Weaving: Get some large twigs from the garden, preferably with a few smaller twigs attached. Weave in, out and around with a variety of different lengths, colours and thicknesses of wool, string, ribbon, lace, fabric and paper.
Windchimes: On a long piece of string, thread metal milk bottle tops (washed), penne pasta to separate, balls of silver foil, crinkly cellophane and anything else that might make noise. Hang up outside.
If they don't need to take it home, then water painting is great if you have an outdoor space or wall. Simply get pots of water and a range of different size paintbrushes. Let the children "paint" the floor or wall. It's great for encouraging big movements!
Musical instruments: 2 x yoghurt pots filled with a choice of sand, dried lentils, dried peas etc. stick together with parcel tape. Wrap in crepe paper. An alternative to yoghurt pots is clean tin cans, with a piece of paper over the top, held on with sticky tape or an elastic band.
A bit messy: Symmetry pictures - fold pieces of paper in half. Get the children to paint blobs on one side. Then, fold the paper in half again and press down. Open up and you have a symmetrical picture.
Fish: Cut out a fish shape for each child and lots of different colour cirles. Children stick the circles all over the fish to make scales.
