Homeschool Science Units and Curriculum

We have close to a hundred science posts, if not more! So, I made this page to help you find some of the science resources, notebook pages, and hands-on activity ideas we have here on the blog. The table below organizes all of our science posts.  I hope it’s helpful! If you ever have any questions, feel free to drop me a line. Plus, if there’s a topic you need – feel free to reach out to me and I can try to add it to my to-do list!  liesl at homeschoolden dot com.  You can also leave a comment/request in our free FB community Homeschool Den Chat Group.

Below the science unit chart, you’ll find a couple of quick videos including one about Homeschool Science in the Elementary and Middle School Years. It highlights some of the activities and experiments we’ve incorporated in our science units over the years.

How do we know what science units to cover from year to year? I created a Homeschool Science Unit Checklist for Elementary and Middle School that I think about as we move from unit to unit. I have a general goal of what I’d like for the kids to have covered K to 8, but we’re also flexible and go off on tangents when it’s warranted! It many of the units we hope to cover in elementary and middle school.

ScienceHomeschoolChecklistBelow are some of the units we’ve covered in our homeschool.  Along the way, I’ve made lots of notebook pages for the kids and we’ve done tons of hands-on activities. Some of our packets and notebook pages are for sale (generally between $4.00 and $9.00), while others such as rocks and minerals worksheets and weather packet are free.

I hope you find some posts that help make science come alive for your family!! ~Liesl

PS-This chart is always a work in progress!  You know how that goes! 🙂

Latest update, June. 2018: Here are our most recent science packets…

Scientific Classification and Taxonomy: This past fall, we did an in-depth study of scientific classification and taxonomy  (You know, kingdom, phylum, class, order, family, etc!) We spent a lot of time really learning about difference in structure and form among the phyla… what is the difference between platyhelminthes and annelids, for example! My kids can tell you! We also did some simple dissection at the end of the unit.  (If you have younger kids, you would probably be better off to start with the Animal Unit which touches on classification, but goes over broader differences between vertebrates and invertebrates, which animals have feather/fur/skin; insects vs. spiders; domesticated vs. wild animals; animal tongues; animal homes, etc. )

I suggest that you use this Scientific Classification packet with middle school+. The Animal Unit is better with younger (elementary) students and we did that unit a few years before we did this one. 🙂

This year, we did a unit on Chemistry, going into more detail about the Periodic Table, ionic & covalent bonds, Bohr Diagrams, Lewis Diagrams and more! The kids really liked working with the chemistry cards and said those really helped them understand electron structure! The cards are included in the packet as is the interactive notebook activity, worksheets, and pictures/instructions with the hands-on activities we did. (Suggested ages: middle school+  — My kids were 10, 12 & 14 when we did this unit).

States of Matter Unit and our really fun Electricity and Circuits Unit, with all its hands-on activities!

Physical and Chemical Properties of Matter WorksheetsThis year I also did huge updates to our Earth Science Packet (adding in over 50 pages!). I added in pictures in the chart below. There were also new updates to the Simple Machines Packet, the Animal Packet, the World Animals Packet, the Biology Packet (which is more of an ecology unit) and the World Facts Packet (which is more of a geography packet… but I added in a huge section on geographic features like atoll, isthmus, etc. .. which relates to Earth Science, right?!).

This year, we also studied the Digestive System again, so that packet also got a huge update (last year we studied the Circulatory System). We spent a lot of time talking about the parts of the small and large intestine as well as the organs such as the liver, gall bladder, pancreas and their role in the digestive process. Not only did I add new notebook pages and interactive notebook pages… but I also added in an entire section on Nutrition – we spent time learning about the role fiber plays in your diet and also learned about some of the important vitamins we need.

Rainforest Unit Worksheets and ActivitiesRainforest Animals Montessori 3-Part CardsThis spring we spent time talking about Life Cycles again.  I also made a new Life Cycle Packet — which helps kids become familiar with the different stages in the life cycles of the chicken, sea turtle, frog, mosquito, butterfly, dragonfly, bee, mouse, and ladybug. There are cut-and-paste activities, writing paper, a game, make-a-spinner activities and more.

I’m still in the midst of writing up more hands-on activities (and doing things with my daughter to test them out!).

P.S. Someone asked me for a printable list of our Science Packets and Bundles. It also includes a list of some of the free resources we have here on the blog. Here’s a pdf you can download and print out.

We did a Physics Unit a number of years ago (when the kids were 8, 6, 4). This post has some of our hands-on physics activities after we had learned about Newton and read through our physics textbooks.

Digestive System Unit: We had such fun with this unit. We did hands on activities to see how the digestive tract works (how nutrients pass through), made “fake”vomit, measured out the length of the digestive system and more! We broke this unit into three sections:

  • We did a unit on the Skeletal System – We studied the bones of the body when the kids were younger (see our preschool science posts), but this time we talked not only about the different bones of the body, but also their function, how they grow and repair themselves, how the skeletal system is divided (axial, appendicular), joints and more.Skeletal-System-Worksheets-Skeleton-Lapbook

We followed up our States of Matter Unit, with a study of the physical and chemical properties of matter which was geared more for my 11 and 13 year olds.  In this unit, we went into a lot detail about density and did a number of hands-on activities to determine the density of different materials.


My older kids did a study of the periodic table:

While my younger daughter used Real Science-4-Kids Chemistry pre-Level I (affiliate link) and did a lot of science experiments to go along with that.

Here are some of our other chemistry posts (from when we studied chemistry a couple of years ago):

Homeschool Den Video Post: Science in the Elementary and Middle School Years

This is a video post about Homeschool Science in the Elementary and Middle School Years. It highlights some of the activities and experiments we’ve incorporated in our science units over the years.

Homeschool Den Video Post: Science in Early Elementary

How do I start teaching science to my kids?  This is a very different answer if your kids are K-2 than if they are a bit older.  Here are some of the science topics you might want to consider if your kids are in early elementary. I put together a video of some of the activities we did when the kids were in early elementary.
