Science at Home: Experiments, Kits and Curriculum for Elementary

Your child has been asking why the sky is blue, why ice floats, and what would happen if you put a grape in the microwave. (Do not put a grape in the microwave.) The good news is that you are already doing science. The question is whether to formalize it, how much to spend, and how to keep the experiments from taking over the kitchen on a Tuesday.

Elementary science at home does not need to look like a classroom lab. It needs a plan that fits your week, materials you can actually find, and a parent who is willing to say “I don’t know, let’s find out” without panic. Here is how the main approaches compare, what they cost, and which ones survive the kitchen-table test.

The short answer

Pick one approach. Try it for a month. If it is working, keep going. If it is not, switch. The four main options for elementary homeschool science are textbook programs, literature-based curricula, unit studies and experiment kits. Each fits a different family. None of them is the one right answer.

The main approaches

Textbook programs

These are the closest to what a school uses: a student book, a teacher guide, sometimes a workbook, and experiments built into the lessons. They cover topics in a set order over the school year. Examples include Apologia (religious, creation-based), Real Science Odyssey (secular) and Building Foundations of Scientific Understanding (secular, Socratic).

Textbook programs give you structure. You open the book, teach the lesson, do the experiment. The tradeoff is that the experiments sometimes require materials you do not have, the lessons can be dry for younger kids, and the parent prep time varies from five minutes to an hour depending on the program.

Literature-based curricula

These build science around real books rather than textbooks. You read a living book about insects, then go outside and look at insects, then maybe draw one. Bookshark (secular) and Sonlight (religious) both include science in their packages. Some families piece together their own using library books and a topic list.

The strength is engagement. A well-written book about volcanoes is more interesting to most seven-year-olds than a textbook chapter about volcanoes. The weakness is that coverage can be uneven. You might spend three weeks on animals and skip physics entirely unless you plan the topics yourself.

Unit studies

A unit study takes one topic and covers it across subjects: read about the ocean (language arts), measure saltwater density (science and math), find the Pacific on a map (geography), draw a coral reef (art). Konos, Five in a Row and the Build Your Library science units are examples.

Unit studies are good for families with multiple ages, because everyone studies the same topic at different depths. They are labor-intensive for the parent. Someone has to plan or buy the unit, gather the materials and run the project. If you enjoy that, unit studies are a good fit. If you are already short on prep time, they may not survive the first month.

Experiment kits and subscription boxes

These arrive with materials and instructions. You open the box, follow the steps, and something happens. Kiwi Crate (now KiwiCo), MEL Science, and various one-off kits on bookstore shelves fall into this category.

Kits solve the materials problem. You do not need to buy pipettes, vinegar and baking soda separately. They are also expensive per experiment, and the science content is sometimes thin: a fun activity without much explanation of why it worked. Kits are useful as supplements, not usually as a full science program.

The kitchen-table test

Here is where most science plans meet reality. Ask yourself:

How much prep time do I actually have? If the answer is “ten minutes the night before,” a textbook program or a kit will survive the week. A unit study probably will not.

How independent is my child? A third grader who reads well can do some textbook lessons with minimal help. A kindergartner needs you for everything. Match the program to the child, not the catalog description.

What happens with siblings? If you have a five-year-old and an eight-year-old, a unit study lets them work on the same topic. A grade-specific textbook means two separate lessons or one child waiting. Kits can sometimes be shared. Literature works for read-alouds at any age.

What if it does not work? Elementary science curricula are relatively cheap compared to math programs. If the first pick is wrong, sell it in a homeschool group and try something else. The science will not be ruined by a month of experiments from the library instead.

Can I find the materials? Some programs list supplies you can get at a grocery store. Others list lab-grade chemicals you cannot. Before you buy, flip to the materials list for the first ten lessons. If you need to order from a specialty supplier for lesson three, that is worth knowing now.

A real week

This schedule is fictional and illustrative. The Navarro family is not real.

The Navarros homeschool two kids, ages 6 and 9. They use a literature-based approach for science, with library books and simple experiments.

Day	Science (about 30 minutes)	Notes
Monday	Read chapter from a book about weather. Discuss. 9-year-old writes three sentences about what they learned.	6-year-old draws a picture of clouds instead of writing.
Tuesday	No science. Extra math day.	Dentist appointment in the afternoon.
Wednesday	Experiment: make a rain gauge from a plastic bottle. Measure for the rest of the week.	Both kids do this together. Takes 20 minutes plus cleanup.
Thursday	Read next chapter. 9-year-old answers discussion questions. 6-year-old does a coloring page about the water cycle.	Parent reads aloud for both.
Friday	Check rain gauge. Record measurement. Watch a 15-minute video about storms.	Short day. Co-op in the afternoon.

This example is fictional and illustrative. The Navarro family is not real.

That is two reading days, one experiment, one follow-up measurement and one video. It covers weather for the week in about two and a half hours total. It is not flashy. It works.

What to try first

If you have never taught science at home, here is a low-risk starting plan:

1. Go to the library. Pick three or four nonfiction science books at your child’s reading level on a topic they are interested in. Insects, space, weather, the human body, magnets. It does not matter which.
2. Read one book together. Spend 15 to 20 minutes, twice a week.
3. Do one simple experiment per week. The Smithsonian Science Education Center has free resources and lesson plans [3]. YouTube has thousands of safe elementary experiments with grocery-store materials.
4. Keep a science notebook. Your child draws what they observed, writes a sentence or two, and dates the page. This also counts toward writing practice.
5. After a month, decide. If the library approach is working, keep it. If you want more structure, now you know what you are looking for in a curriculum, because you have seen what your child responds to.

The NGSS framework can help you check that you are covering the main topics over the year: life science, physical science, earth and space science, and engineering practices [2]. You do not need to follow it rigidly, but it is a useful map.

Common mistakes

Trying to cover everything in the first month. Elementary science is wide, not deep. You have years. It is fine to spend October on insects and November on magnets and skip rocks until spring.

Buying a curriculum before you know your child’s style. The library month tells you whether your kid wants to read, watch, build or all three. Buy after you know.

Skipping science because reading and math feel more urgent. Reading and math are the daily priorities, yes. But science twice a week keeps curiosity alive, and it practices reading, writing and measurement at the same time. It is not a luxury subject.

Making every experiment a production. The baking soda volcano is fun once. Routine science is smaller: measuring, observing, recording, predicting. The spectacular experiments are dessert, not dinner.

Forgetting to check what your state requires. Most states list science as a required subject for homeschoolers [5]. That usually means you need to teach it, not that you need a specific curriculum. But check, because a few states want more detail than others.

Check your state’s rules. Homeschool law varies by state and can change: notice requirements, required subjects, attendance, assessments and record-keeping all differ. Check your state department of education’s current guidance before you start or change anything. If you think your child may have a learning disability, you can ask your local school district about an evaluation; districts have duties to identify children with disabilities, including many who are homeschooled, though what’s offered varies by state.
