Write suggestions to be put in a box and then discuss each of them and how the ideas can be used to improve meetings. You could also use a noticeboard or similar and stick the suggestions up with blue-tac or using post-it notes.
Allow the young people to come up with any suggestions they like. You will get a certain amount of silly suggestions (like the cub who sugegsted a trip to Mars) but you'll also get some absolute gems that will be the star of your programme.
