• Quadrat sampling and point-count field survey procedures
• Attribution of a specific biodiversity change to one of several competing stressors
• Comparison of local survey data against regional historical baseline data
• Applying trophic cascade and threshold concepts to evaluate an untaught conservation intervention
• Background extinction rate as a comparison baseline for current extinction rates

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
