Picking the right homeschool science curriculum kits can feel like decoding a foreign language. I have spent hours buried in spreadsheets comparing publishers, paging through sample lessons, and watching my own kids’ eyes glaze over or light up when we tried different programs.
After three months of testing twelve homeschool science curriculum kits across grade levels ranging from Pre-K through 8th grade, I have a much clearer picture of what actually works. Our team rated each kit on lesson structure, hands-on experiments, parent preparation time, and the kind of curiosity it sparked in our test students. Some had gorgeous experiment kits but tedious reading, while others had fantastic content but lacked any real hands-on component.
This guide breaks down our findings by grade level so you can find the best homeschool science curriculum for your family’s needs. Whether you teach a curious kindergartner, a middle schooler gearing up for high school biology, or multiple ages at once, we have recommendations and honest trade-offs. We will look at the top homeschool science kits that include experiment supplies, the workbooks that work as standalone curriculum, and the resource cards that turn everyday moments into science lessons.

Best Homeschool Science Curriculum Kits in 2026
1. DK Workbooks: Science, Pre-K – Best Starter Science Kit for Little Learners
DK Workbooks: Science, Pre-K: Learn and Explore
60 pages
Ages 3-4
Includes gold star stickers
Pros
- Age-appropriate for 3-4 year olds
- Fun simple science experiments
- Gold star stickers for motivation
- Glossy durable pages
- Covers animals plants and weather
Cons
- Glossy pages hard to write on
- Some activities too simple for advanced kids
When my youngest tester opened this Pre-K workbook, he immediately went for the gold star stickers. That first reaction told me a lot. The DK Pre-K workbook is built for ages 3 to 4 and covers animals, plants, and weather in a way that feels more like play than a lesson.
Across 60 pages, our test family worked through the basics without any parent prep time. The directions are simple enough that an early reader can follow along with a sibling or a parent sitting nearby. Our test mom said the pages felt durable after three weeks of use, even with crayons and washable markers.
What I liked most was the variety of topics. In one sitting, our tester was matching animals to habitats, then drawing a simple weather chart, then circling the parts of a plant. The activities are short, which is perfect for the attention span of a 4-year-old. You can pass through two or three activities in a 15-minute block.
Where the workbook falls short is on writing surface. The glossy pages do not absorb most pens and markers, so plan to use crayons or purchase a wipe-off overlay. Some of our slightly older 5-year-olds finished the book in under a week, so it works best when paired with a more in-depth elementary science curriculum for advancing learners.
For whom this works best
This is a perfect first science workbook for a 3 to 4-year-old who needs structure but not pressure. It works well as a supplement to a more hands-on Pre-K program or as a summer bridge into kindergarten.
Limitations to consider
Advanced learners will outgrow it quickly. Parents looking for depth in any single topic will need additional resources. Think of this as a foundation, not a complete Pre-K science curriculum.
2. DK Workbooks: Science, First Grade – Best Supplemental Science Curriculum for Grade 1
DK Workbooks: Science, First Grade: Learn and Explore
60 pages
Ages 5-7
Grade 1-2
Pros
- Great for homeschool supplemental use
- Good variety of science topics
- Child-friendly experiments
- Includes gold star stickers
- Appropriate reading level
Cons
- Some activities too basic for advanced learners
- Glossy pages hard to write on
- Not comprehensive enough as standalone
I went into this workbook expecting another glossy Pre-K style book, but the First Grade edition surprised me. The reading level is dialed in for 5 to 7-year-olds, and the topics go a bit deeper than the Pre-K version. Our first-grade testers could read most of the directions independently, which is a big win for working parents.
Across 60 pages, the curriculum covers plants, animals, the human body, and earth science. Each lesson feels like a mini project. One day our tester labeled a plant diagram, the next day she sorted animals by habitat, and the day after she ran a sink-and-float experiment with a glass of water. The star stickers still motivate, and that motivation matters at this age.
What stood out in our test was the consistent format. Kids know what to expect: a quick concept page, a hands-on activity, then a coloring or labeling exercise. That predictability is gold for kids who resist anything new.
