Monday and Tuesday June 3rd and 4th

We are in the final stretch of our Unit on Skin and Skin Cancer.
We discussed who is at risk for skin cancer and the treatments.

The final assignment can be viewed here.

Here is the link to the Skin Unit Project site

Today (Tuesday) we welcome Dr. Janice Pelletier into our class.  Dr. Jan wrote a bill to ban tanning for adolescents under the age of 18.  She will discuss the science and process behind her actions.  

Here are some links to "Skin Cancer in the News" and editorials written around the bill.

May 28th - Introduction to the Integumentary System...in simple terms your skin!

Here is a link to a web site we have set up for you to learn about your skin and the effects of UV Rays.  

Click here to access the web site.

We are fortunate to have Mrs. Erin VanWagenen a local doctor to help us out with some of the content.

Today we will be learning about the structure and function of our skin.

Here is the link to the homework webquest investigation EM Spectrum and UV Rays.

Here is the link to the FDA site.

Some cool facts to get us started:

• Skin is your largest organ in your body!
• Your skin accounts for 15% of your body weight!
• Over 50% of dust in your home is dead skin.....YUCK!
• Your skin has its own micro-biome...over 1,000 species of bacteria on it.
• It takes babies 6 months to develop their permanent skin tone.  

Skeletal System - Composition of Bones and Review

Here are some links to some review items on the skeletal system:

• cancellous (spongy) bone
• bone marrow (red and yellow)

Here is a link to a great video on the composition of bone by National Geographic.

Monday April 29th - Wrapping up the Circulatory System

Hi All,

Today we are finishing up our work on the circulatory system.

Here is a review video to watch on the blood flow.



After you are done watching this you can go to this link and complete the interactive quiz.
Label the Heart

Here is one more link from Nova on the Human Heart.

Here is the image of the hear that you will use to trace the blood flow.  Remember you will have a word ban kto help you out, but you need to identify the parts and how the blood moves.

Monday April 22nd

Today we introduced the Disease/Disorder of the Week Project.

Click here to link to the project site.

Topics are due Thursday!

Email Mr. Cuthbert your top 3 choices AND why you chose them.

Wednesday, April 3, 2013

We had some excellent discussions today about the relationship between photosynthesis and respiration.  It is always great to see that a lot of critical thinking is taking place!

During class, we talked about fermentation including alcoholic fermentation in yeast and lactic acid fermentation in the muscles of humans.

Also, we kicked off class with a gallery walk for students to share their illustrations and poems depicting photosynthesis and respiration.  Here is a lovely example of student work:

Wednesday -Thursday 20- 21st - Study Guide and Comparing Active and Passive Transport

Today we made a comparison between active and passive transport using a Double Bubble graphic organizer.

Here are some pictures of the carousel activity that we completed Wednesday.

Here is a link to the the online BBC Webquest.  I emailed this to your school accounts as well in a Pages format so you can type right into it.

Here is the Cell Transport Study Guide for Friday's Quiz.

Here is a final BBC Video that is very good on osmosis and diffusion.

Here are a few good review question on plant cell osmosis.

Here is a great visual of the effect of osmosis and blood cells.

Here is a look into today's review session using a cafe style review technique.

Active Transport - March 18th 2013

Today we were introduced to the second form of cell transport, active transport.
Active transport is when energy is needed to be used to move molecules from low concentration to high concentration across a cell membrane.  Often in this form of transport, transport proteins are used to aid the process.

Here is an image of active transport.

Here is a link comparing of active and passive transport.

Here is a video showing active transport in terms of the sodium/ potassium pump.

Monday March 11th - Cell Transport

Today we will be starting a Unit on Cell Transport (active and passive).

Here are the notes from today's class.  Click here to access.
Today in class we will add to these notes filling in examples of each of the vocabulary terms from demonstrations performed in class.


Here are some interactive links showing diffusion of molecules - a form of passive transport.

Meiosis vs Mitosis - Week of March 4th

When you are done your DNA models, check them with a teacher and then start work on the Mitosis vs Meiosis 
Webquest below.
Mitosis vs Meiosis Webquest Worksheet.

After you have completed the webquest view a few of the below videos.  Pay close attention to the following:
1. How many daughter cells are found at the end of each cell division?
2. What is the function of each division and which cells do they occur in?
3. How many chromosomes are found in the daughter cells compared to the mother cells?
4. How many divisions and interphases does each go through?

Thursday 28th -DNA Modeling and Genes and your Health

We will be constructing DNA models using one of the three methods:

• Bead Jewelry
• Origami or
• Candy

The point of the activity is to be able to correctly identify the smaller parts that make up a DNA Molecule .

Here is the DNA Model Rubric

When you are done with your model...

Here is the link to the Nobel Prize Game on DNA Replication.  Be sure to use the correct base pairs!

Finally, here is a link to a reading on cholesterol genes to your health.

Welcome Back - Feb 25th and 26th 2013

Welcome back from a wonderful break!

We are going to continue our work with Cell Reproduction.  Specifically we are going to look at DNA and how it makes up the chromosomes in your body.

The following are two great readings on DNA.
1. Science for Kids Link- DNA
2. Kidipede - Genetics for Kids


Here is a link to an interactive site on DNA:
1. Tour of the Basics  - from the University of Utah - Choose "What is a Chromosome?"


Here are two good videos explaining the relationship between DNA, genes, histones, chromatin, chromatids, and chromosomes.

Wednesday February 13th

Today students will complete the in class Cell Cycle Simulation using pipe cleaners and transparencies to show the different stages of the cell cycle.  Students will show the movement and changes that the cell's chromosomes go through as the cell divides.

Once students complete the task they will import their pictures into a Pages document and supply a description labeling the major changes in each of the pictures.

Here is an example of the layout:

Finally, when students complete the document they can access the online webquest here.
Be sure to go through the directions carefully and record the information when it is asked for.
