Forensic Entomology

Forensics is a topic students LOVE to learn about, so even if you don’t teach an entire course on it, throwing in a few lessons at the end of the semester is always fun. There are a ton of labs you can do ranging from blood spatter, fingerprinting, analyzing hair and fibers and impression evidence. There are a bunch of free lab downloads at The Science Spot’s website (especially great for middle school grades).

Last year I wanted to add entomology to my forensics unit. I could have ordered maggots online, but if your school is anything like mine, you place an order and cross your fingers it arrives within the next 4 months. Since I didn’t plan ahead that well, I needed them within the next week.

If you want to get your own maggots growing, it’s not difficult to do. All you need are the right environmental conditions. Flies like to lay their eggs in dark warm places (like inside of a decomposing body….). The easiest way to replicate these conditions is to buy a rotisserie chicken at the grocery store, eat some chicken for dinner, and save the carcass. Check out the video below with more details and how you can use them with your students.

When we learned about entomology I had students read this article I wrote up on Body Farms. If you aren’t familiar with body farms, they are outdoor research labs where donated bodies are left do decompose in different scenarios and conditions. Scientists use this information to help determine estimated times of death. It’s a little gross, but fascinating.

Have any questions I didn’t answer in the video? Leave them in the comments and I’ll get back to you!
