The "Race and Science" lesson is important because it arms learners with a better understanding of what race is, what it is not, and that leads to a better understanding of human nature. Personally, learning this information completely changed my point of view. I know now that Race is not biologically real, which was also reinforced by the information provided about characteristics of people based on their proximity to the equator.
The N-word lesson is significant because it gives an in-depth understanding of the term by explaining exactly what it means and describing the various exchanges and those relationships. The lesson impacted my stance on the subject because it helped me to acknowledge the meaning of the word, where this comes from and I gained a better sense of how different people use it in different situations.
