The adventures of a fourth grade teacher in East Central Illinois.

Teaching Genetics

I have been reading the book Wonder to my class. It is a fantastic story, and my students are really enjoying it. For those who may not know, Wonder is the story of August Pullman, a ten-year-old boy who was born with a severe facial deformity known as mandibulofacial dysostosis. The story focuses on August’s first year in school and how his classmates respond to him. It is written in multiple voices, with each narrator being selected from the children of the story.

Today we were reading the portion that tells the story from August’s older sister’s point of view. Olivia (Via, as she is called at home), is very protective of her brother but she is also trapped in the desire to be known as someone more than “August’s sister.” As we read, there was a section that focused on the genetics of Auggie’s deformities. I was reading aloud, but I realised that many of the students probably didn’t know what the words I was saying even looked like, let alone what they meant. So as I read, I also wrote on the whiteboard and, in the process, found myself introducing very basic genetics to my fourth graders!

We were discussing words like genechromosomedominant traitsrecessive traits, and mandibulofacial dysostosis. We also talked about Punnett squares and how genetic traits, such as straight or curly hair, eye colour, attached of unattached earlobes, or whether or not a person can curl his or her tongue, are passed on. And the great thing about it all was that I had everyone engaged in the conversation! I explained that what we were talking about was really high school and even college-level biology, but because it was in the story, I wanted them to have an idea about what these words meant.

I love when we have these impromptu lessons that aren’t specifically a part of our prescribed curriculum! It is one of the things I love most about teaching fourth grade: when I allow students to ask questions, we may go way off topic, but we are learning. Together.

And that’s just awesome.
