Marine Research/STEM Grade 7

  
          The theme for the Marine Research/STEM program in Grade Seven (7) focuses on global climate change, pollution and the impact of fossil fuel consumption on the environment.  Students will use the information they acquired in Grade 6 to develop a better understanding of how technology and waste is creating environmental challenges for future generations.

     Below you will find an assortment of featured articles, videos and activities that complement the Marine Research/Design Program for Grade 7.  Follow the links to learn more.

 An Inconvenient Truth (DVD)
     An Inconvenient Truth makes the compelling case that global warming is real, man-made, and its effects will be cataclysmic if we don’t act now. Gore presents a wide array of facts and information in a thoughtful and compelling way: often humorous, frequently emotional, always fascinating. In the end, An Inconvenient Truth accomplishes what all great films should: it leaves the viewer shaken, involved and inspired.

 The Day After Tomorrow (DVD)
     Global Climate Change is a reality and its impact on the overall health and future of mankind is vividly portrayed in this science fiction thriller- The Day After Tomorrow.  Three fundamental concepts are illustrated during this two hour movie.  They are the Greenhouse Effect, Global Climate Change and the World Ocean Conveyor Belt.  This movie provides one of the best explanations as to how the world ocean conveyor belt helps to stabilize global climate conditions and what can happen when ocean currents stop or are redirected.  Students may find it difficult to take notes during this visual smorgasborg but there is a lot of science to be experienced nonetheless.

 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.

 A Plastic Ocean (NETFLIX)
     In the center of the Pacific Ocean gyre our researchers found more plastic than plankton. A Plastic Ocean documents the newest science, proving how plastics, once they enter the oceans, break up into small particulates that enter the food chain where they attract toxins like a magnet. These toxins are stored in seafood’s fatty tissues, and are eventually consumed by us.  If it was happening in one gyre, they suspected it was happening in all of them. But the filmmakers needed experts to prove it.

     This movie was released in 2016 and it tells a very frightening depiction of how our fascination with disposable plastic is literally poisoning our oceans and its food chain.  This is a video that you cannot ignore.

 Pipe Cleaner Tower Lab
     This lab activity introduces students to the design process by working in groups to design and construct a freestanding tower using just their own creativity and some simple materials.  Every day, scientists and engineers working with many different types of materials must design an object or structure within a limited amount of time.  They often encounter unforeseen challenges or obstacles that can slow down progress of stop the project all together.  Material costs, limited time and changing demands by the customer can seriously influence the success or failure of the project.

  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.

 China's Toxic River (60 Minutes) 13 min.
     Our society is based on the idea that "newer is better" and "out with the old" when it comes to smart phones, digital video and computer hardware.  We are always upgrading to something newer and better.  But what happens to the computer monitor, VCR or mother board that gets thrown in the recycle bin?  Watch this video special from 60 Minutes and discover that our thirst for technology is creating some very toxic and potentially deadly problems.

 Creature Feature: The Lionfish
     It took as few as three lionfish to start the invasion. Or at least, that's the best guess. No one knows how the fish arrived. They might have escaped into Florida's waters in 1992, when Hurricane Andrew capsized many transport boats. Or they might have been imported as an aquarium curiosity and later released.
But soon those lionfish began to breed a dynasty. They laid millions of gelatinous eggs that released microscopic lionfish larvae  and the rest is history.   The fish, unknown in the Americas 30 years ago, settled on reefs, wrecks and ledges. And that's when scientists, divers and fishermen began to notice.

 Super bugs! Antibiotic resistant bacteria (60 Minutes) 13.17 min
     Antibiotic bacteria calls over 23,000 people in the United States each year and these numbers are going up.  The United Nations estimates that by the year 2050 more people will be killed by antibiotic resistant bacteria than almost all forms of cancer combined.  But how is this happening?  Antibiotics are often found in some of the foods that we eat each day.  Our bodies immune system becomes weak over time and is unable to fight even the most non lethal forms of infection.  This situation can only get worse.

     This is the first part of a two part assessment that covers human health and how acceptable medical practices of the last decade could spell doom for mankind in the not too distance future.

 Nature's Superbug Killers! Virus that kill antibiotic resistant bacteria
     Usually when we hear the word "virus" we think of nasty pathogens that can make us sick.  However, medical research has discovered a unique way of combatting the growing number of antibiotic resistant bacteria by using a virus.  This assessment introduces students to the nature of the virus and its unique way of invading its host.  Using what they learn about viral reproduction student's will gain a better understanding on how scientists are using this characteristic to help us in the fact against deadly bacterial infections.

 Silent Invaders: Zebra Mussels (YouTube) 21.30 min
      The Zebra Mussel, Dreissena polymorpha is a small, striped bivalve about the size of dime that is native to Russian oceans such as the Caspian, Black, Aral and Azov seas.  The Zebra mussel was first observed in North America in 1988 in Lake St. Clair (a body of water that is on the border between Michigan, USA and Ontario, Canada). They quickly infested the Great Lakes and used the Mississippi waterway to travel across the country. They are more than just a nuisance and represent a potentially devastating impact on native species, local economies and human health.  Here's how.

 Invasive Species: Cane Toads!  (YouTube) 7:58 min
      Anyone living in south Florida is familiar with the cane toad (Bufo marinus).  There is nothing pretty about these creatures when they invade your backyard, wander into the garage or start feeding from the family dog dish.  They are voracious eaters and grow as large as a melon with a very nasty, potentially lethal defensive mechanism.  They are not indigenous to the United States but were introduced by well intentioned scientists who were trying to quell the mosquito population.  Needless to say, it didn't work as planned.

 Invasive Species: The Amazing Story of the Kudzu Vine!  (YouTube) 27.35 min
      Anyone living in the South is probably very familiar with Kudzu.  This invasive vine has been described as both a blessing and curse.  It was introduced into the United States during the turn of the 19th century and quickly spread across much of the south and portions of the southern mid western states.  It grow very rapidly and is tough to kill being able to lie dormant for up to ten years before resuming its conquest.  However, man has found some uses for this invasive plant that might change our opinion of this nuisance.       Learn more about this invasive species and what can be done to control the invasion.
