Science - Lesson #7: Male Reproduction

Lesson 7: Male Reproduction

Investigate the causes behind the global decrease in sperm count.

I am successful when I can...

1) Engage with a scenario by asking questions about the impact of vinyl chloride and other environmental pollutants on sperm count.

2) Explore by analyzing and intepreting dats trends in global sperm counts over time.

3) Explain how bioaccumulation of microplastics might impact the male reproductive system based on evidence from the article.

4) Elaborate by extending my explanation to consider how bioaccumulation might affect the townspeople of East Valley, Ohio

5) Evaluate by reflecting on my learning and identifying areas where I need to improve my understanding of bioaccumulation and reproductive health.
