Science 9 – Having starting looking at mating and fertilization, I thought today would be a great time to show a video on mating from the new BBC series “Life Story.” The series has great videography and this episode is right on track for the science 9 course. The students get to see the advantages and disadvantages of internal and external fertilization and the different ways that animals mate. But most importantly, the show is just COOL. Above, check out the amazing pattern created by a pufferfish for attracting a mate.
