 Jellyfish Attack Japan (YouTube.com)
      The title of this segment seems like it was taken from a bad science fiction film but believe it or not its true.  The nomura jellyfish is invading the fertile fishing grounds off the coast of Japan causing widespread panic and damage to one of Japan's most important sources of seafood.  These large creatures have no central nervous system and are capable of producing a billion eggs at a time causing massive "blooms" of baby jellyfish.  But what is causing this phenomenon and is there anything that man can do to stop this invasion?  Watch the videos and learn more.

 The Greenhouse and Global Climate Change (YouTube.com)
      If you were to interview a small crowd of people at the local mall and ask them to explain the Greenhouse Effect or define Global Climate Change, most people would be unable to do so.  Many of us are familiar with these terms but really dont have a fundamental understanding of what they mean, their causes and how these phenomenon affect our daily lives.  In addition, many people have grown so used to hearing about GCC that they have become insensitive to the reality that it is here to stay and is having a terrible impact on the environment and ultimately our quality of life.

 The Chambered Nautilus (YouTube.com)
       The chambered nautilus (Nautilus pompilius) is a large, mobile cephalopod which is called a "living fossil" and has been the subject of poetry, artwork, math, and jewelry. They have even inspired the names of submarines and exercise equipment. These animals have been around for about 500 million years—even before the dinosaurs.  These mysterious creatures occupy some of the deeper parts of the ocean and there is not a great deal of information about them.  They are evolutionary marvels and they can provide us with clues as to how life evolved in the Devonian Ocean.

 The Business of Trash (MSN.com)
      Every year, countries from all over the globe produce millions of tons of trash in a variety of shapes and sizes.  Recycling man's garbage should be a popular and potentially profitable enterprise but is it?  Finding a suitable resting place for some of this waste is challenging and very risky given the fact that our household garbage may contain chemicals and contaminents that are harmful to the environment and dangerous to our health.  In this topic, we are looking at the handling of garbage from a different prospective- can a business make money processing garbage?  Read on and find out.

 Prehistoric Sharks! (Paleoworld)
      Long before dinosaurs walked the Earth, sharks were roaming the oceans. Their legacy has been traced back at least 420 million years which is quite amazing. They have been able to evolve as needed in order to survive.  Scientists think that the most dramatic evolution of sharks took place during the Cretaceous period. During this time there was an abundance of food, sharks grow, and different species appeared.  But studfying prehistoric sharks is challenging because their skeletons are made of cartilage which does not fossilize very easily.  This 30 minutes segment of Paleoworld takes us back about 350 million years to begin our journey through the evolution of sharks.

 How the Universe Works:The Big Bang Theory (YouTube) (46 min)
      Approximately 4.6 billion years ago, our planet Earth was formed through a series of violent collisions, explosive releases of thermal energy and a prolonged period of cooling and precipitation. The first atmosphere was toxic and consisted of sulfuric acid, ammonia, water vapor and other greenhouse gases.  Life would not emerge onto dry land for several billion years.  But how did this remarkable event occur in the first place?  Was there a single atom or particle of matter from which the entire universe as we know it emerged?  Eventually, the Big Bang Theory was born.

 Why Don't All Skeletons Become Fossils?  (YouTube- 4.33 min))
      Most people believe that the fossilized skeletons living inside museums and universities are the actual bones of the once living dinosaur, mammal or reptile.  This could not be further from the truth.  Only about 1% of all skeletons eventually become fossils and finding those that have been lucky enough to go through this process is very difficult.  This video provides us with a glimpse on how skeletons become fossils and does a great job of describing many of the challenges that prevent many of the ancient dinosaurs from becoming a permanent display in the Museum of Natural History.

 Building A Dinosaur from a Chicken  (TED Talks- 18.33 min))
      Renowned paleontologist Jack Horner has spent his career trying to reconstruct a dinosaur. He's found fossils with extraordinarily well-preserved blood vessels and soft tissues, but never intact DNA. So, in a new approach, he's taking living descendants of the dinosaur (chickens) and genetically engineering them to reactivate ancestral traits — including teeth, tails, and even hands — to make a "Chickenosaurus".

 How to find dinosaur fossils?  (TED Talks- 15.49 min))
      What happens when you discover a dinosaur? Paleontologist Kenneth Lacovara details his unearthing of Dreadnoughtus — a 77-million-year-old sauropod that was as tall as a house and as heavy as a jumbo jet — and considers how amazingly improbable it is that a tiny mammal living in the cracks of the dinosaur world could evolve into a sentient being capable of understanding these magnificent creatures. Join him in a celebration of the Earth's geological history and contemplate our place in deep time.

 The Cambrian Period  (National Geographic- 15.49 min))
      What 550 million years ago, an explosion of life took place on planet Earth.  During this time, some 10,000 new species emerged from the primodial ocean for no apparent reason.  Every known body plan was represented and many of the creatures are unlike anything seen on Earth ever since.  Evolution was in full swing accelerated by the emergance of the first Predator- Anomalocaris.  This relatively short video by National Geographic gives students a tantalizing taste into a part of history that is seldom mentioned in textbooks or the classroom.

 Plate Tectonics and other Great Discoveries in Earth Science- Bill Nye  ( 46 min)
      Have you ever wondered what the surface of the Earth looked like 250 million years ago?  Have you ever thought that it was strange that fossils of the same prehistoric creature can be found on the African AND South American continents and yet they are separated by an ocean?  Consider this, the center of the Earth's core is hotter than the surface of the Sun and the forces deep below our feet can literally move mountains.  We will examine some of these forces in this lesson module starting with a Brain Pop video followed by our good friend, Bill Nye.
