Science is an important subject at school. It can also a good career choice for students who get "bitten" by the "science bug". But many of the science kits made are targeted towards boys. Unless a girl is really interested in science these boy-targeted kits might not create any enthusiasm.
There are some science kits that are more interesting for girls who have either been bitten by the "science bug" or are still needing to develop enthusiasm for this school topic.
