The book its self gives a lesson then an experiment made of food. Everything you make is edible. We had most of the ingredients already in the house. You can also download a teachers guide from the website. I found it to be a great bonus to the Eat your Science Homework book. Its got some great tips and bonus lessons the go with the Eat Your Science Homework book. The pictures in the Eat Your Science Homework book are great. I wish I could draw that good. The lessons in the book are wonderful. They had just the right amount of details for the girls age levels and they were fun at the same time. The girls understood exactly what it was telling them the first time. I probably could have done with out all the extra explaining because the lesson did such a good job. The book also has a great glossary in the back. The girls have been learning to use one so this was a great find. The book also includes a safety in the Lab section that has kitchen safety rules. A science review area and an index. The girls have had so much fun with Eat Your Science Homework they want all the other Eat Your Homework books.
