Science

A senior capstone across molecular biology, geology, physics, chemistry, anatomy, astronomy, and creation apologetics, in 180 lessons.

About this course

Twelfth grade is a capstone rather than a new specialization. The first half of the year covers each field once at senior level: DNA replication and gene regulation, chromosomal inheritance, CRISPR and genetic engineering, population ecology and conservation biology; plate tectonics, geologic dating methods, ocean circulation, and atmospheric science; kinematics through nuclear physics; the solar system, stellar life cycles, galaxies, cosmology, and the search for extraterrestrial life; all eleven body systems including reproduction and development; and chemistry from electron configuration and VSEPR through stoichiometry, equilibrium, thermochemistry, organic chemistry, and electrochemistry. A stewardship unit covers habitat loss, water and soil, energy trade-offs, waste and Christian simplicity, conservation practice, and environmental justice.

The second half is the more interesting one. Rather than repeating the first half, it takes the same fields into applied and case-driven territory: pedigree analysis and probability, meiosis with crossing over and genetic mapping, gene therapy and cloning, speciation and where the boundaries of created kinds lie, human demography, fault hazard and the engineering response to it, volcano monitoring and historic eruptions, a post-Flood single ice age model, standing waves and the Doppler effect, magnetism from the compass to the MRI machine, entropy and the arrow of time, the four quantum numbers, limiting reactants and empirical formulas, and the placenta, labor, and the newborn's first breath with the circulatory rerouting it requires.

There are 180 lessons in 15 units of 12, each planned for about 50 minutes. Lessons are self-contained readings with defined terms, worked examples, and historical context, and they end with a Reflect question and an Investigate prompt that sends your student to look something up; neither is auto-graded, so those are yours to review. The graded item is the ten-question multiple-choice quiz at the end of each lesson. Listed materials are pencil, paper, and crayons, with no lab kit or supervised lab component, so documented lab hours for a transcript would need to be arranged separately by you and your family.

This is the year the curriculum argues its position most directly and expects a senior to weigh arguments. Evolution is not skipped; one lesson lays out descent with modification, natural selection, and the evidence mainstream biologists cite, then presents the objections raised by intelligent design and creation science and asks your student to distinguish observed natural selection from inferred common descent. A geology lesson draws the line between operational and historical science, works through unconformities and discordant radiometric dates, and presents the RATE project's helium-in-zircon argument for accelerated decay. Astronomy weighs the evidence that the universe had a beginning and the competing readings of it. The consistent position is creation and a young earth, presented with the counterarguments named rather than left out.

What this lesson is for

  • Students will explore and observe Environmental Stewardship - Lesson 7
  • Students will describe what they learned about God's creation

For by him were all things created, that are in heaven, and that are in earth, visible and invisible.

Colossians 1:16

Energy: Sources, Trade-offs, and Stewardship

Every human activity requires energy. The choices a society makes about how to obtain that energy have profound and lasting consequences for creation, communities, and future generations.

Fossil Fuels — Formation and Reality: Coal, oil, and natural gas are the remains of ancient organic material compressed over long periods. They represent concentrated stored energy. Extraction methods include surface mining (coal), conventional drilling (oil and gas), and hydraulic fracturing (fracking).

Real Costs of Fossil Fuels:

  • Air and water contamination from extraction, processing, and combustion
  • CO2 emissions alter the composition of the atmosphere
  • Finite supply — not replenished on any human timescale
  • Geopolitical instability and price volatility tied to concentrated reserves

Renewable Energy Options and Their Trade-offs:

  • Solar photovoltaic: Cost has fallen over 90% since 2010; requires large land area and manufacturing inputs; intermittent
  • Wind: Effective in open regions and offshore; intermittent; affects bird and bat populations; visual and noise impacts
  • Hydroelectric: Reliable baseload power; but dams fragment rivers, alter sediment flow, and displace communities
  • Geothermal: Reliable and low-emission; geographically restricted to volcanic regions
  • Biomass: Renewable if managed sustainably; still produces combustion emissions

The Stewardship Calculation: No energy source is free of consequences. Faithful stewardship demands honest, full-cycle accounting of all costs: environmental, economic, social, and long-term. Christians should resist both reflexive rejection of all fossil fuels and uncritical promotion of them without regard to real costs.

"Moreover it is required in stewards, that a man be found faithful." — 1 Corinthians 4:2

Reflect: What criteria should guide a Christian household or community in evaluating energy choices? Is there a single "most ethical" energy option, or does the answer depend on context?

Practice: Research the full lifecycle of one renewable energy technology. List three genuine environmental benefits and three genuine environmental costs or trade-offs.

Homework

Write a short paragraph about Environmental stewardship - lesson 7.

Note for the parent

Today's lesson covers Environmental Stewardship - Lesson 7. Estimated time: 50 minutes. Encourage independent work but be available for questions.

The first three of this lesson's 10 questions

What are the three major categories of fossil fuels discussed in this lesson?

  1. Uranium, natural gas, and geothermal heat
  2. Shale, peat, and lignite
  3. Biomass, wind, and solar
  4. Coal, oil, and natural gas
Show the answer

Answer: Coal, oil, and natural gas

What are 'real costs' of fossil fuel use identified in this lesson?

  1. Only the financial cost of purchasing fuel
  2. Noise pollution from extraction equipment
  3. The inconvenience of transporting fuel to remote areas
  4. Air and water contamination, CO2 emissions, finite supply, and geopolitical instability
Show the answer

Answer: Air and water contamination, CO2 emissions, finite supply, and geopolitical instability

Solar photovoltaic energy costs have fallen by approximately what percentage since 2010?

  1. 25%
  2. 50%
  3. 90%
  4. 10%
Show the answer

Answer: 90%

Another 7 questions follow in the lesson itself, each one graded the moment it is answered.
