Open Ended Amphibian Questions?

For my class project in high school biology, we are doing an activity along with a presentation on amphibians. We decided to go with a beach ball and write open ended questions on the parts of the beach ball and if they got the questions right they would recieve a piece of candy. I am wondering if someone could give me some good open ended questions that can have many answers about amphibians their subclasses habitat characteristics all of that stuff. Thanks
