Science Fair Wrap-Up and Learning to Solve a Water Issue

Part 1
First, we checked our  Science Fair Templates to see our final grades form the Science Fair that occurred Thursday, February 27th. We also cleaned up anything that was left from the Science Fair.





Part 2
What we want to know about the Pacific Trash Vortex and Fishing by Compressor Diving:


We watched a part of  a video and answered the questions on this link on our taskbooks. 

This is the scuba diving outfit:




Sometimes during the video Mr. Pro would stop and explain 
something important to help us answer our questions.

video


After watching the video, these were the answers we got:

1) Why is it a problem?
  1. Too few fish - we have fished so much that there are far fewer fish.  
  2. So fisherman have to use different techniques such as compressor diving.  Compressor diving is extremely dangerous.  
Explain the cause of the problem and science related to the problem.
  1. The area is overfished
The fish don’t have time to reproduce.  Have to understand science of reproduction.  
  1. They don’t have the money to afford safe diving equipment.   Understand the science of pressure and decompression sickness

Explain what people are doing to solve the problem.
  1. Nothing, they are going deeper to find more fish.  
    1. They could use nets that allow smaller fish to escape.  
  2. Not much

Explain how nature acts to solve the problem (challenge).
  1. Nature constantly reproduces and balances change to ecosystems.  But it’s difficult for the coral reef to keep producing fish if every time it’s fished 50% of the fish are taken.  
  2. ---

Explain & discuss other ways to solve the problem in the future.  
  • Have restrictions on times to fish.  
  • Have parks where no fishing is allowed.  
  • Have laws that limit the amount of fish/seafood you can take.  
    • Have the infrastructure and officers to enforce restrictions and laws.
    • Fish hatcheries to help grow small fish and then release them.  
    • Fish farms
Donate equipment to the fishermen.
Educate the fishermen.  
Government or NGOs could help them find other jobs.  


After we were done, we watched the second video on the document and answered the same questions

  1. Why is it a problem?
The immediate problems are:
    • birds are eating the plastic and it’s bad for the birds’ health
    • plastic blocks the sunlights so  plankton, plants and algae (the producers) won’t grow as much and there won’t be as many.  If there are less plankton, there will be less species, including fish, sharks, and pretty much all species, will decrease in numbers.
    • plastic/garbage is covering beaches so species have difficulty moving around, plastic can get caught on animals
    • It’s really ugly!   
    • we are still producing millions of tons of plastic all the time because we can’t get rid of it after we use it.  It stays around for millions of years unless we
      • recycle it OR
      • burn it

  1. Explain the cause of the problem and science related to the problem.
    • Water cycle: explain how the garbage gets to the middle of the Pacific Ocean from the land (for example, from BSD City)
    • Food chain: explain the ocean food chain starting with phytoplankton.  If there’s less sunlight, there’s less phytoplankton, there’s less consumers and less living things overall.

  1. Explain what people are doing to solve the problem.
    • How do we clean it up?
helicopter connected to a big net that scoops out the garbage
A big boat with some kind filter system that catches the plastic.  The plastic can then be taken to land where it could be recycled or dried and burned to generate electricity.  
Use a huge net to collect all the garbage.  

  1. Explain how nature acts to solve the problem (challenge).

  1. State science related to the solution.  
    • What are other alternatives to using plastic?
Chemistry and development of better plastics.
Other materials, especially ones made of plants.  
    • How can we avoid letting garbage get into ocean water?
Put trash in trash bins.  
Recycle plastics.
If you are in remote locations - like the village we went to - take out your plastic as well.
    • How can we decrease how much plastic we use?  
Use a different material.  Instead of using plastic bags every time you go to the stores, use a reusable bag, like a canvas bag or your backpack, to carry things.
Take care of your plastic belongings and use them as long as possible.  



Later, we had to read the article and choose the six most important words of the article and write a summary of what they read using those words. 

  • Choose 6 keywords from the last section of the article called “Patching up the Patch”.
  • Use those 6 words to make a 2-4 sentence summary of the section.

  1. Juliana, your post was very well organized, and I liked how you separated it in parts. Nice job also be answering the questions in the end, but I think you should not give people the answers, just a brief idea. Also, you missed question number four. Don't forget to fill all the areas, if you are going to actually fill it in. I also liked how you put videos in your post, that was innovative and it also helps people to see and interoperate how the class was, and get a brief idea to remember. Putting the links to articles is also a very good idea, but make sure your post has the right labels. You are missing the label Scribe Post, be careful. Other than that you post was good and I think that it covered well the class we had on that day. Great Post!
