Anyway, we did this at the end of our Ocean unit. After discussing the ocean and its many inhabitants, we talked about the ways that people learn about the ocean. Of course, there are many ways, but the two that we discussed in depth were scuba diving and snorkeling. We talked about how scuba divers wear a special suit and they have to bring their air with them because they are going under the water where you need gills to breathe and people have lungs! We talked about how the flippers that scuba divers put on their feet copy those of many water animals. The flaps between their toes allow them to swim much swifter and more smoothly through the water. We compared scuba diving to snorkeling and discussed the differences. Many of my students were familiar with snorkeling gear which is interesting since we live in the middle of corn and bean country here!
