We recommend that you use one pipe cleaner for each of these sections. If you look carefully at the template, you'll see that the skeleton consists of different shades of grey, dividing it into six sections. We're going to use the pipe cleaners to make a simplified model of the skeleton. They also protect vital organs (like the brain) from mechanical shock, make blood cells and store special minerals. The bones in the body are not only there to support the muscles when the frog is moving about. The frog skeleton also contains a lot more cartilage than yours to make it lighter. The bones of the second half of the spinal chord are fused together to form a rod (called the urostyle) between the sitting bones that propel the frog into the air.
We added some fun facts and useful links for the curious.īy just looking at a frog's skeleton, you can already guess what is its favourite way of moving around – jumping! Powerful hind legs dominate the skeleton.

It is our hope that teachers and pupils alike will be inspired by this Instructable on how to make your own ready-to-dissect frog. She would have loved to give her students more practical experience with animals, but ethical considerations and limited resources make it impossible for her to expose her students to anything more hands on than a YouTube video.Īs an engineer, an occupational therapist and a zoologist, we immediately put our heads together to design the perfect solution – an educational tool that would allow anyone to perform a virtual dissection of a frog! And the best part? It can all be done with bits and bobs lying around the house, with no background knowledge of frog anatomy whatsoever. However gross it might seem, this frog dissection is the starting point for understanding how our bodies work.Ī friend of ours, a high school biology teacher in a small rural town in South Africa, recently lamented the fact that this iconic activity is no longer part of the school curriculum. What is one of the first things that come to mind when you think of a biology classroom? To some, it might be the dreaded frog dissection, a rite of passage for students of the life sciences the world over.
