This kit has really clear directions, and many experiments. It does require quite a bit of reading, and I would definitely have an adult present during the experiments. The only complaint I would add is that the experiments do require quite a few outside materials, which isn't mentioned in the sales literature. It asks for things like sand, coffee filters, clean glass jars with lids(old jam jars work), rubbing alcohol, this does add to the overall cost of the kit, and means that the kit fills a good size box, not the modest box shown.
