Your students will enjoy this activity as they need to poll their classmates. What traits are prominent in the classroom. Can your peers curl their tongues? About 81% of people can curl their tongues. More females than males can do it. Their ability to do it will depend on if their intrinsic muscles will allow it or not. Are their thumbs straight or do they have a big curve? It is believed that this is controlled by a single gene. Record classmates names and their answers on this ready made sheet.
