Miss J had been working on a middle school level chemistry course using several books I located for her. After completing that, I found a series of 4 books from Usborne that I purchased for her to go through. She has really been enjoying them. She is currently on the 3rd one and will finish the 4th by the end of May pretty easily.
The series is Kitchen Science: The Complete Collection published by Kane Miller. It is a set of four books: The Math of a Milkshake, The Chemistry of Cola, The Biology of a Banana, and The Physics of Popcorn. Each of the books, as is indicated by the titles, handles a branch of science or math. The books have been a lot of fun, with tons of unique tidbits of information that were interesting. They have presented a lot of ideas, some in depth, some fairly simply. They have been a great exploration of each of the branches of education they address. They all have lots of experiments, some of which we had already done and some we had not. The books had a good balance of reading, quizzing, and doing.
I found these books to be fantastic for middle school, as they push the envelope of known information in a way that has generally resulted in Miss J wanting to find out more about it. We have pulled additional books to complement the learning because she wanted more. Rabbit trails that produced more in depth learning.
The depth of information definitely requires a parent to be around to help with some of it but they are manageable for student led learning. If you have a middle school student and are looking for an overview course that will help students really learn about the different parts of science and math, these are great. There is plenty of material for a year-long course in my opinion, especially if you are doing all of the experiments, quizzes, and tests. This is a recommend from me.
I was not asked to write this and I purchased these materials myself. I am not a Usborne consultant but will happily connect you with Leslie (who I purchased these through) if you would like to order these or something else.
