• The modules were switched around to allow for an "Atoms First" teaching approach.
• There are updated illustrations.
• Any out-of-date science information was removed.
• There are added “call-out” boxes so that students can recognize God’s fingerprint throughout creation.
• Information in Module 2, which was difficult for many students, was moved to Module 12.
• Information on density was moved to Module 6 (previously in Module 1).
• Information on temperature was moved to Module 1 (previously in Module 2)
• Information on matter was moved to Module 2 (previously in Module 4).
