Immunity and the Art of War

 

READ THIS POST AS A REVIEW, AND THEN GO TO THE LESSON PAGE: IMMUNE SYSTEM 

What are the parts of the Immune System?

 -

 Who are the Bad Guys? (pathogens)

 

What is the body's first response to infection?

B-cells: what do they do?  When they are activated (by Helper T cells) they clone themselves into two kinds: first the plasma cell, which is a factory for antibodies, and also a memory cell (the diagram below should have antibodies on its membrane) which hang around a long time.





What do antibodies do?The antibodies, being released into the "humors" which are the bodily fluids or plasma, attach to the antigens, doing two things: first they prevent the virus from fusing with the cell membranes, and secondly, they flag the virus to be eaten by macrophages.




What is the Big Picture? Re-draw and memorize this.

But, of course, the main event is preparing for your presentations next Monday.  (Look over the assignment sheet from last week to see that you have included all you are required).  In addition, I would like you to turn in a bibliography, MLA style.  Easy way, use easybib.com --
Top of the page "The Free Automatic Bibliography and Citation Maker"   You should use the "Add Annotation" button to briefly describe what this resource was about.
If this is confusing, I will show you how to use this site next week, and you can turn it in the following Monday.

Sleep Cycles

 Sleeping...there's an app for that!  http://www.sleepcycle.com/
 Or this one:
http://www.proactivesleep.com/importance.php
This site has some actual information that you should read. On the header bar choose "About sleep" and click on each of the five sections.  Jot down a few notes. [Importance, Bodily cylces, Inertia, Napping, and Sleep problems.]

movie, quiz, activity pages- graphic organizer only, FYI.

MAIN THING: 
First, print out page 9 from this pdf :
http://science.education.nih.gov/supplements/nih3/sleep/guide/nih_sleep_masters.pdf
 It may be helpful or necessary to also print out pages 10-15 (these are included in the interactive, but it may be more helpful to some if they are printed out.)
Then go to the website, Lesson 2: Houston, We Have a Problem and complete the activity.  In the end you should have filled out the Astronaut Telemetry Evaluation Form (the page 9 which you printed out.)

 

Happy Thanksgiving!

Very little homework, and no homework page--that's something to be thankful for...
One thing only --Just start a sleep log.  Print out the first four pages of this pdf file: http://science.education.nih.gov/supplements/nih3/sleep/guide/nih_sleep_masters.pdf  and do what it says.  Get started right away, and if you forget one day, add another day to the end.  You will also need to count how many caffeinated drinks you have in the morning, afternoon and evening. 
Have a lovely holiday!

Follow the Yellow Brick Road...

True confessions--I am no teacher.  I am a home-school mom who is just one step ahead,  stumbling through the fields of knowledge, trying to find something better than knowledge, and leaving a path of breadcrumbs for you to follow.

Caffeine crystal

Hopefully, the homework will be that path.  Gather the information and make of it something more. Put together the pieces.  And may the water of facts and information become the wine of wisdom through the power of God's transforming grace.

Winner of the Ig Nobel Prize in Neuroscience goes to...

...Craig Bennett, Abigail Baird, Michael Miller, and George Wolford [USA], for demonstrating that brain researchers, by using complicated instruments and simple statistics, can see meaningful brain activity anywhere — even in a dead salmon.

Scanning Dead Salmon in an fMRI Machine Highlights Risk of Red Herrings 

Thank you for your kind attention...

Halfway to Christmas!!  I am enjoying the light and the warmth and beauty of these fine fall days.

I hope you are finding our study of the brain an interesting endeavor, and that your mind is expanding even as you practice discerning the difference between a supported scientific claim  and what is really only an opinion--and also telling the difference between a good and bad opinion.  I am fine with you having your own as you seek both wisdom and truth.

I would love to hear what your opinion is, especially as you look at some of the new studies on the teenage brain.  Agree/disagree??  There are six segments to the long video, and the first is really annoying, but don't give up, it should pick up.

Happy diligent studying.

Current Events:  10 years ago we finished mapping the human genome, now underway is an effort to map the neural connections of the brain.  It's called the Connectome.

1. The human connectome. Functional magnetic resonance imaging (fMRI) of the brain when it is at rest (sometimes called resting state fMRI) has emerged as a powerful approach for detecting correlations of large, infrequent fluctuations in activity levels across functionally related brain areas. A collaboration across 35 laboratories in 10 countries compared patterns of brain-function connection (called connectomes) in 1,414 volunteers, yielding harmonized brain maps based on age and gender.² As with the human genome, this functional connectome is important not only for providing a reference wiring map of the human brain, but also demonstrating intriguing, stable individual differences. New projects on the human connectome, supported via the NIH Blueprint for Neuroscience Research, will be exploring individual differences and developing more precise tools for measuring connections in the human brain. http://www.humanconnectome.org/consortia/
   

Technical Difficulties...AAARRRGHGHGH!!!

