Planet or Plastic?

posted Sep 17, 2018, 1:09 PM by Jerrid Johansen

I don't even know where to begin with this topic?  The numbers are staggering.  The pictures are disturbing.  And all of it makes me upset.

Spend some time exploring the National Geographic Series, PLANET OR PLASTICStudy the pictures.  Read the captions.  Check out the infographics and data tables.  Watch the short videos.  Get a sense of the magnitude of the problem.

Some things to consider:
  • What is plastic, and what's its history?
  • What are the quantities being described in these links?
  • How much is produced?  Recycled? 
  • How much ends up in landfills?  How much ends up in our waterways?
  • What are the problems associated with plastic pollution?
  • What are the challenges in dealing with plastic pollution?
  • Who is responsible for dealing with this problem?
  • What are the solutions?

Food Webs and Current Events!

Take a moment to read this article on Genetically Modified Mosquitoes being released in Africa, then address the following questions with your partner:

  1. Why are researchers releasing Genetically Modified Mosquitoes into these African Countries?
  2. What impact, if any, with the decline in mosquito population have on the local food web/ecosystem?
  3. How do you think the environment respond to a decline in mosquito population?
  4. Is it worth risking the health of the ecosystem/food web to possibly reduce the chance of humans in the area getting malaria?  Why or why not?

Conserving Biodiversity

posted Aug 30, 2018, 5:12 PM by Jerrid Johansen

By now you should be on board that biodiversity is a valuable natural resource that has countless environmental and social benefits.  So now the question becomes, "What do we do to protect and conserve biodiversity?"

  • Do a simple google search of Conserving Biodiversity, and check out 3-5 of the sites.  
  • On a piece of paper, identify at least 8 things that can be done on a global scale to conserve biodiversity.  
  • Also identify at least 8 things that you and I can do at a local level to conserve Biodiversity.

  • Pretend that you have $100 million to donate to various conservation efforts around the globe.
  • Research different conservation efforts and determine which ones would be worthy causes to support.
  • Questions to consider:
    • What do you find valuable, and want to protect?
    • Are the local or global?
    • Are they targeting one species, or multiple?
    • Are they conserving a whole ecosystem, or a specific area?
  • You must select at least 3 organizations that you would support, and briefly explain why you would choose to support them.

  • Research and identify at least 3 conservation efforts that exist in our part of the world (Nebraska, Iowa, Kansas, Missouri).
  • Who are they?  What is their mission?  What do they do?
The end.
Whatever you don't get done, please complete over the weekend.  
Have a great weekend!

Work with a partner to complete the following activities for class on Thursday, August 30th

1.  Watch the TEDEd video on Biodiversity

2.  Answer the following questions about the video:
  • What can cause a species of organisms to become less diverse?
  • Humans have cut and frayed the woven tapestry of Earth's biodiversity.  Describe three ways.
  • Correctly use the following words in a well-constructed paragraph.  Be sure to describe the differences between each of them and how they are intertwined:  Species diversity, biological diversity, ecosystem diversity, and genetic diversity.
  • From both the verbal and visual descriptions provided in this lesson, sketch your own diagram of the Amazaon Rainforest Food Web
3.  Read the article from Nat Geo about "LIFE IN A CUBIC FOOT."  Take the time to enjoy the photo galleries!! They are beautiful!!

4.  Watch at least TWO OF THE VIDEOS about the Life in a Cubic Foot project.  

5.  Answer the following questions to summarize the day:
  • How would you describe the concept of Biodiversity?
  • Why should we value and protect Biodiversity? 
  • Compare and contrast your "Cubic Foot" experience with those from Nat Geo.  What would you need to properly study life in a cubic foot?  If you properly studied a cubic foot in Walnut Creek, how many different organisms do you think you would find?  Explain.
The End!

    There are three slides with material you need to complete.

    The Water Cycle.pptx

    If you finish, i would encourage you to start answering test questions 1 and 2 on your white, Unit 12 sheet.  That will be assigned by the end of this week, and will be due early next week.