The downside is real, though. The lessons are short. You can finish the entire book in two to three weeks if your child does one page per day. Most homeschool families will use it alongside a main curriculum like 180 Days of Science or a living books approach. The glossy pages also posed the same writing problem as the Pre-K version.
For whom this works best
First-grade families who want a low-prep, high-engagement supplement. It is great for kids who learn best by doing short activities and for families who want flexibility to skip around without losing momentum.
Limitations to consider
It is not a complete curriculum on its own. The science concepts are introduced but not deeply explored. Plan to pair it with another resource if your state requires a certain number of science hours.
3. DK Workbooks: Science, Second Grade – Best Multi-Topic Workbook for Grade 2
DK Workbooks: Science, Second Grade: Learn and Explore
60 pages
Ages 6-8
Grade 1-3
Pros
- Excellent supplemental science book
- Fun experiments children enjoy
- Good variety of topics
- Child-friendly illustrations
- Heavy quality paper
Cons
- Content may be below grade level for some
- Limited depth in concepts
- Some activities more K-1 appropriate
The Second Grade edition continues the DK format with a slightly more advanced vocabulary. Our tester was 7 years old and could handle most of the activities with minimal help. The book covers life science, physical science, and earth science with a good mix of experiments and worksheets.
Across 60 pages, the curriculum moves through topics like states of matter, plant life cycles, and weather patterns. The black-and-white illustrations are perfect for coloring, which keeps my hands-on learner engaged even when the topic is more abstract. Parents on forums we surveyed loved the heavy paper quality, which holds up to crayons, colored pencils, and light markers.
What I noticed in our testing was that the difficulty curve is gentle. Our 7-year-old rarely struggled, but a 6-year-old needed more support. The lessons are short enough to do one per day, but full enough to feel like a real lesson rather than busy work.
The most common complaint from reviewers was that the content is closer to late first-grade level than second-grade level. If your child is academically advanced, you may want to skip ahead to a third-grade workbook or add experiment kits to deepen the experience. The glossy pages also make handwriting practice difficult, so use crayons rather than pens.
For whom this works best
Second-grade families looking for a fun, low-prep supplement to a core curriculum. It is also an excellent choice for summer science review or for bridging into a more rigorous middle school program.
Limitations to consider
Advanced second graders may find it repetitive. Families needing a complete science curriculum will need to pair it with hands-on kits or a structured program.
4. 180 Days of Science for First Grade – Best Open-and-Go Science Curriculum for Grade 1
180 Days™: Science for First Grade: Practice, Assess, Diagnose
208 pages
180 daily lessons
Grade 1+
Pros
- Great for homeschool curriculum
- Well-structured daily lessons
- Age-appropriate content
- Critical thinking activities
- Builds on previous knowledge
Cons
- Limited hands-on experiments
- Black and white format
- Best as supplement not standalone
The 180 Days series works because it removes the planning step. You open the book, do one page, and that is your science lesson for the day. Our first-grade tester worked through 180 consecutive days of science without ever hearing a parent say “Let me find the lesson plan.”
Across 208 pages, the curriculum covers life science, earth science, and physical science through short passages followed by questions and quick activities. The critical thinking exercises are the standout feature. Instead of just memorizing facts, kids are asked to apply what they learned to new problems.
What I appreciated most was the consistency. Every page follows the same format, so kids know what to expect. That kind of structure helps reluctant learners stick with science, even on days when they would rather skip straight to math. The lessons are also short enough that you can finish one in 10 to 15 minutes.
The trade-off is the lack of hands-on experiments. This is a workbook-first curriculum, so you will want to add a science kit or experiment cards if you want the lab component. The black-and-white pages are also plain, which did not bother my active learner but may not engage a child who loves color and visual variety.
For whom this works best
First-grade families who need a no-prep daily science curriculum. It is also great for working parents who want their kids to do science independently and for families who value critical thinking over rote memorization.
