best results turn the box inside out before you paint. If you have limited supplies of paint, then just leave it blank, or add a bit of colour with crayons, or felts.
Solar System Mobile - you can make a mobile in a variety of ways - on 1 string, attached to a coat hanger, maybe an embroidery hoop, or a crossed pair of gardening sticks. You can make the planets by making balls from sweet papers & foil, paper mache, 2 circles of card slotted together, or pictures cut out. Can you put them in order? Do you remember the mnemonic you made a school to remember? Maybe you could make a new one?
