Welcome to Mrs. Wilson’s Class Website!

Hello students and parents!  Welcome to a new school year!

This space is reserved for General Announcements that pertain to my classes.  Specific things you need to know can be found by clicking on the links to the class in which you are enrolled this year.  I am looking forward to working with you this year, as we explore all the ways in which God has designed the world, including our amazing bodies.

A Heart Surgeon Speaks Out

Despite decades of telling people that eating a low fat diet and substituting polyunsaturated oils (such as corn or safflower oil) for saturated fats (like butter) so that their risk of heart disease will be less, doctors have seen a rise in heart disease instead of a drop.  “Statistics from the American Heart Association show that 75 million Americans currently suffer from heart disease, 20 million have diabetes and 57 million have pre-diabetes. These disorders are affecting younger and younger people in greater numbers every year. ” (see article link)

Dr. Dwight Lundell has left his surgery practice to focus on nutrition treatment for heart disease based on  “The discovery a few years ago that inflammation in the artery wall is the real cause of heart disease is slowly leading to a paradigm shift in how heart disease and other chronic ailments will be treated.”  The inflammation is actually being caused by the low fat diet that we have been encouraged to embrace over the last 50 years.

This very interesting (and easily understood) article can be found here.  Food for thought.

 

Learning Styles – What’s Yours?

For years now, first as a mom homeschooling my own kids and now as a classroom teacher, I have been told that if I really want our kids to learn well, I/we should teach to their particular learning style.  It was fun to go through some of the workshops and figure out what each of our own styles were by taking various surveys like this   or this .  Although I think it is  a great idea to teach a topic in a number of different formats to get the message across, I have often wondered how successful the efforts have been for individual students.

In preparing to teach a unit on the brain in my anatomy classes, I ran across an article that addressed this issue of learning styles.  The article intrigued me because the author suggested that learning styles was not much more than a myth.  A MYTH! That got my attention.  The author is a neuroscientist who has written a book about myths about the brain.  Here is the link in wired science to this article.  I hope you enjoy the read!

Don’t blame the turkey!

Have you been blaming the TURKEY for making you sooooo sleepy after eating every Thanksgiving?   It is true that there is a sleep inducing chemical in turkey, but there is actually no more (tryptophan) in turkey than any other meat (or tofu for that matter!).  So what’s the deal?  Why do we all fall into a heap on the couch and miss half the game because we can’t keep our eyes open?

The answer is CARBS, not turkey.  Look at the rest of table… mashed potatoes, stuffing, marshmellow-topped sugary yams, pumpkin pie,… the list goes on.  When you put all those carbs in your body, insulin is released to manage the sugar high you just imposed.  When that happens, the amino acids that were blocking the tryptophan from getting to your brain are off fighting the sugar battle, allowing tryptophan to get into your brain and get turned into seratonin.  Presto! you get mellowed out and fade away to dreamland.

So do yourself a favor.  Load up on turkey and go light on the carbs.  Better yet, get the family out for a walk afterwards, instead of sitting in front of the screen.  Your body will thank you.

HAPPY THANKSGIVING EVERYONE!  We have so much to be thankful for.

PS – Here’s the link to the article in Wired Science where I got my info.

Climate Change – Is it Really Happening?

In light of President Obama’s current trip to Asia and the agreement that he and China’s president have made on carbon emissions (read about it here), puts the global warming (AKA Climate Change) debate in the spotlight once more.

I thought you might find it interesting to read what one of the co-founders of the Weather Channel, John Coleman, wrote recently about the science behind the claims that the earth is warming. “I have studied this topic seriously for years. It has become a political and environment agenda item, but the science is not valid.”  Read the rest of the article here.

Bacteria: Good or Bad?

When you hear about bacteria, isn’t your first reaction to think “Yuck!  Bacteria bad, anti-bacterials good!”

Well, one of the newest fields in biological research today (only 10 years old) is focused on the importance of good bacteria that we are exposed to throughout our lives.  Recent research has shown that the more we try to avoid bacteria, the worse off we are in regards to our immune systems.  It turns out that the more bacteria we are exposed to early childhood, the stronger our immune systems will be as we grow older.

Here are two articles that I think you might find interesting.  The first is how bacteria and allergies are related.  The second is an episode from NPR’s Science Friday about the interaction of the bacteria in your body and its affect on your brain and your behavior.  Download the podcast and have fun learning!

 

 

 

Fetal cells live on in their mothers…..

This post goes out to my Biology students in particular, as we are currently studying about how cells are regulated in the body.  This article in Scientific American talks about a new study currently going on, in which cells were found in women that were distinctly not their own, but were in fact cells from their children!

“We all consider our bodies to be our own unique being, so the notion that we may harbor cells from other people in our bodies seems strange.”  Because these are embryonic cells, they are also stem cells, possessing the ability to differentiate into other cells in the body.
