Snug as a bug is making a bug hotel out of wood, canes etc. This will cover no. 4 of the creative challenge: design and make something eg birdhouse, model etc (so a bug hotel instead of a birdhouse).
(edited by JS to add badge link)
ask parents to send in outer casing (plastic drinks bottle, tin can etc), cardboard loo rolls (to roll up into bug hotel)
Gather leaves, stems, cones etc