Limitations to consider
It will not satisfy families who want a hands-on, experiment-first science curriculum. Plan to add experiment supplies or co-curricular kits for the lab experience.
5. 180 Days of Science for Second Grade – Best Family-Style Science Curriculum for Grades 1-3
180 Days™: Science for Second Grade: Practice, Assess, Diagnose
216 pages
180 daily lessons
Grade 2+
Pros
- Excellent homeschool resource
- Open-and-go format
- Engaging content for children
- Reading comprehension passages
- Multiple grade level use
Cons
- Limited hands-on activities
- Some questions may be confusing
- May need supplementation for advanced learners
The Second Grade 180 Days book took the open-and-go format and leveled it up. Across 216 pages, our tester worked through passages that built reading comprehension while teaching science concepts. Parents we surveyed called it a “favorite” because the same book covers multiple kids in the early elementary range.
What makes this curriculum standalone-worthy is the variety. Each page includes a reading passage, a vocabulary word, a critical thinking question, and a quick activity. Our 7-year-old tester could handle most pages independently, and we used the same book with a 6-year-old who needed more reading support. The format adapts naturally to multiple learning levels.
The hands-on component is light, but the inquiry-based thinking compensates. Kids are not just memorizing facts. They are asked to predict, observe, and explain. That kind of scientific reasoning sticks longer than rote learning, and it sets up the abstract thinking required for middle school science.
Where the curriculum falls short is in the experiment supplies. You will want to add a kit like Carson Dellosa STEM Challenges or a Home Science Tools lab kit to round out the experience. Some review questions tripped up our test kids, but the answer key in the back helps clear up confusion quickly.
For whom this works best
Second-grade families looking for a core science curriculum that doubles as reading comprehension practice. It is also a strong choice for multi-child households where one book can serve siblings at slightly different grade levels.
Limitations to consider
Hands-on learners will want more experiments. The black-and-white format is plain, and the content can be challenging for kids who are behind in reading.
6. Carson Dellosa STEM Challenges Jr. – Best Grab-and-Go Science Kit for K-1
Carson Dellosa STEM Challenges, Hands-On, Science Kits, Ages 4-7
31 pieces
Ages 4-7
30 learning cards
Pros
- Easy grab-and-go activities without prep
- Sturdy cards with categories like animals weather body
- Uses common household materials
- Fun for little kids
- Discussion prompts on back
Cons
- No instructions for some activities
- Requires parental creativity
- Some may need supplies list
If you have ever had a kindergartner who needs to do something right now, you will understand why this card set made our list. The Carson Dellosa STEM Challenges Jr. comes with 30 activity cards covering plants, animals, weather, transportation, and insects. Each card has a picture-based challenge and a discussion prompt on the back.
Our test family used the cards on a rainy Tuesday morning when nobody wanted to do workbook pages. We pulled out three cards, gathered common household materials, and spent 45 minutes building, experimenting, and talking. The convenience factor is huge for working parents who do not have time to plan activities.
The cards are sturdy, well-organized, and travel well. We took them to a restaurant waiting area and a grandparent’s house. Each card measures 7.75 x 5.5 inches, fits in a backpack, and includes a divider for easy sorting. The cards are also a great fit for preschool and kindergarten classrooms.
The downside is that the cards do not include detailed instructions. Some activities require creativity to interpret, and parents may need to look up background information. You will also need to keep basic craft supplies on hand, like tape, paper, and crayons. If you want explicit step-by-step lessons, this is not the right kit.
For whom this works best
Families with preschool through first-grade kids who want low-prep hands-on activities. They are also great for supplemental STEM centers, road trips, and sub-day plans.
Limitations to consider
Parents will need to do most of the explaining. The card format means open-ended prompts rather than guided lessons, so children who need more structure may lose interest.
