California Fish

We're Milan and Harison, and we love going to the ocean. We like to learn about the animals that live off the coast of Los Angeles, and a great place to do that is the Long Beach Aquarium of the Pacific. Our favorite exhibit there is the shark and ray pool. You can see them up close, and even touch them. We think it's interesting to watch a ray eat, with its mouth on the underside of its body. We got to wondering: How does a fish's mouth type affect what it eats?

How would you investigate this question?
Design an experiment that will provide a possible answer to Milan and Harison's question. Come up with a plan for deciding which kind of fish you will observe, how you will observe them eating, and so on. Prepare a data table that allows yout o record differences in the feeding habits you see. Describe your investigation in your notebook and discuss it with your teacher, or go to California Fish to learn what Milan and Harison discovered.
