the experimental laboratory is really great. so that makes it really fun to experiment. and well that's an all-round box is on Biology Physics and Chemistry. if a an issue particularly like you can later buy a box only to physics, chemistry or biology. so it makes learning fun. However, you can not make the experiments as often. the chemicals are irgentwann depleted once. you need for many experiments extra things that are but to find in a normal household. (Eg water or foil)