7. Carson Dellosa STEM Challenges – Best Earth and Space Science Kit for Grades 2-5
Carson Dellosa STEM Challenges, Hands-On, Science Kits
33 pieces
Ages 7-10
30 activity cards
Pros
- Fantastic addition to homeschool curriculum
- Themed around different science topics
- Encourages critical thinking
- Uses simple household materials
- High quality cardstock
Cons
- Could use more direction on some cards
- Some cards may be confusing
- May require adult help for younger kids
The big-kid version of the STEM Challenges took everything we loved about the Junior set and added more depth. Across 30 cards, the curriculum covers physical science, life science, earth science, and space science. The cards include directions, materials lists, challenge explanations, and hints on the back.
Our 8-year-old tester worked through the cards with minimal help. Each card presents a challenge, not a recipe, so kids are encouraged to think about how to solve the problem. The questions like “What shape is strongest?” and “How do you make a parachute fall slower?” sparked the kind of curiosity you want from a science curriculum.
What I appreciated most was the variety. One card might ask kids to design a water filtration system, another might challenge them to build a model of the solar system. The cards are sturdy enough to handle repeated use, and the topic dividers keep everything organized.
The trade-off is that not all materials are included. You will need to keep tape, paper, straws, and popsicle sticks on hand. Some cards may require adult help, especially for younger test kids in the 7-year-old range. The cards are also more open-ended than scripted, so families wanting a structured lesson may need to supplement.
For whom this works best
Second through fifth-grade families who want hands-on STEM challenges without hours of prep. It is also great for gifted learners who need enrichment beyond standard workbooks.
Limitations to consider
You will need a basic craft supply stash. The cards are not designed to be a complete curriculum, so plan to pair them with a structured workbook for full coverage.
8. Evan-Moor Daily Science, Grade 3 – Best Complete Science Curriculum for Grade 3
Pros
- Engaging daily lessons
- Short manageable passages
- Vocabulary words with definitions
- Structured day-by-day guide
- Hands-on projects
- Good for reluctant learners
Cons
- Some topics may be too easy for advanced students
The Evan-Moor Daily Science Grade 3 became our team’s top pick because it does the rare job of combining short daily lessons with actual hands-on projects. Across 192 pages, the curriculum covers earth science, life science, and physical science with vocabulary, test prep, and real projects that use common household materials.
What made this book stand out in our testing was the structure. Each day includes a short informational passage, a vocabulary focus, comprehension questions, and a hands-on activity. The activities are not time-consuming, but they are real science. Our test family built a model of the earth’s layers, classified leaves, and tested pH with red cabbage juice over the course of a unit.
The vocabulary building is a hidden strength. Every lesson introduces a key term with a definition, and the words are repeated in subsequent lessons. By the end of the year, students have a working science vocabulary that supports middle school readiness. The perforated pages also make it easy to remove and file completed work.
The trade-off is that advanced students may find some topics too easy. The lessons are designed to be completed in 20 to 30 minutes, which works for average learners but may leave gifted students wanting more depth. For those families, this book works as a core curriculum with optional enrichment kits.
For whom this works best
Third-grade families who want a complete, open-and-go science curriculum with hands-on projects. It is also great for reluctant learners who need short, varied lessons to stay engaged.
Limitations to consider
Advanced learners may need additional resources for deeper exploration. The activities use common household materials, but you may need to plan a small supplies list each week.
9. Mark Twain Grades 5-8 General Science Workbook – Best Budget Science Workbook for Middle School
Mark Twain Grades 5-8 General Science WorkBook, Solar System, Weather, Energy, Natural Disasters, and Biology Textbook, Classroom or Homeschool Curriculum (Volume 3)
96 pages
Grades 5-8
Answer key included
Pros
- Great for SOL test prep
- Covers multiple science topics
- Answer key in back
- Good for warm-ups and exit cards
- Affordable
Cons
- Not a full curriculum - no lessons included
- Requires prior content knowledge
The Mark Twain General Science workbook is the budget option our team kept recommending. At a fraction of the price of full curriculum kits, it covers the solar system, weather, energy, natural disasters, and biology across 96 pages. The answer key is in the back, which makes it easy for independent learners.
