When you select your materials, think about the properties they need. The main sail needs to be light, so would it be good to use metal, wood or a thin plastic bag? (Alternatively you could use a newspaper or some fabric, depending on what you have at home). The sticks making the cross shape need to be light and hold their shape. Maybe you could find some suitable thin twigs on your walk. When you have finished attaching the string, ribbons etc, enjoy testing it out.
Afterwards, have a conversation - did it fly well? Would you do anything differently, if you were to make it again? Would you use the same materials?
