The 3rd Edition of Biology was significantly revised and updated. Some of the updates include:

• Updated content to present the most current science
• A reorganized structure of the information, which helps students logically progress through their biological studies
• Experiments which have been updated or replaced, and the addition of new experiments
• New illustrations and infographics that help students break down and visually digest difficult concepts, in addition to updated images and illustrations
• New content, including a new section on photosynthesis and a new section on diseases.
• An overhaul of the section on genetics, including more information on DNA
• Updated information on the Biological Classification System

We have also transitioned to softcover for our 7th-12th grade science textbooks.

The components of the new 3rd edition course are not compatible with the 2nd edition.
