This week the 7th and 8th graders at CHA got to dissect frogs! First we examined the exterior structures of the frog and talked about some of the specialized traits they have, such as an extra eyelid. The students were particularly interested in how the frogs eat. By examining the interior of the mouth, students were able to see how the tongue functions to catch food. It is actually attached to the front of the lower jaw! We also got to see how frogs use their eyes to help them swallow their food.
Next we moved on to the interior organs. Students carefully opened up the body cavity to reveal the organs. We walked through each organ discussing their function in humans and any differences in frogs. Then we attempted to determine if each frog was a male or a female. It is much more difficult to determine in frogs than humans! Ask your student what they found to be the most interesting structure in the frogs!
