Our favourite smoothie supremos, Innocent, have teamed up with The Tree Council for Walk in the Woods month (May), and put together an innocent tree trail for kids.

You can download a fun worksheet at www.innocentkids.co.uk/trees. Then head to your nearest Walk in the Woods events (there's one at Kew Gardens and lots more) or go to your local park with friends. They'll be collecting bark rubbings, hugging oaks, drawing bugs and flowers and spotting leaves (and the odd squirrel). Then upload a picture with your completed trail onto the innocent website and you might even win a prize!
