Special Science Teleclass: Marine Biology

This is a recording of a recent live teleclass I did with thousands of kids from all over the world. I’ve included it here so you can participate and learn, too!

If you love aquariums, underwater volcanoes, robots and science, and you also love to watch everything that swims, crawls, or moves in the sea, then this is the area of science for you. We’re about to see and do the kind of science that was not in your typical textbooks. Most of these discoveries were made by accident, and everything we’re about to see is only a tiny fraction of what is really down there in the ocean.
