Moonscape- bag of split peas & a bag of beans, sprayed silver. Moon buggy - dumper truck covered in tin foil. Astronauts - printed out photos stuck on toilet rolls. Rocket - plastic cup with craft foam top & wings, duct tape windows.
LOVE the idea of creating little play trays lined with grass or moss for dramatic play scenarios. Combine with logs, little felt people, animals, etc.of course these clearly aren't for children, but the idea is adaptable.
