How does one get mom's curly hair and dad's brown eyes? Can everyone in one's family fold their tongue?
This unit introduced students to basic ideas of genetics, such as traits, DNA, types of cells, chromosomes, mutations, and how traits are passed on to them from their parents. Students surveyed the class for common traits, made a time line, developed a family tree, and learned about Gregor Mendel.
Here are some of the timelines and family trees created by the students. Also, our school secretary, Fran Townsend, whose avocation is genealogy, was a guest visitor to our class. She shared her many stories of her family history and her extensive family tree.
