A book of experience to do with kids. Separated in categories, so easy to find what you're looking for. There is also a bit of information and facts about the subject of the experience. Could be use for teaching science in elementary school, or simply to do with your own child to have fun and learn at the same time. So why only 3 stars? The experience are unfortunately a little bit too basic for my liking, some could easily came to you just by thinking a bit. Not bad, but simple.
