Shape of Life is a series of FREE classroom videos based on an original PBS Series. Explore the beautiful evolution of the animal kingdom on planet earth. This series is for learners and educators investigating the way animals thrive and the innovative scientists who explore these creatures.
Major coral bleaching on the Great Barrier Reef has now occurred two years in a row. Can the reefs recover?
What is coral bleaching? When ocean waters warm beyond normal ranges, corals eject the photosynthetic algae that live inside them. It’s these symbiotic algae that provide the corals essential nutrients. When the algae are gone, the corals are stressed and can easily die if the temperatures stay too high.
Coral bleaching started in the 1980s as periodic events in the tropical ocean. As global ocean temperatures increase due to global worming, bleaching events have become more frequent. Now, when El Nino causes temperature spikes the effects are devastating. There have been three worldwide mass bleaching events since 1998.
Since the new year started, we’ve been busy. Yes, we’ve been attending conferences, generating content and meeting with science teachers throughout the country. But, we’ve also been marching. A lot. Let’s see, it started with The Women’s March on January 21st, rolled into the March for Science on April 22nd and topped off with the People’s Climate March on April 29th.
Seems weird to be marching for science—but, OKAY. We ‘Woman-ed Up’, put on our ‘sensible shoes’, cooked-up clever phrases for homemade signs and gave up weekends. Why? Because if we don’t, the world may become an intolerable place for our children.

Every time we go to the National Conference for the National Science Teachers Association we become inspired and stoked about our work. It’s the one-on-one conversations we have with science teachers that brings us the greatest satisfaction.
One such conversation was with Barbara Shannon. Currently, Barbara is the Director of STEM Education for Synergy Academics whose mission is to create solutions that eliminate the achievement gap. But, before that, Barbara spent many years teaching science to kids in the Los Angeles Unified School District (LAUSD).
Dr. Micheli is a marine ecologist and conservation biologist. Fio, as she is known to students and colleagues, is Italian. Her career path wasn’t a straight line. At college in Florence she studied animal behavior, but after graduating, she took a job collecting intertidal animals for a nature documentary. Fio loved working in the rocky intertidal. This project launched her into marine science. She received her Ph.D. from the University of North Carolina and then went to the National Center for Ecological Analysis and Synthesis, in Santa Barbara, for a post doc. She never went back to live in Italy.

Horseshoe crabs come from an ancient line. Their ancestors appeared in the fossil record about 500 million years ago. And, while the horseshoe is a very auspicious symbol that is used to protect against any forms of evil, the horseshoe crab protects many of us from many diseases.
Over the millennia, this group has developed a trait unique to the horseshoe crabs alive today: their copper-based blue blood contains bacteria fighting compounds that cause the blood to clot when exposed to bacteria fragments.
RayTroll’s renditions of everything from salmon to marine mammals to creatures only found in the fossil record have become iconic in fishing, scientific, and environmental activism communities around the world. He seeks inspiration from extensive field work in marine science, paleontology, geology, ecology, and evolutionary biology. His paintings and mixed-media drawings are in the collections of the Miami Museum of Science, the Burke Museum of Natural History and Culture, Alaska Airlines, the Anchorage Museum, the Alaska State Museum, and the Ketchikan Museum.
