Atomic Bomb Debate

If it had to be done all over, should we have dropped the atomic bomb?  You will debate this decision based on one of four points of view: a scientist, a Truman advisor, a military officer, or a Japanese survivor.

Here are some websites that can help you...

Blood Typing Tutorial

Watch this tonight and fill out your note sheet for Wednesday.  We will go over the information in class on Wednesday and do more Punnett Squares with blood types!  :)

Punnett Squares and Genetics

    
Be sure to add the notes I emailed to you into your One Note!  Try these "practice problems" out using a Punnett Square.

C=curly hair (UPPER CASE "C")
c= straight hair (lower case "c")

1. If the Mom is HETEROZYGOUS curly (Cc) and the dad is HOMOZYGOUS straight (cc), what are the possiblities for their offspring?  Give in percentages.


2. If the mom and dad are both Homozygous Dominant, what will the outcomes be for their offspring?


3. Both parents are heterozygous.  Could they have a child with straight hair???

(Answers are in the file cabinet! :)

If you need a little tutorial, check out this video for Punnett Square help!  You only need to watch the first 5 minutes of it!  We have not covered the rest of the video yet!  It will be helpful later though!

DNA

Isn't it amazing to think this is ACTUALLY happening in your body RIGHT NOW??  This video shows DNA Replication (which you MUST know) and transcription (you do NOT need to know this for the quiz Friday).

Cell Size Lab

Why are cells so small?  Well, we discussed this in class today.  It has to do with the surface area-to-volume ratio.  Small cells have a larger surface area-to-volume ratio than larger cells as we  saw with our cubes that represented.  If you are still having some problems with this, try watching this video.  This guy is one of my favorites!  Watch this video for help!

The Cell Membrane

Important MUST KNOW terms on the cell membrane:

• Diffusion
• Osmosis
• Semipermeable Membrane
• Passive Transport
• Active Transport

Passive Transport:

  

Active Transport:

Cells Theory

For Review:

Anton Von Leewenhoek looked at pond water and saw "animalcules"

Robert Hooke named the "little rooms" that he saw cells

Theodor Schwann, Matthias Schleiden came up with the Cell Theory:

1. Cells are the basic unit of life

2. All living things are made up of one or more cells

3. All cells come from other living cells

Analyzing What We Eat

Monday we are looking at the results of our food trackers.  Hopefully, you are a healthy eater!  Of course, we all need dessert sometimes!!

Tuesday, in class, we are going to produce a full day's worth of healthy meals.  Check the following document for an Extra Credit Opportunity.  You will need to sign up!!

https://docs.google.com/document/d/1xHCPljxV2SWHI4DMv2469oNeHWUFid8ktwvuLi5YeEE/edit

Nutrition

Homework for Monday, September 17th- You need to keep track of EVERYTHING you eat and drink for three days between now and Monday.  You can choose whatever days you'd like.  Have your parents help you with meals.  Click on the button to log in to your SuperTracker account.  Don't panic if you can't find a food, we'll go over problems in class.  If you are not liking the SuperTracker site, try SparkPeople.  It seems much easier to use, however, you need to have your parent sign you up for it.  The purpose of this assignment is not to diet, but to keep track of your calories, protein, fat, and carbohydrates.  You will need to print to OneNote the results of each day's food totals.

** If the online trackers are not working for you, you will need to write out everything you eat for 3 days.  That includes name of the food,serving size, calories, fat, protein, and carbohydrates!  

            

Metric System Information

Science always uses the Metric System for measurements.  It really is easy!  Check out these sites to review.

http://www.themetricsystem.info/ There is good basic information here.  Check out the "How to Learn the Metric System".  It provides a Celsius "temperature poem" which is a good way to remember the basic temperatures in Celsius.

Here is what I used for the Power Points and worksheets today.

5 Kingdom Review

Use this /Quizlet site to review at the beginning of class. Once you are done reviewing, take the TEST to see if you can pass with an 80% or better! http://quizlet.com/5396227/kingdom-classification-quiz-562011-flash-cards/

 The Most AWESOME site ever! We will be using this as we learn about microscopic organisms and metrics in biology: http://www.numbersleuth.org/universe/

Kingdom Protista (Protists)

The Protist Kingdom has been called the "junk drawer" of the classification system. Things that scientists don't know where to fit otherwise get placed in the Protist Kingdom!  Most of the time Protists are:

• single-celled
• Eukaryotic (they have a nuclear membrane)
• Some are "animal-like"- they move, and have to get their food
• Others are "plant-like" - don't move and make their own food (photosynthesize)
• Many are found in pond water 

You will be looking at Protists this week while we study micro

Welcome New 7th Graders!!!

Rafting with my family...notice my son's face!  Big rapids coming up!

Hello 7th Graders!

I hope you are as ready for the new school year as I am!  It is going to be such an awesome year having your own laptop everyday in the classroom!

What a summer I've had!  I camped and played in Colorado where it was cool.  My family got a new dog named Summer.  I hung out with my kids while they golfed, played tennis, competed in swim meets, and played basketball.  I took several classes and taught a summer class.  I read a TON of books!  And, I went to Memphis, Tennessee to learn how to effectively use laptops in the classroom.  I'm ready for school to begin!

I would love to hear from you before school begins.  Take the short survey below to help me find out a little bit about you!  Enjoy these last few days.  I can't wait to meet all of you!

Sincerely,
Mrs. Dokken :)

Skin

Skin Facts

SPF= Sun Protection Factor

SPF 15- means if you burn in the sun after 10 minutes, then with the SPF 15, you can stay in the sun 150 times longer (10 X 15= 150) before burning. 

·        SPF 15 filters about 93% of the sunlight.

·        SPF 30 filters about 97% of sunlight.  (30 is not twice as strong as 15!)

UVA vs UVB-

http://www.skincancer.org/prevention/uva-and-uvb/understanding-uva-and-uvb

          UVA= Long light waves—responsible for wrinkles

          UVB= Short light waves—responsible for tanning/burns

UV light is the main cause of non-melanoma cancers!!

Wrinkles:

·         Skin ages all over the body, but much more so where there has been sun exposure. Changes brought on by sun damage (photoaging) include "dryness" (really roughness), sagginess, skin growths like keratoses ("liver spots"), and wrinkles.

·         Wrinkles in turn can be divided into two categories; fine surface lines and deep furrows. Wrinkle treatments are in general much more effective for fine lines. Deeper creases may require more aggressive techniques, such as plastic surgery.

·         Factors that promote wrinkling include smoking; skin type (people with light-colored skin and blue eyes are more susceptible to sun damage); heredity (some families wrinkle more); hairstyle (depending on how much skin is covered by hair and protected from the sun); dress (again, by determining which skin is exposed); and occupational and recreational sun exposure over the course of many years.

·         Treatments available for wrinkles include medical treatments (such as vitamin A acid, alpha hydroxy acids, antioxidants, and moisturizer) and cosmetic procedures (such as glycolic acids peels, deep peels, dermabrasion, laser resurfacing, surgical procedures, and Botox).

·         The number of epidermal cells decreases by 10% per decade and they divide more slowly as we age making the skin less able to repair itself quickly.  The epidermal cells become thinner and less sticky.

·         Botox for wrinkles!- check out more information of this toxin/medicine at http://en.wikipedia.org/wiki/Botulinum_toxin

Tattoos:

Permanent insoluble ink that is placed about 1 millimeter into the dermis layer of the skin.