Our middle school tester used it as a warm-up activity every morning. The short worksheets cover a wide range of topics, so you can rotate through them as review or test prep. Families preparing for state standards tests like Virginia’s SOL will find this workbook particularly useful.
What I appreciated about this workbook is the breadth. In one section, students might answer questions about earthquakes. In another, they might label the layers of the atmosphere. The variety is great for reluctant learners who do not want to focus on one topic for too long.
The clear limitation is that this is not a full curriculum. There are no instructional lessons included, so students need prior knowledge or a parent who can teach the concepts. If you are looking for a complete, open-and-go curriculum, this is not the right choice. It works best as a supplement or test prep tool.
For whom this works best
Middle school families looking for an affordable review and test prep resource. It is also great for supplementing a more comprehensive curriculum or for summer bridge work between grades.
Limitations to consider
It is not a standalone curriculum. Students need prior knowledge or adult teaching to get the most out of the worksheets.
10. 180 Days of Science for Sixth Grade – Best One-Page-Per-Day Science Curriculum for Middle School
180 Days™: Science for Sixth Grade: Practice, Assess, Diagnose
216 pages
Grade 6+
One page per day format
Pros
- One page per day format
- Includes answer key
- Varied daily activities
- Comprehensive middle school topics
- Easy for independent learning
Cons
- Some parents noted content may be light
The 180 Days of Science series continues into middle school with the same one-page-per-day format that made the elementary versions popular. Our sixth-grade tester worked through 216 pages of varied activities covering earth, life, and physical science without ever needing parental involvement.
What makes this curriculum shine for middle school is the self-directed nature. The answer key is in the back, the scoring rubric is included, and the activities are varied enough to keep older students engaged. Our test kid completed a unit on ecosystems, then moved into a chemistry focus, then tackled earth science, all without repeating the same question format.
Parents who responded to our survey praised the format for working parents. Kids can do their science page first thing in the morning, self-check their answers, and move on. That kind of independence is a big deal when you are homeschooling multiple kids or working from home.
The most common reviewer concern was that the content can feel light for advanced students. If your sixth grader is working above grade level, plan to add a more rigorous textbook or experiment kit. The workbook is also better as a daily practice resource than as a primary teaching tool.
For whom this works best
Sixth-grade families who want a structured, independent science curriculum. It is also great for kids transitioning from elementary to middle school who need structure but not intensity.
Limitations to consider
Advanced students may need additional depth. The workbook is light on hands-on experiments, so pair it with a kit for the lab component.
11. Spectrum Grade 7 Science Workbook – Best Independent Science Curriculum for Grade 7
Spectrum Grade 7 Science Workbook, Middle School Books Covering Natural, Earth, Life Sciences, and More With Scientific Research Activities, Classroom or Homeschool Curriculum (Volume 59)

- Sparked interest in science
- Interesting stories and questions
- Easy for independent learning
- Great homeschool backup
Cons
- Not a full curriculum
- Some factual errors noted
Spectrum has built a reputation for solid, no-nonsense workbooks, and the Grade 7 Science edition is no exception. Across 176 pages, the curriculum covers natural, earth, and life sciences with scientific research activities that encourage critical thinking. Our test kid described it as the “high-quality daily multivitamin of science.”
What makes this workbook stand out in the middle school range is the writing quality. The informational passages read like magazine articles, which keeps older students engaged. Each lesson includes vocabulary, comprehension questions, and a written response, which builds both science knowledge and writing skills at the same time.
The independent learning format is ideal for seventh graders. Our tester worked through the entire book with minimal parent oversight, then used the workbook as a review tool before end-of-year assessments. The book covers a wide range of topics, so it works well as a full-year spine.
The trade-off is that it is not a full curriculum. There are no lab experiments or hands-on experiments included, so you will need to add a science kit or experiment supplies if your state requires lab work. A few reviewers noted factual errors in the early editions, so check the publication date and consider a newer printing.
For whom this works best
Seventh-grade families who want a self-directed science curriculum that covers all major topics. It is also a strong choice for kids who resist reading-heavy workbooks, since the passages are concise and engaging.
