Three Kids, a Dead Raccoon, and My Crockpot: A Photo-Essay
I was out of town giving a public talk last week when I got this picture along with a text from my husband: "Zooarch consult plz."
That's my 8-year-old on the right along with their BFF. They were traipsing through the small patch of woods behind our house and found some... dead stuff. Squinting at my phone, I typed back that there was a turtle and maybe a small dog or something, but that I'd check it out when I got home. And to wash their hands well.
The kids gathered the bones-and-fur mess and tied it off in a plastic bag.
Once I got a look at it, and posted to Facebook for a consult, I realized it wasn't a dog but rather a raccoon. The next step was to separate the raccoon from the turtle shell and pick off the gross decaying fur. So I brought home some nitrile gloves from my lab.
The 8yo liked this part, and was excited to find some vertebrae still articulated:
The 8yo put all the bones into the crockpot that I brought home from my lab as well (which we keep for the express purpose of defleshing stuff that, well, still has squishy/hairy bits on it). The 8yo filled it about 2/3rds of the way up with water from the garden hose (which they wanted to put in the watering can for some reason). Then, we had to add detergent. Biz was recommended to me by our resident faunal expert in the department, so I bought a small amount of it at Publix.
At this point, my 4-year-old wanted to help out. After the 8yo dumped in the detergent, they both took turns gently stirring it. (The 4yo by the way, was quite disappointed in the raccoon - they really wanted to macerate a bat, to see how its wing looked on the inside. But that's not gonna happen because of the risk of rabies.)
We put the lid on, turned the crockpot on to the low/4-hour setting, and left it alone.
Since we didn't start this quite early enough in the day, by the time we turned the crockpot off, it was getting dark. I decanted the sudsy water off carefully, and then dumped the rest of the water-and-bones out onto the cement patio. We collected the bones and set them on the metal table outside, and I let the 8yo and friend scrub the bones with old toothbrushes to get the remaining fur off.
Once the bones were cleaned, I tossed them into a disposable tupperware bowl, dumped in all the hydrogen peroxide I had (maybe 1.5 cups), and topped the bowl off with water and capped it. I didn't take any pictures of this, but we left it on the kitchen counter for like 3 days, swirling it occasionally.
When we were happy with the color, we dumped the bones out of the hydrogen peroxide solution and let them dry on the table outside.
After the bones were dry, I printed out two diagrams of raccoon skeletons. I gave those to the 8yo along with the clean, dry bones, and let them puzzle out where they all went.

This is what we ended up with, once I helped identify and side the bones. (Those of you with better faunal anatomy skills, don't yell at me! I totally punted on the metatarsals and tarsals(?) but think I did OK on the major bones.)
The 8yo wanted to label the bones and put them in labeled boxes or bags, so I helped by giving the correct plurals where relevant.
And that's it! We finished labeling the bones this afternoon, and now they're in little bags and boxes, waiting for... well, who knows. I'm interested to find out what the 8yo wants to do with the raccoon!
So, if your kid brings home a random dead thing, all you need are a crockpot, some detergent, and hydrogen peroxide, and... voilà ! A STEM-worthy project.
