If your summer plans, like ours, include going to the ocean, you may be interested in this video from Reactions about how seashells are made. In How Seashells Are Made viewers learn that seashells are made of 95% calcium carbonate and 5% protein and sugar. The video doesn’t stop with just listing the components of seashells. By watching the video viewers can learn how calcite and aragonite are layered in seashells to create a hard shell.
I’ve never been a “lay on the beach” kind of person. I’m the person you’ll find wandering and looking at neat things that get washed up on shore. My daughters are the same way. If you have students that like to wander and collect seashells, use that curiosity as a segue into a science lesson about how seashells are made. This video is a great candidate for inclusion in an EDpuzzle lesson in which you add questions and your own clarifying remarks for students. Watch my EDpuzzle tutorial to learn how to add questions to an existing video.
