Today we finished our Brain lab! It was a bit rushed in the end so please complete the remainder of the lab sheet. I will go over it on Wednesday. Keep this for your notes! You must know the major structures of the brain.
Please read the Teenage Brain article and use the response prompts from the previous blog post on mirror neurons to write. This will be due on Friday on your blog! A great video that goes along with this article is on the back of the article. http://www.cbc.ca/natureofthings/episodes/surviving-the-teenage-brain
Today we are learning everything about the brain by using our graphic organiser to assist us with brain surgery… with oranges! Please bring an orange to class!
Today I briefly went over The Nervous System and Endocrine System. Please use the handout I gave you to HIGHLIGHT key words we reviewed. You will have a quiz on Thursday on the following:
Neural Communication Quiz – You will need to review the following terminology/concepts.
Action Potential
Synapse
Dendrites
Axon
Cell body
Myelin Sheath
NT (Neurotransmitters)
Hormone
ACH
Nervous system and Endocrine (there will be 2 possible questions so only focus on your handout I gave you today on the terms we went over)
All or None response
Chart on Neurotransmitters (know the chart I gave you- dopamine, serotonin…)
FRQ question: Be able to explain how information travels in the nervous system, both within neurons and between neurons.
UPDATE ON MOVIE- AWAKENINGS
**I am giving you an option (bonus) to watch this movie and pick only ONE question to respond to on the blog. We watched some parts of it today but you will need to watch the remainder on your own time due to time as I need to move on for next class. This DVD is in our school library. If you would like to sign it out and watch it. I will leave this assignment as a bonus for term 1. The post can be done by the end of term! You may want to get together with a few students and sign out the DVD and watch the movie. It’s excellent and relates well to this unit. Please see me if you have questions.
What is L-Dopa?
Note: Antagonist Molecule- this blocks the NT’s functioning. In the movie they refer to L-Dopa. In order for drugs to have an effect on the body, there must be an accompanying receptor site on a neuron that matches the structure of that drug. So the body produces natural chemical substances that are similar to many of the drugs that affect the body. When we introduce drugs into our bodies, we are either increasing the amount of substances in the body or blocking substances that are suppose to work in a specific way.
But not all substances can pass through the body’s blood brain barrier which protects the brain from pathogens and harmful substances. For example- Parkinson’s patients cannot simply take dopamine to alleviate their symptoms . they must take a precursor of dopamine called L-dopa that will metabolize into dopamine once it reaches the brain.
Next Class – THE BRAIN
Quiz (25 minutes)
THE BRAIN using IPAD app- learning about different parts of the brain and functions. Discussion about the Teenage Brain
What a great class today! You are now all bloggers. Please make sure you have completed the following blog post on ONE of the questions below. Use your notes, textbook and classroom discussion to answer your question. I will go over examples of blog posts next day. For now, use your paragraph sample to help you get started.
PICK ONE QUESTION to BLOG ABOUT ON YOUR POST
What conditions are crucial for a civilization?
Do societies always deserve their reputation? (think about our discussion on the Vikings)
What does economic collapse do to society? (use the Anglo-Saxon experience as an example)
What was the impact of the Viking invasions on Medieval European society?
Please make sure you have completed the graphic organizer from today’s class. Answers below.
HW: Complete the Multiple Choice Test Practice and Written Response on the article I posted with handout on the previous blog post. Please post your response to your own blog. Also, keep in mind the tips on how to write a good response. Remember, you should now be using that handout as a guide to everything you write in this course. This will help with the Free Response Question.

WOW! Today’s Viking Commercials were amazing. Well done everyone. Looks like we are nearing the end to our unit. My hope is that you will be able to show me what you have learned in this unit with your first blog entry. Blog introduction will take place next week! Looking forward to it.
