Science

High school general science: stoichiometry, gas laws, kinematics, Ohm's law, genetics, geology, and cosmology, in 180 lessons.

About this course

Ninth grade is a broad high school science year that touches biology, chemistry, physics, earth science, astronomy, human physiology, and environmental science rather than specializing in one. Life science covers membrane transport, the cell cycle, DNA and protein synthesis, Mendel's laws, variation within created kinds, classification, and biogeochemical cycles. Chemistry is the heaviest strand: the Bohr model, electron configuration, ionic and covalent bonding, formulas and naming, balancing equations, stoichiometry with moles and Avogadro's number, the gas laws, reaction energy, solutions, organic chemistry, catalysts and enzymes, and nuclear chemistry. Physics covers kinematics, Newton's three laws, work, energy and power, waves, the electromagnetic spectrum, circuits and Ohm's law, magnetism, thermodynamics, mechanical advantage, and optics. Earth science runs plate tectonics, minerals, weathering, soil, and groundwater, with full lessons on Flood geology and young-earth creation science. Astronomy covers the scale of the universe, the sun, planets, the H-R diagram, galaxies, and cosmology. Human body work is at physiology level: homeostasis, immunity, the endocrine and nervous systems, pharmacology, and one lesson on mental health that discusses depression, anxiety, and schizophrenia in terms of both brain chemistry and spiritual care.

There are 180 lessons in 15 units of 12, each planned for about 50 minutes, which is a full daily-lesson school year. The last seven units cover the same ground as the first seven, but the lessons are separately written in a condensed running-prose style rather than reprinted, so the second half of the year functions as a rewritten review pass. A lesson opens with a wonder question, teaches through headed sections with worked example problems and defined vocabulary, includes an observe-or-experiment and a record-and-share step, and ends with a ten-question multiple-choice quiz that grades itself. Homework is a written paragraph.

Listed materials are pencil, paper, and crayons. There is no lab kit and no supervised lab component, so if your student needs documented lab hours for a transcript or an outside requirement, you and your family will need to arrange that separately. What the course does demand is arithmetic: mole conversions, molar mass, gas law rearrangements, and Ohm's law all require confident work with decimals, ratios, and scientific notation, so a student taking Algebra I concurrently or already finished with it will be on surer footing. The creation position is stated and argued rather than assumed. The cosmology lesson presents the Big Bang model with its standard evidence (redshift, the cosmic microwave background, light element abundances), then presents young-earth alternatives such as Humphreys's white hole cosmology and Hartnett's model, and treats both as active work.

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

Biblical Stewardship of Creation

The Christian doctrine of creation stewardship is rooted in the very beginning of Scripture. Genesis 1:28 records God's command to humanity: "Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth." Genesis 2:15 describes the specific task: "And the LORD God took the man, and put him into the garden of Eden to dress it and to keep it."

These foundational texts establish several critical truths about humanity's relationship to the natural world. First, the EARTH BELONGS TO GOD, NOT TO HUMANITY: "The earth is the LORD's, and the fulness thereof; the world, and they that dwell therein" (Psalm 24:1). Humans are stewards — managers entrusted with the care of something that belongs to another — not absolute owners who may do with creation whatever they please. Second, the DOMINION MANDATE is a responsibility, not a license. The Hebrew words for "dress" (abad) and "keep" (shamar) in Genesis 2:15 carry meanings of service, labor, guarding, and preserving — active, caring oversight, not careless exploitation. Third, creation has INTRINSIC VALUE because God created it and declared it "very good" (Genesis 1:31) — it has value apart from its usefulness to humans.

Throughout Scripture, God expresses care for the natural world and its creatures. Psalm 104 is an extended meditation on God's provision for every creature. Proverbs 12:10 states: "A righteous man regards the life of his animal." The Mosaic law included provisions for land rest (the Sabbatical Year — Leviticus 25:1-7), care for working animals (Deuteronomy 25:4), and protection of mother birds (Deuteronomy 22:6-7) — principles that reflect a God who cares for the welfare of His creation.

The Fall (Genesis 3) introduced death, decay, thorns, and the subjection of creation to frustration (Romans 8:20-22). Environmental degradation, disease, and natural disasters entered the world through sin. The creation now "groaneth and travaileth in pain together until now" (Romans 8:22), awaiting the final restoration when God makes "all things new" (Revelation 21:5). In the meantime, Christian stewardship means working against the effects of the Fall where we can — reducing pollution, conserving biodiversity, farming sustainably, and using natural resources wisely — as an expression of love for God and love for neighbor (including future generations who will inherit what we leave behind).

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

The biblical mandate for creation stewardship begins in Genesis 2:15, which states that God placed humans in the garden 'to work it and take care of it.' This establishes that humans have a responsibility to:

  1. Work and care for the created world as faithful stewards under God
  2. Exploit creation for maximum human benefit
  3. Leave nature completely untouched by human activity
  4. Prioritize animal welfare above human wellbeing in all cases
Show the answer

Answer: Work and care for the created world as faithful stewards under God

The doctrine of dominion (Genesis 1:28) gives humans authority over creation. Biblical stewardship teaches that this dominion must be exercised:

  1. As absolute ownership with no accountability
  2. Only over domesticated animals, not wild species or land
  3. Only by government authorities, not individual Christians
  4. As responsible management under God, to whom we are accountable for how we treat creation
Show the answer

Answer: As responsible management under God, to whom we are accountable for how we treat creation

Psalm 24:1 declares 'The earth is the Lord's, and everything in it.' How does this verse shape a Christian's view of environmental stewardship?

  1. If the earth belongs to God, humans should not use it at all
  2. Because the earth is God's property, we are tenants and managers responsible to Him for how we treat it
  3. The earth being God's means He will always restore whatever damage humans cause
  4. This verse only applies to ancient Israel, not modern Christians
Show the answer

Answer: Because the earth is God's property, we are tenants and managers responsible to Him for how we treat it
