I found this idea online a while ago and I was itching to try it! You take a small piece of card and draw a simple landscape (or whatever you want) on it. You then take play dough (the school I work at is in the fortunate position to have some store bought play dough though you can make as well) and using earbuds and your fingers you smear the dough over your page. You can then take sticks and scratch into it. It’s far from a perfect media but very fun and we all loved it!
