This is a complete curriculum about food chemistry for ages 10 to 16. The first half of the book (130 pages) is the student text which gives all the information needed. The text is lively and includes some cartoons and whimsical humor while still providing a high level of content that is suitable even for high school students. The text is organized around the theme of dissecting a meal down to its molecular components. We learn about all the standard topics of food chemistry as we look in depth at each food: water, salt, sugar, milk, butter, cheese, bread, meat, beans, potatoes, plant-based meat, eggs, gelatins, meringue, chocolate, sweeteners. There is also a short history of the discovery of vitamins, plus explanations of saturated and unsaturated fats, trans and cis fats, omega-3s, triglycerides, saccharides, enzymes, and more. The second half of the book is the teacher's section which provides suggestions for labs, experiments, cooking activities, crafts, and games.

This is the student text portion of the curriculum "The Elements; Ingredients of the Universe," by the same author. The student text is provided as a convenience to teachers and parents who have multiple students and would like each student to have their own booklet. ( The full curriculum book includes a copy of the student text.)

Carbon Chemistry is an introduction to organic chemistry for ages 10-15. It is intended as a follow-up to "The Elements" by the same author, but can be used independently if the student has some basic knowledge about atoms, molecules, and the Periodic Table. The first section is a student booklet of nine chapters, covering topics such as the structure of a carbon atom, hydrocarbons, alkanes, alkenes, alkynes, functional groups, soaps, plastics, rubber, nylon, carbon dioxide and monoxide, calcium carbonate and limestone, the carbon cycle, radioactive carbon (carbon-14), and quarks. Despite the "heavy" nature of the topics, the text is light, easy-to-read and even humorous in many places. There are review questions at the end of each chapter, plus some review word puzzles. The second half of the book is a teacher''s guide that provides additional activities including games, songs, recipes, lab experiments, skits, crafts, and even a dance.
