This week we will be looking at the brilliance of bioluminescence and discussing and researching one of the famed musketeers of the sea; influential inventor Jacques Cousteau. Did you know that at least 1,500 species of fish are known to be bioluminescent, including sharks and dragonfish—and scientists regularly discover new ones. Among the most iconic are deep-sea fishes like the anglerfish, whose females sport a lure of glowing flesh that acts as bait for any prey close enough to be snatched which was portrayed in the movie Finding Nemo!
Today we will be looking at what bioluminescence is and creatures that use this skill to survive the depths of the ocean including the Twilight Zone. Bioluminescent organisms produce and radiate light. There are thousands of bioluminescent animals, including species of fishes, squid, shrimps and jellyfish. The light these creatures emit is created inside their bodies, meaning they are able to glow and glitter in complete darkness. Some of the planet's bioluminescent animals live in the deep ocean (although not all of them). Many exist in the twilight zone, the part of the ocean from 500 to 1,000 metres deep, which is always dark in its lower margin. In this environment, the light some animals can create for themselves is fundamental to survival. It is thought that up to 90% of life in the twilight zone creates light in some form. Using the documents and links below we would like you to look into which animals have this skill and look at the sheer variety of creatures who use this in the Twilight Zone.
Carrying on from yesterday we would like you to watch this amazing documentary ( link below) on the creatures that use bioluminescence and the exciting information people have found out about these fascinating creatures. Then using all your new learning we would like you to design your own bioluminescent creature! Remember marine creatures rely on bioluminescence for communication, finding prey, camouflage, and more so think about these features when creating your own.
Today we would like you to begin researching and learning about a famous undersea explorer called Jacques Cousteau. Jacques Cousteau was a French undersea explorer, researcher, photographer and documentary host who invented diving and scuba devices, including the Aqua-Lung. Undersea explorer Jacques Cousteau co-invented the Aqua-Lung, a breathing device for scuba-diving, in 1943. In 1945, he started the French Navy's undersea research group. In 1951, he began going on yearly trips to explore the ocean on the Calypso. Cousteau recorded his trips on the TV series The Undersea World of Jacques Cousteau. Below you will find a link to a power point and websites to help you begin your research.
Continuing from yesterday, today we will be looking at the documentaries and films Jacques Cousteau made to support and highlight oceanic protection. In 1966, Cousteau launched his first hour-long television special, “The World of Jacques-Yves Cousteau." In 1968, he produced the television series The Undersea World of Jacques Cousteau, which ran for nine seasons. Millions of people followed Cousteau and his crew traversing the globe presenting intimate exposés of marine life and habitat. It was during this time that Cousteau began to realize how human activity was destroying the oceans. He also wrote several books, including The Shark in 1970, Dolphins in 1975, and Jacques Cousteau: The Ocean World in 1985. With his increased celebrity and the support of many, Cousteau founded the Cousteau Society in 1973, in an effort to raise awareness of the ecosystems of the underwater world. The organization quickly grew and soon boasted 300,000 members worldwide. In the 1980s, Cousteau continued to produce television specials, but these had a more environmental message and a plea for stronger protection of oceanic wildlife habitat.
Using all your new learning this week we would like you to create a powerpoint on Jacques Cousteau. We would like it to include:
Extra challenge: Try and add a video in to your power point
If you are unable to create a power point, you could create an information leaflet or a 3D timeline using paper and resources you have at home.
