Query: Great Curriculum Supplement

I purchased this to supplement my homeschool high school and middle school curriculum. This is an excellent product, both for studying nutrition and for studying biology. Their explanation of the molecules of life, followed by tons of great and detailed information, presented in an easy to assimilate format, makes this an extremely valuable asset. If you, or your student, desire to understand proteins, carbohydrates, lipids, and nucleic acids, this is the tool to buy! I've taught science in nearly every type of school setting for over 20 years and wish I'd found this sooner. I find the Standard Deviants videos very useful and appreciate them all, but this one stands out as a best buy.
