This one-hour lesson plan outlines teaching the male reproductive system to 10th grade students. The objectives are for students to identify parts of the male reproductive system and their functions, describe the pathway of sperm from production to ejaculation, and appreciate the role of the male reproductive system in human reproduction. The lesson uses videos, diagrams, group work, questioning, and demonstrations to help students learn about the male reproductive organs and their functions, as well as how sperm is transported from the testes to fertilization. The plan includes formative assessments to evaluate student understanding.
