The Immune System and Germs

    Today we started a new part in our Science unit of cells. We started talking about how our body natural pretects itself, things like barfing, sneezing, coughing, etc. We also talked about the immune system and germs. We talked about bacteria which are Uni-cellular organisms that can affect the human body in both a negative or positive way. Another type of germ we learned about was a virus. A virus is a multi-cellular organism that when it enters an organism it takes over, or infects, a cell that is already in the organisms body, usually in a negative way. Pathogen was another germ we talked about. When a bacteria affects you in a negative way (like a disease) , the bacteria is refered to as pathogen. You are probably wondering what your body does to prevent these things, well we learned about that to. Our first defence's are things like your skin, earwax,saliva, and gastric acids (in your stomach). They aren't very reliabal though because they will try to stop both negative and positive germs, and they don't stop every germ. The quicker your body can catch germs at this defence level, the better. Your body's second defence comes into play once germs get through the first defence and into the blood stream. The secondary defence is much more agressivethen the first. They can tell the differece between negative and positive germs and target all the negative germs.

Can you answer some of the math teasers?
   1) A ship anchored in a port has a ladder which hangs over the side. The length of the ladder is 200cm, the distance between each rung in 20cm and the bottom rung touches the water. The tide rises at a rate of 10cm an hour. When will the water reach the fifth rung?

   2) I am an odd number. Take away one letter and I become even. What number am I?

3) A school bus travels from Veldhoven to Roosendaal. There are four children in the bus. Each child has four backpacks with him. There are four dogs sitting in each backpack. Every dog has four puppies with her. All these dogs have four legs, with four toes at each leg.

Heres a little funny math picture!!

Today we started a new unit!!  We started off by reviewing what we visited so far!
We reviewed ~The Six Characteristics of life
                      ~Cell Theory
                      ~Animal and Plant cells
                      ~Medicine Wheel
                      ~ How Cells Move ---How Cells Move (Different blog)
                      ~The Heart
When we finished, we decided to watch "The Heart" By Mr Parr.

We then made our own Wordle Review! This is the outcome of our hard work!! We all carefully chose words and (of course) we all had our input on the colours.

Have A Heart
Todays class we were working on a work sheet called Have A Heart. We had to label some of the parts of the heart, such as: Left atrium, Right atrium, Left ventricle, Right ventricle, Body capillaries, Lung capillaries, Veins, Heart and the arterys.  (Sorry that the picture is on its side)

Have a Heart!(2013).created by McGraw-Hill Ryerson Ltm. picture taken by myself

Can you anwser some of the questions?
1) Which side of the heart collects blood from the body and pumps it to the lungs?
2) Which chamber receives blood form the lungs?
3) Which ventricle is more muscular, the right or the left?

PROCEDURE         For our experiment we went into Mr. Hazelwoods lab. When we got there, we saw fullgrown bulls heart sitting in a pan, a scalple, cool frog aprons, and plastic gloves. We also had a pair of scissors, but we never used them. We were told the rules of the lab and what we were supposed to do to the heart. After we found out which way the heart was facing, Kurtis started recording. Paul labeled the exterior parts of the heart. After he was finished, Steven started to cut the heart (carefully) in half with the scalple. Once steven cut open the heart, Mrs. Thompson told us that the chambers were cleaned out. It turns out there was a very andry women in Rorkton, Manitoba that got the hearts with all the veins and openings where al the valves were. She was supposed to serve them to people too (I would NEVER eat a heart!!). After that wierd story We poked around inside a little bit. It was pretty cold and slimey. When we were done ME labled the internal parts of the heart. Then DEZ labeled the blood flow with some yarn. Than we plated with it a little more. Our next step was to cut of all of the  fat and predict how much fat to muscle there was in total. We were told to turn it into a percent, a fraction and a decimal. When we finished we took the heart to Mrs. Thompson, off our gloves and aprons, washed out the pans and utensils,  washed down the tables, and washed our hands.

DATA       Over all we think we did pretty good (eventhough ME was very discusted). We predicted the heart was about 30% fat, and 70% muscle. (30% = 3/10 = 0.3) We all agree the heart is very complex and intricate.

CONCLUSION       In conclusion we found out that the heart is very interesting. It is a a very powerful muscle. We think our experiment wnt pretty smoothly. Nobody threwup (although ME was close), nobody got hurt, and  it was pretty fun. We learned alot about how the heart works, and how a real  heart looks like! We found this experiment alot more helpful than writing a bunch of notes for helping us understand the matters of the heart. Overall it was a pretty terrific day.

The Main Muscle!

                                                        The Main Muscle
                                            Dez, Steven,Kurt,Paul and ME!!!

Abstract: Have you ever wondered what the muscle keeping you alive looks like. It is not shaped like the heart we all know how to draw. It looks more like a football shape. Guess what? We cut open a full grown heart! It was kind of hard, but some parts were squishy! Our goal was too what a heart acutally looks like in real life, instead of just seeing pictures.

 Work in progress to be completed November 20th

MATHLETE FRIDAY!!!!!!!!!!!!!!!!


                   Using only addition, how do you add eight 8’s and get the number 1000?


          Sally is 54 years old and her mother is 80, how many years ago was Sally’s mother three times her age?


           There is a basket containing 5 apples, how do you divide the apples among 5 children so that each child has 1 apple while 1 apple remains in the basket?

       There is a three digit number. The second digit is four times as big as the third digit, while the first digit is three less than the second digit. What is the number?

First Formal Lab Rules

    HEART DISSECTION DISCUSSION                                             

Each person writes one of following:(Can use notes from binder)
                               -labels exterios parts
                              -labels interios parts
                               -labels blood flow
              one person cuts with the scapel
must cut correctly to see four chambers of heart
we also discussedwhat we would seeand how we should do this.

This is our heart! We are finished and this is our final copy. We all agreed that this is the best that we could posibly do. It follows all of the standards that are needed.

( click STANDARDS THAT  to see the standards!)

BY ME!! was responsible for drawing the original copy of the heart, and labeling most of the diagrams.

Dez had drawn the rough copy of the internal part of the heart, decorated, and she also wrote down the way the blood flows.

Josee outlined the second heart of the good copy, helped colour, decorate and read the information for BY ME!! to write it down.

Landen helped colour, outline, and he read off information.

Heart Diagram

We are working on our heart diagrams. So far most groups have gotten to making their good copy on big poster paper. There are supposed to be two hearts, that are exactly the same size, but showing exterior and interior. To make the first part of the heart to be almost exactly the same size as the second, we have to cut out our first heart and trace it. After we finish drawing the hearts, we are suppose to label them and alo colour them. We got some pictures to look off for when we draw our hearts, to help us get an idea of what a heart actually looks like.

Heart Diagrams

We started planing out haert diagrams of interrior and exterrior in our table groups of three or four.
Our marks are out of 40.

The Box of Mystery

The amount of blood thats in our body

In the box of mystery, we are looking at the amount of blood that is in  our body. There is about six quarts of blood in our whole body at one time.

In one day our blood travels 11,999.994 miles around our whole body. We determend this by walking across the school from end to end. then we multiplyed our aswer by 84507
