Description

Every time I teach reproduction, I always get the same question from students: how do twins form? I made this activity to help my own students understand this interesting natural phenomenon. In the activity, students will see how identical twins form, and how fraternal twins will form. They will use guided directions to cut and paste appropriate stages of development into boxes on their lab report and will finally see that identical twins are the product of a single sperm and egg and that fraternal twins are really not different than any other siblings. There are analysis questions as well. The preview shows what the entire activity would look like after the students would have COMPLETED their lab reports.

Keywords: twins, lab, hands on, fertilization
