When I think about 7th grade science, I think “dissections.” What about you? Did you enjoy them, hate them, avoid them?  We were blessed to be in a school where we could work on dissections individually or in pairs. I never minded doing dissections and I knew since beginning this journey that dissections were one of those “public school experiences” I wanted my home schooled kids to be able to have. Aren’t my kids lucky?

Our first home dissection was an owl pellet dissection a few years ago. In fact, I think that was actually my first experience with Home Science Tools, too. The kids loved that one! We waited a little while (for them to grow a little older) and last week we dove into the REAL dissections with a “Mammal Organs Dissection Kit“— compliments of Home Science Tools so that I can show you all the pieces, tell you all about it, and let you see it “in person” so to speak.

Inside the Home Dissection Kit


I know many of you are squeamish – don’t be! Come with me and take a peek inside the box.

~ All of the “parts” come enclosed in vacuum sealed baggies, labeled and ready to go.
~ In addition to the organs you’ll find instructions for each.
~ Some dissection kits come with tools, the Mammal Organs kit doesn’t. (I knew that was okay because I knew that grandma had what we needed! But if you don’t, you’ll need to make sure you get some tools, too.)
The kit does, however, come with some nifty Styrofoam trays to perform the dissections on and protect your table. Bonus points for the Styrofoam trays. =)


Back to the instructions.. this is great for the mom who is willing but doesn’t know what to do. You don’t have to! (And that was me, willing but uncertain.) The directions tell you step by step what to do and how to do it.

Depending on the age of your children, they might have some large vocabulary words you’ll want to look through beforehand. I counted that a benefit as my children learned what “anterior,” “posterior” and “sagittal” meant! The directions for the cow eyeball and the sheep heart were the most colorful and easy to understand and exceptionally helpful.

Performing Your Home Dissection


Before you begin, you’ll want to make sure that you have everything ready to go. You’ll need:

  • plenty of time
  • a well ventilated area
  • a scalpel, small scissors, probe, tweezers, etc.
  • some protective gloves, (protective eyewear would be good, too)
  • some newspaper to lay down on your work surface
  • a few small trash bags handy
  • your dissection kit with directions, parts and trays

Read through the directions once or twice to make sure you understand what you need to do. Take the opportunity to discuss new words with the kids or review some vocabulary words they should already know but may have forgotten. Now you’re ready to begin. Let’s go!


Let’s Go on an Adventure with Home Science Tools

I urge you to cast your reservations aside and take a huge leap toward earning a “Seriously Cool Mom Award.” You can do this. Let’s roll up our sleeves and take a journey through the cow eyeball, shall we?

The cow eyeball was hands down the home dissection that everyone loved the most. The kidney and brain were interesting, the heart was too, but the favorite was the eyeball. (Was it the gross factor? To some extent, perhaps..)


Before you begin dissecting, start with observing. What do you see? How does it feel? What is this down here or that over there? Take plenty of time holding it and passing it around so that everyone has a chance to examine it.


The really cool thing about dissecting these animal organs is that they are very similar to the anatomy of our own organs. Not only did we get to observe the animal anatomy (as we are studying land animals in science this year) but we also got to observe how our similar human anatomy works (which we studied before this.)

As we examined the cow eye, and all the way through the dissection, we observed and discussed similarities and differences between the cow eye and a human eye. We found the optic nerve coming off the back of the eyeball, we found the sclera black instead of white, and so on. Once you’re done observing, you’re ready to take a look inside.


Our cow eye was really well preserved because the vitreous humor inside (the clear gel, aka, the gross stuff) was still clear and gelled. Inside the eye we were able to observe the shiny inside of the cow’s eye (that animals have and is responsible for “eye shine” at night), called the choroid coat.


We also found a teensy hair of an optic nerve sticking up inside the eye ball (TEENSY!,) found where the vessel attaches at the retina (causing the blind spot,) observed the muscles of the iris, and examined the cornea.

By far, the coolest, neatest, most amazing part was holding the lens in our hand. We all got a thrill out of setting it on the newsprint to watch it magnify the letters. We were all amazed at the Skittle shaped disc that floats in our eye behind the iris, bringing our world into focus. God’s creation is amazing!


Clean up and Safety for Your Home Dissection

You might be concerned about the preservative – what about the formaldehyde?? Home Science Tools uses a low odor formaldehyde (though we noticed some parts were stinkier than others.) Still, this is why you need a well ventilated area, gloves (and preferably eye goggles.) We discouraged the kids from touching the pieces without gloves, and from touching other things (phones, cameras, their face,) while they had their “contaminated” gloves on. We wanted to be able to experience this home dissection for ourselves, but we also wanted to be safe and smart, too.

Safety and easy clean up is also why we kept several small plastic bags handy. As we trimmed away pieces for the dissection (eye muscle aro eye ball for example,) we placed it off to the side in a bag. When we were all finished, we added the rest of the specimen into the bag as wellRolling everything up in the handy newspaper we covered our table with, we tied the entire roll up into a second trash bag to discard.  The last step for safety and clean up is to wash everything down – table, tools, hands and arms, with a good dose of soap and water.

For more information about storing and discarding, check out this list of FAQ’s at Home Science Tools.

After the Dissection


Are we going to do another? Yes we are.

All three of my kids are agreeable and Drama Queen is actually quite excited and can’t wait to do another. She circled almost every other dissection kit in the catalog. ; ) We’ll wait a little while but I hope to do at least one a year.


In the mean time, I wanted to take a little time to “cement” what we had observed in our dissections. When we were finished I asked questions about what they saw, what they remembered or had forgotten, what they learned. I quizzed them on the new vocabulary words and what we had seen.

A few days later I printed a few coloring pages and we went over it again, drawing on our memory from both the dissection and our science class from last year as we labeled and colored. We may forget some of the terms and vocabulary again but I have no doubt that the memory of the dissection will stick.

(P.S. If you’re wondering: The two books in the picture above are our Apologia Anatomy Book and the The Kingfisher First Human Body Encyclopedia.)

Do you feel empowered yet?

I hope I’ve given you a little bit of confidence in the home dissection department. If I can do it, you can do it!

It is true that we all went over to my mom’s house and that she and I both took turns cutting and manipulating – that was mostly because I needed a second set of hands for taking pictures, and because she had the scalpel, and because she wanted to do it, too. I would have completely been able to do this on my own, and you can, too. However, if the “safety” of doing it with a friend is what you need to help get you through this, go for it!

Hey, y’all! I’m Amber and I wear many hats. I drink a ton of coffee and I’m constantly sweeping crumbs off the floor. After 18 years of homeschooling, I’m getting close to graduating my third child and now we are starting over at preschool with our fourth, Lil Miss Mouse. She keeps us young and she’s the main reason for my excessive coffee consumption. Drink up!
