I have to do presentation on amphibians this coming Wednesday, and the presentation has to be 15-30 min. I have to do an activity with the class, and I have no idea where to start. I have everything for my report part of it. However that part isn't supose to last as long. I'm working with 10th-12th graders.
Students like to see the real thing.
Second to having actual critters you may want to have many pictures of all the various amphibains. It also might be good to talk about that make an animal and amphibain and talk about the internal structures. After covering those three things you should have taken up the time you need. You could also talk about habitat. If you needed more information for your presentation.
