I was first introduced to the idea of genetics when I was a high school freshman in biology class. I found the idea of recessive and dominant traits fascinating. It was also reassuring that the things that made me weird (being able to roll my tongue, my hitchhikers’ thumb, being the only blue-eyed child in my family) were not really my fault. They were my grandmother’s fault.
Now, I find Mendel Squares fascinating; my students, not so much. However, they are of an age where things like hair color, eye color, and all those inherited traits are becoming more interesting to them. Most of my students are also farm kids and so the breeding of animals is something talked about, even if the logic behind it is unclear.
Enter a great game that I was only able to touch upon in an earlier post: Thingdom. A game created by The Science Museum in London, Thingdom was created to teach children about genetics in a very approachable and fairly age-appropriate way.
The game is simple enough. You create a small, multi-colored blob-shaped creature called a ‘thing’ and then slowly raise it up like a virtual pet; feeding it, petting it, and making it dance. The real fun happens at around 5 minutes when the little bugger screams out: “I WANT TO MATE!” With cute little hearts all around.
After the giggling has passed, the science starts. You are challenged to breed your ‘thing’ with other things in order to get a desired trait from the babies, such as stripes, blue color, or size. Children are shown how recessive and dominant traits combine to increase the chances of traits. Students are not allowed to proceed until they have completed such tasks as breeding a thing to have large size, fuzzy fur, or spots. This explains to students in a fun, age-appropriate way how children inherit traits from their parents. It also helps explain such questions as how human meddling created both the Great Dane and the Chihuahua.