Sorry about the short class yesterday, and the lesson in frustration.  Oh, you didn't mind the short class??? then sorry about the long homework and  the lesson in perseverance. [insert maniacal laughter here.]   Homework will be posted as soon as I can figure out this mess...  My brain hurts.

Muscle Memory

This week finishes off our first section of A&P which covered a lot of vocabulary as well as the skeletal and muscular systems, from the microscopic view through the tissues, organs and organ systems.  For homework, we will complete our study of the motor unit/sarcomere, complete our posters of the muscle system and put some sense into all those words naming the muscles.  And we will review the vocabulary and diagrams that we have covered up till now.  I have added two more pages, besides the homework assignment, for ongoing review: Nomenclature review (which is vocabulary- think of naming things "nomen"  and "clad" in groups) --lots of Quizlets, actually.  Reviewing with Pictures is a compilation of the diagrams and illustrations that encapsulate our first 6 weeks.

And to start off, a lesson on learning.

Make Your Sarcomere Model At Home!

OK, so we will do for homework what I could not manage in class: our goal is to make a model of the sarcomere, that smallest of structural units that make up our muscles.  I will give you a list of videos you can watch and you can also find your own resources (just google it) and using what you can find around your house, make a model to bring into class, and be prepared to explain how it works--also known as "THE SLIDING FILAMENT THEORY"

just to get you going:http://www.youtube.com/watch?v=p1Z7IijeTDg&feature=related

There may be a few extra videos too.  But the main thing is...Model a Sarcomere!  (see homework page on side)

Dem Bones

I love this picture, but it needs a caption.  What should it be?  Please leave a comment.






.
Homework page is NOW COMPLETED.  Great class, I thought.  You guys are a delight to teach.

Just a note: it would be good to look over your notes shortly before class.  If you, like me, enthusiastically do all the homework on Tuesday, or even Friday, it is likely that you will have forgotten a lot by Monday.  Long-term learning requires that you go back over the materials several times over a period of days and weeks.  It really takes very little extra time when you get into the habit.

Tissues Lab

Some thoughts on class...  good job.  I never know what to expect... or how the lab will go... and so I sometimes have difficulty explaining what it is I hope to accomplish,   but you did good yesterday, I think, and I think we had a valuable time of learning.  That was the "Exploring" phase.
The homework reviews the information, and the first reading online gives you names and categories to put with your drawn  tissues and with the picture printout.  Take notes on this resource as if it were a lecture (and so you can review) and there will be a quiz for points at the beginning of next class.

The next unit is on the skeletal system.  Be ready for a lab by doing the skeletal section of the homework.

Anatomical Words

Thank you for today's class. I enjoyed each of your contributions and think that we will gain momentum as we go from week to week.  This week's homework is on the right. Click the "Week 2: Tissues and Systems" .  Call me if you have questions - 892-8540 or 827-4928 (that's our WOW! business phone.)

Psalm 139

Parents & Students,

Starting Monday, we will be studying anatomy & physiology for science, from 1:45-3:45.  This is a change from the schedule previously given.  There will be only one class per week, so that is different from last year.  But not to worry, there will still be homework.  And, I have ordered the Brains.  Literally.

I am very excited about teaching this year and learning along with you.  I have a new blog: http://wonderfullymade12.blogspot.com/ which will be your homework guide.  The textbook is online.

KEEP READING. I would like the moms to join us for the first day of class so they can understand the new homework system, which will be like a video game where you earn levels (and hopefully rewards!).  And it will be like an all-you-can-eat buffet, where you can choose from a lot of options, but you don't have to "eat" it all.

If you know other HS students not part of JB, they are welcome to join our group.  The once-a-week class-time might be convenient for them.

Art will be on Thursdays from 10:45-12:00. We will be working this semester on ceramics.

I would like to collect a materials fee of $35 per student for art, and $35 for science.  (no book needed, but expect to print out quite a few pages.)

I have been and will be working very hard to make this class interesting & memorable.  It is an important subject; I find it strange that the study of our bodies and our health would take such a small  and optional place in our state educational requirements. Those of you who are mainly looking to fulfill graduation requirements (and therefore are enrolled in NOVA or North Bay)  may wish to take the class without the homework portion; I think you would still get a lot out of it.  (This is a one semester class, tentatively.)

Feel free to call with any questions.  Also let me know if you will be there Monday.  In fact, hit "reply" just so I know you read the email. 
Thanks, Veronique
