The Life and Times of Gregor Mendel is an activity to engage students in working with the background of his studies on heredity. This activity provides a unique way to group students by working with the clock and making appointments with other students which forms five different groups for each student. Every time on the clock has a set of questions dealing with Gregor Mendel’s biography. The outcome of this activity gives students the opportunity to learn more about Mendel and his life. This activity includes teacher instructions, student activity sheets (clock and problems) and an answer key.
