Whizz Pop Bang is a paper magazine (yeah, I know – old school, right? 🙂 ). It’s great for younger kids, probably 7-11 age range (but that will depend on your child). It has different themes each issue, and includes suggestions for experiments and things to do. My son, who really isn’t keen on reading anything written on real paper, loves it.