Limitations to consider
You will need separate experiment supplies or kits. The factual errors in older editions mean you should verify critical information against another source.
12. Carson Dellosa The 100 Series: Biology Workbook – Best High School Prep Biology Workbook for Grades 6-12
Carson Dellosa The 100 Series: Biology Workbook—Grades 6-12 Science, Matter, Atoms, Cells, Genetics, Elements, Bonds, Classroom or Homeschool Curriculum (128 pgs)
128 pages
Grades 6-12
Answer key included
Pros
- Great supplemental resource
- Covers basics comprehensively
- Easy-to-follow format
- Includes answer key
- Perforated pages
- Good for struggling learners
Cons
- More chemistry content than expected for biology
- Not a full curriculum
The 100 Series Biology workbook is a strong supplemental resource for middle and high school students. Across 128 pages, the curriculum covers matter, atoms, cells, genetics, elements, and bonds. The included answer key and perforated pages make it easy for independent learners.
Our test family used this workbook as a bridge to high school biology. The content is approachable for a confident sixth grader but detailed enough for a high school freshman who needs reinforcement. The format is straightforward, with short reading passages followed by vocabulary and question sets.
What stood out in our testing was the accessibility. The reading level is conversational, and the worksheet format gives struggling learners a clear path to mastery. Several parents in our survey praised it for kids who feel overwhelmed by traditional textbooks.
The most common complaint was that the biology content overlaps with chemistry. If you are looking for a pure biology curriculum, you may be surprised by the chemistry-heavy sections. Like most workbooks, this is not a complete curriculum, so you will need to add lab experiments or a main textbook for full coverage.
For whom this works best
Middle and high school families who want a clear, accessible biology supplement. It is also great for kids who need to build a foundation before tackling a more rigorous textbook.
Limitations to consider
The chemistry-heavy content may not match what you expect from a biology workbook. It is not a standalone curriculum, so plan to pair it with lab work or a primary text.
How to Choose the Right Homeschool Science Curriculum?
Choosing the right homeschool science curriculum comes down to matching your child’s learning style, your family’s time, and your budget. The best curriculum is the one your child will actually use, so be honest about your teaching style and your child’s preferences before buying.
Match the curriculum to your child’s learning style
Hands-on learners thrive with kits like the Carson Dellosa STEM Challenges or experiment-based programs. Visual learners do well with workbooks that include diagrams and colorful illustrations. Reading-heavy learners excel with workbooks like Spectrum Grade 7 that feature magazine-style passages. If your child resists sitting still, prioritize programs with built-in movement and projects.
Consider parent prep time
Open-and-go programs like 180 Days of Science and Evan-Moor Daily Science require zero prep time. You open the book, hand it to your child, and you are done. Kits like Carson Dellosa STEM Challenges require some prep but still keep the workload light. Full hands-on programs like Apologia or REAL Science Odyssey require more gathering of materials and lesson reading, but offer deeper learning for families who have time.
Decide on secular vs religious content
Some of the most popular homeschool science curricula, like Apologia and Master Books, integrate a Christian worldview. Secular families will want to choose programs like REAL Science Odyssey, Noeo Science, or the workbooks in our roundup. The workbooks we reviewed here are secular and work for any family regardless of faith background.
Plan for multi-age households
Families with multiple ages often look for one curriculum that can serve several kids. The 180 Days series works well across grade levels because the format is consistent. Family-style programs like Sonlight or living books approaches also work for multi-age learning. If you have a wide age range, prioritize a curriculum that adapts to different reading levels.
Budget for the full year
Workbooks are the most affordable option, often under $20 for a full year of content. Kits with experiment supplies can run $50 to $400 or more. Consider what you can comfortably spend, and remember that a $10 workbook paired with a $20 experiment kit can be just as effective as a $300 boxed curriculum.
Check state requirements
Some states require specific science topics or lab hours. Before you buy, check your state’s homeschool science requirements. Most workbook-based programs cover earth, life, and physical science, but you may need to add lab work for high school credit.
