Systems, Energy Flow, and Biogeochemical Cycles: Science Unit 1, Grade 12 (Letters & Devotion)

Description

Systems, Energy Flow, and Biogeochemical Cycles is Unit 1 of Environmental Science: Systems, Evidence, and Choices (Part 1) (Grade 12), the Letters & Devotion Science course, complete in one printable PDF: 8 lessons, the unit check-up and the answer key, 73 pages.

• The 10% trophic energy-transfer rule
• The mechanism of energy loss between trophic levels
• The distinction between biomass pyramids and energy pyramids
• Biomass estimation from field-plot sampling data
• The carbon or nitrogen biogeochemical cycle and its rate-limiting processes
• The relationship between GPP, NPP, and respiration
• Transfer of trophic energy-transfer and biogeochemical cycling constraints to an unfamiliar engineered or natural system
• The internal consistency of a food-web capacity claim against energy-transfer constraints

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.
