Week 27 - Notes and reading for Thursday / Friday -

 Week 27b – 03.25 / 03.26 – Thursday / Friday – 2021


  1. I. Current Events:  Weather and Space Junk / Rainforest! (CNN10)
    1. a.Australia has been trying to recover from devastating fires and now is dealing with floods. (It’s their Autumn right now!)
    2. b.Newton’s Second Law: Force = Mass x Acceleration – A small object going very fast has tremendous force!
      1. i.(For Friday) Rainforests have been burned to make room for livestock grazing.
      2. ii.The RESPIRATORY and CIRCULATORY systems … 
    3. c.OUR atmosphere is about 20 percent oxygen … thanks to PHOTOSYNTHESIS.
    4. d.RESPIRATION and PHOTOSYNTHESIS are opposite reactions.
      1. i.Write the reactions here: _______________________
      2. ii.Muscles, breathing, and our ATMOSPHERE:  The human body systems work together.
    5. e.A MUSCLE called the DIAPHRAGM (“Belly breathing”) is located below the lungs. When it CONTRACTS the lungs expand because air is forced in. 
      1. i.Note: CONTRACTS: That’s all muscles can do! Muscles DO NOT push, they ONLY contract!
    6. f.WHY is air “forced” in?  (Straw demonstration.)
    7. g.WHY are we bothering to breath in the first place? (Sounds silly at first. BUT … What’s going on?)
    8. h.The LUNGS (Part of the RESPIRATORY system) exchange the Carbon Dioxide that was in the blood with Oxygen in our atmosphere.
    9. i.Remember our heart rate experiment? (What was YOUR heart rate? ________ BPM). 
    10. j.This exchange wouldn’t happen without the HEART (Part of the CIRCULATORY SYSTEM) moving our BLOOD (Created by the SKELETAL system) through VEINS and ARTERIES.
      1. i.(HW) What’s the difference between veins and arteries?
      2. ii.BILL NYE: Atmosphere:  We live at the bottom of an ocean of air!

Week 27 Reading

03.26.2021


     Middle School science covers a broad range of topics. Sometimes it’s helpful to work backwards from the concepts we want to understand to where we began. That’s often what we do as we approach the last weeks of school for the semester; see where we’ve been and where we’re going.

   Our goal is to have a good foundation for understanding life.  That’s a big, complicated subject and we wanted to give some background on how we know what we know (the Scientific Method) and the conditions that make life possible (Earth Science)

     The story brought us all the way back to the Big Bang – the time when our universe began.  A bit if understanding about light helped us know that our universe probably is about 14 billion years old.  

     Knowing about the four fundamental (basic) forces of nature helped us get a clearer picture of how “simple” atoms like Hydrogen can combine – through fusion in stars – to make all the heavier elements necessary for life.

    By the time our solar system, and Earth, formed – about 4.6 billion years ago, all the elements needed for life were available. Those elements are like the building blocks and cells - the basic units of life - put together and rearrange those building blocks in endlessly complex ways.

      When the elements are rearranged, it’s called a chemical reaction, and none is more important than photosynthesis for setting the stage for complex animals.

     It took billions of years for the oxygen released into Earth’s atmosphere to build up enough for life to take advantage of this for releasing energy from chemical bonds.

     As life evolved from one-celled organisms it diversified into several kingdoms. (Plants, Animals, Protists, Fungi, and Bacteria.) Our branch of this evolutionary tree, the animals, breath the oxygen in our atmosphere and humans are capable of affecting every other branch on the tree of life, which is why we incorporate ecology into our studies.

     We spend time learning about our species in detail and try to get a picture of how our eleven body systems work together, and work with our environment, to sustain life.  While we study systems and species individually, it’s always with an eye towards the connections between subjects, species, the non-living systems of our planet, and the living system – of which we are a part.

Week 27 Rover Assignment

 

Week 27 – Rover Assignment – 

Options:

     Turn in either a drawing of, or a picture of, your “Egg drop” experiment from earlier in the week. OR turn in a picture of your budget for your Egg Drop. OR, if you did not have the packet and you were unable to do the experiment; answer the following questions and turn them in via email. 


  1. 1. Why are we looking for signs of life on Mars? In other words, what’s so special about Mars that it may have once (or may still) have life?

Week 25b - Notes and link to video

March 11 / 12 – Week 25b – Science – 


The CAPITALIZED TERMS are our KEY TERMS for week 26.

Remember: Test 24 and 25 are, currently, “live.” Please be sure to take the tests before 03.13.2021 – Saturday at 9:00 pm. All of the material covered in the on-line assessments is in our text and notes.



