A really good homeschool science kit will have a lot of activites for the child to do. Science is a subject that is best learned by doing the activities rather than reading about them in a textbook. Some of the "activities" can involve doing extensive research and then conducting an experiment. Other activities may involve following a set of instructions to do a certain hands-on project. Conducting research and experimentation are some of the best "activities" to do while using a homeschool science kit to teach a child.
