After learning about how cells divide to produce gametes (meiosis), and how genetic traits are passed along, we turned our attention to the process of sexual reproduction. The lesson began with an entry task challenging students to connect their understanding of meiosis with what they might have previously learned about fertilization. We then watched a video which explains the process of fertilization (below). For the remainder of the lesson, students read from the BSCS biology textbook and completed a worksheet.
