Homeschool science curriculum
Homeschool science curriculum: what to teach at every age, and how to keep it hands-on
Science is the subject homeschool families most often put off, and the one children most often name as their favorite once it actually happens. The gap is almost always logistics: the experiment needs vinegar you do not have, the textbook assumes a lab, the video is twenty minutes of talking before anything moves. A good homeschool science curriculum solves logistics first and content second.
This guide lays out what a child should meet in science from the early years to high school, how many days a week it realistically needs, which programs families actually finish, and the mistakes that turn science into a worksheet subject. It is written for secular and faith-based families alike; where a program takes a position on origins, we say so.
Scope by age
What science looks like at each stage
Use this as a checklist, not a schedule. Children move through it at their own pace, and a strong year can cover two stages.
Early years and K–2
Ages 4–8- Observation before explanation: weather logs, seed jars, magnifying glasses, a nature table that changes each week.
- Living things and their needs, seasons and weather, simple pushes and pulls, floating and sinking, light and shadow.
- Vocabulary through use, not lists. A six-year-old who says 'predict' because you say it during experiments has learned it.
- One question per week the child can answer with their hands. Nothing needs writing down yet beyond a drawing and a label.
Grades 3–5
Ages 8–11- The fair test: changing one thing, keeping the rest the same, recording what happened. This is the core skill of elementary science.
- Life cycles, food chains and habitats, states of matter, simple circuits, forces and simple machines, the solar system, rocks and the water cycle.
- A science notebook with dated entries, labelled diagrams and a sentence or two of conclusion.
- Reading nonfiction: a library book on the topic each week does more than any textbook chapter.
Middle school (6–8)
Ages 11–14- Cells and body systems, genetics basics, chemistry of matter (atoms, elements, reactions), energy and waves, plate tectonics and Earth's history, ecosystems.
- Measurement with real units and real error: mass, volume, temperature, time, and graphing results.
- Longer investigations that run over days, and at least one written lab report per term with method, results and conclusion.
- Reading scientific explanations critically: what evidence supports this claim, and what would change our mind?
High school (9–12)
Ages 14–18- The usual sequence is biology, then chemistry, then physics, with earth or environmental science as a fourth credit. Colleges generally want three lab sciences.
- Each credit is roughly 120–150 hours, of which a quarter should be hands-on lab work you document for the transcript.
- Math readiness matters: chemistry needs confident algebra, physics needs algebra and some trigonometry.
- Dual enrollment at a community college is a strong option for chemistry and physics if you do not want to teach them yourself.
A weekly rhythm that gets done
Homeschool science does not need a school timetable. This is what a sustainable week looks like for most families.
- How often
- 2–3 days a week
- How long
- 30 min (K–2), 45 min (3–5), 60 min (6–12)
One reading day, one experiment or observation day, and an optional notebook or video day. Daily science is not necessary until high school.
Honest comparison
Science programs homeschool families actually finish
Prices are approximate and change; check the publisher. We note worldview because it matters to families on both sides, not to recommend one.
| Program | Approach | Price | Best for |
|---|---|---|---|
| Real Science Odyssey (Pandia Press) Every lesson is built around an activity with household materials. Strong on the fair test. Levels do not need to be done in order. | Secular | About $30–$100 per level | Families who want lab-first secular science in grades 1–8 |
| Apologia Young-earth creationist framing. The high-school courses are well organized for transcripts and widely accepted by Christian colleges. | Faith-based | About $80–$140 per course | Christian families who want a full textbook plus experiments, especially for high school |
| Elemental Science Schedules narration, notebooking and experiments around library books. Origins-neutral in the elementary levels. | Neutral | About $40–$90 per level | Classical or Charlotte Mason families who want a planned week with living books |
| Noeo Science Open-and-go, literature based, ships with a kit so you never hunt for supplies. Pricier for that reason. | Neutral | About $200–$300 per level, kits included | Parents who want everything in the box, including experiment kits |
| Khan Academy, CK-12 and Mystery Science Excellent content, but none of them will get your child's hands wet. Pair with a weekly experiment of your own. | Secular | Free (Mystery Science has a paid tier) | Filling gaps, video explanations and a free spine for budget years |
Avoid these
Mistakes that make science harder than it needs to be
- Buying a textbook for a seven-year-old. Under age nine, science should be almost entirely observation and doing. Reading comes second.
- Skipping the experiment because the supplies are missing. Keep a labelled science box: vinegar, baking soda, balloons, string, magnets, food coloring, a thermometer, a magnifying glass, a kitchen scale.
- Testing recall instead of thinking. Ask what would happen if we changed one thing, not what is the definition of a solid.
- Choosing a program for its worldview and then resenting its pedagogy. Decide how you want science taught first, then filter by worldview.
- Waiting until high school to write anything. A middle schooler who has written eight short lab reports is ready for biology; one who has never written a conclusion is not.
Plan it with Kuraplan
How families use Kuraplan for science
You choose the program and the pace. Kuraplan makes the lessons, worksheets and answer keys that fit around it, for every child in the house.
Experiments that use what is in your kitchen
Ask for a lesson on density, states of matter or plant growth and tell it what you have on hand. You get a step-by-step activity, the science behind it in parent language, and a results page for the child.
One topic, two ages
Teach the solar system to a first grader and a fifth grader from one plan: the same read-aloud and model, then a drawing task for one and a scaled-distance calculation for the other.
Lab reports and notebook pages
Generate a lab report template, a labelled diagram to complete, or a set of comprehension questions on the chapter you just read, ready to print.
One lesson. All your kids.
$49/yr flat, no per-child fees
Write one family lesson, then adjust the reading level, the practice and the response format for each child without rebuilding the day.
Science homeschool FAQ
What is the best homeschool science curriculum?
For secular families in grades 1–8, Real Science Odyssey is the most consistently finished program because every lesson is an activity. Christian families most often choose Apologia, especially for high school. If budget is tight, a library book a week plus one experiment and Khan Academy or CK-12 for explanations covers elementary science well.
How many days a week should we do science?
Two or three. A reading or video day and an experiment day is enough through grade 8. Daily science is only necessary in high school, where each lab-science credit needs around 120–150 hours across the year.
Do I need a science kit?
Not for elementary. A shoebox of household supplies covers most of K–5. Kits become worth it in middle school for circuits and microscopes, and in high school for chemistry, where you also need proper safety equipment.
Which science should a homeschooler take in 9th grade?
Biology is the usual first credit because it needs the least math. Physical science first is fine if algebra is not yet solid. Plan for three lab sciences by graduation if college is likely.
How do I make a homeschool science curriculum for free?
Pick a topic list from your state standards or the Next Generation Science Standards, use library nonfiction as the spine, Khan Academy or CK-12 for explanations, and run one experiment a week from a book like the Usborne Science Activities series. Record what you did in a notebook for your portfolio.
Program details and prices change. Verify with the publisher before buying, and check your state's guide for what is required.