  1. I. The tallest person ever was almost nine feet tall. The reason he became so tall was due to his ENDOCRINE system, a series of GLANDS that use HORMONES (chemical messengers – often proteins - ) to signal cells to do certain things. In the case of a nine-foot person; his PITUITARY gland never sent a chemical signal to stop growing.
  2. II. The glands and HORMONES regulate:
    1. a. Growth and development.
    2. b. Reproduction
    3. c. METABOLISM
    4. d. Responses to STRESS.
    5. III. GLANDS of the ENDOCRINE system:
    6. a. Hypothalamus:  Controls the Pituitary
    7. b. Pituitary:  Growth
    8. c. Thyroid:  METABOLISM
    9. d. Parathyroid:  Regulates calcium in the blood
    10. e. Adrenal: “Fight or flight” response.
    11. f. Pancreas:  Regulates blood sugar.
    12. g. Pineal:  Melatonin. (Sleep / wake cycles)
    13. h. Ovaries / Testes: Female / Male sex hormones and cells
    14. IV. Strange Days on Planet Earth:  Follow the link to the first 15 minutes of this episode of Strange Days … https://www.youtube.com/watch?v=eVKlt3DLzso
    15. V. This episode – in the first fifteen minutes, brings together much of what we’ve done since September in this class. The most important highlights include:
    16. a. We’ve studies water as a universal solvent.  UC Berkeley biologist Tyrone B. Hayes follows the trail of a weed killing chemical that is widely used in the United States. The name of the weed killer is Atrazine and it has been implicated in damage to the ENDOCRINE system of frogs.
    17. b. Frogs are AMPHIBIANS: They live in, and depend on, water for part of their life cycle.
    18. c. Humans are exposed to ENDOCRINE disruptors through plastics on a daily basis. It’s nearly impossible, in modern life, to go through a day without using plastic. However, many chemicals in plastics may be hurting our ENDOCRINE system.
    19. VI. Addition Key Terms for week 26
    20. a. BRAIN
    21. b. SPINAL CORD
    22. c. NERVE CELL
    23. d. AXON
    24. e. DENDRITE
    25. f. CENTRAL NERVOUS SYSTEM
    26. g. PERIPHERAL NERVOUS SYSTEM

Week 25a notes

 



WEEK 25 NOTE

 Note home: 03.10.2021


Week 24 and Week 25 tests.


Hi Scientists:

Below is the link to this week’s test. (WEEK 25) – ALSO, below, is the link for last week’s test. BOTH tests are now “live” and will be available to take through 03.13.2021 – Saturday.


     We are in week 25 and we know that there is an on-line assessment every week. I had quite a few emails asking for last week’s test to be re-opened as it was not taken for various reasons.  We have a WEEKLY test and it’s the responsibility of the student to take them. If it is missed, it is a zero in the gradebook. This far into the year we know what is expected and as we do not have as many assignments (due to distance learning) the students are expected to complete the on-line assessment and one other assignment each week. I’m aware that distance learning is quite challenging. However, ALL of the material in your on-line assessments are in our text and our notes. Please refer to the blog and your Google Classroom to obtain any missing notes. Also, take the time to review the YouTube videos.


Thanks


Scott Forbes

Week #22 Notes - Part II -

 Hi Scientists;

Here's some screen shots from the notes (02.11 / 02.12). The YouTube video link was sent and is live. Our week 22 quiz is due by the end of today. The eleven (11) Human Body Systems are our Key Terms for Week #23 (after break.) Finally, there's an optional, extra-credit assignment due no later than February 21st - (Page 143 from the text, questions one through eight - simply send a picture of your work like we do with the Key Terms each week.)

The notes and video are designed to go along with Dr. Guccione's lessons.  Have a wonderful week and see you on the 22nd and 23rd. :-)

Scott Forbes

PS ... including a pic of the wildlife that's watching over your field here at IBL until we're back from social distancing. Canadian Geese. They only have to worry about the coyote that's been visiting and the occasional errant golf ball shot from a science teacher on break :-)

 Hi Scientists;

Here's the link to this week's test. The access code is 5277G5

https://www.classroomclipboard.com/854670/Test/A40B8DA2-64DA-4034-9D4E-68442A4578ED

There is no vocabulary due this week, as we had Monday and Tuesday with Dr. Guccione and an excellent example of how disease spreads. Our next lecture and notes will focus on vaccinations. The test is due by the end of the day on Friday and please use both your text book and our interactive student notes.

Happy Tuesday!
