Skin colour matters to our students. As much as we’d like to pretend otherwise, it’s still something that plays a big role in how they define each other and how they define themselves. I’ve found that my students are fascinated by the brief discussion we have about skin colour when looking at melanin in the P2 unit of the 21st Century Science course. It’s refreshing for them to take a scientific look at the issue and it’s definitely one of the “relevant” bits of the course that actually makes an impact on them. This video provides an in-depth look at the science of skin colour. It’s probably too long to use in class, but definitely worth pointing out to students who might be interested.
