The Secret Lives of Baby Fish is a cute and informative TED-Ed video that I watched over the weekend. The video explains how coral reef fish reproduce, grow, and survive. Through the video viewers can also learn about how new research is changing marine scientists’ understanding of some aspects of the geographical distribution of coral reef fish.

While I enjoyed the video because it is well-produced, I was equally happy with the accompanying questions found on the TED-Ed site. Instead of just asking “did you pay attention?” types of questions, the first three questions ask students to think and use the information they just heard.
