FINAL POST :L
Hello B-Spot for the last time. :(
Well this will be my last blog seeing as it is coming to the end of our assessment task. I quite enjoyed this assessment task especially the part where everything except the hand out was on the computer. It was a change and change is good. Although the computers and laptops weren't working we some how managed to get everything done in the 2 weeks we had. My favourite part of this assessment was that we got every lesson from the day we got it to the day it was due to finish so that we didn't have to stress alot about it. Putting us students into groups was a good idea. One because we don't have to sit through the same presentation over and over again and two because we don't get confused and have like a major break down because we can't do it.
My group was the greatest!!!! Everyone did their part of the assessment and we kept each other on track of what each individual was doing just incase we needed to change something in our blogs. We each pitched in ideas for what to do and picked our own questions to do. Obviously I didn't pick my I was just told that's what question I was getting and I was fine with it. Everytime someone wanted to say somethine we all listened and no one was THE leader. Helping each other out was our way of doing everything and getting it done on time. Although we didn't get together after to and do our work or meet up in the library to do everything we did really good and I'm proud of the work we've done. The Digestive System was the best type of system to get because you could understand it more than any other system.
Each member in the group contributed in any way we could and we didn't even have to tell each other yu can do this we chode ourselves what we wanted to do.
I think overall this assessment helped us in 2 ways:
1. Have a broader knowledge on the different parts of the Digestive System and how they work and are effected.
2. Have more confidence in working with people outside of our friendship groups and be more indpendent with the work we are set and not leaving it to the last minute.
This assessment has taught me to take advantage of the time given to us by our teachers and not waste it by talking...hehe The knowledge I have collected throughout this process is quite large. When we actually get up in front of the class I think I'm going to also have the knowledge and the understanding of how hard it is to teach a class bigger than you in amount ways not size.
My favourtie part of this assessment was that we got to do whatever we wanted to do with the system we were allocated as longas we could teacher the class and widen their knowledge about it. Hopefully we do better than ever and no one will for asleep
Night B-Spot :)
Until next time....

Hand Out is Done !!!!
Hey B-Spot,
I'm so happy right now...I offically finished everythingg I had to do on my behalf of the group. I especially like the activity we are giving out to the class and the one we are doing in clas. The one we are doing in class is the one I was talking about in my previous blog. I reckon it's an AWESOME idea. With the handle I got a diagram from google and took away all the names and wrote them at the bottom along with one line of information that they have to match to the diagram. It's a simple and easy idea and no one will get bored with it because there isn't a lot of writting which we all know yr 8 students don't like to do. When I was done I printed 30 copies and I know we were meant to give it to miss to print it our so that we don't waste our ink but I really don't mind and I can just imagine the how many copies she would have to make for each group. That's a lot so I thought I might as well as print them out myself. Ms Manoogian also said that i could leave my Power Point on my USB until she figures out where she wants us to put it all.
that's it for this post

Hey B-Spot...
Today we are putting the little touches to our powerpoints.
and rubbing of the names of the parts as a revision kind of hand out and putting like questions on each question on the other side. I am printing out 30 copies so that their is enough and we are getting each student to draw a picture of the diagram and whoever has the best wins a packet of chocolate whichIi will buy tonight or 2morrow morning.
Today we are putting the little touches to our powerpoints.
Today is the last day we can finish off our assessment but Ms Manoogian said we had until 2morrow night to officially finish our assessment and all is done even the HAND-OUT. Tonight I'm going to work on our hand-out seeing as my section of our group work is done. We are planning on getting a diagram like this:

make up post.
On Tuesday I officially finished my Science Assessment and I'm so proud of myself. All those nights I stayed up until 2am paid off big time!!! At lunch time I went and made my Power Point which has 7 slide, one for each or some parts of the system and how it works. Hopefully I did everything right and I haven't left anything out.
Alex and Melanie are doing Bad Habits and When things go wrong in the one powerpoint because they link and Franchesca and I are putting What are the parts and How it works together because THEY intertwine.
Right now Franchesca and I have decided that she will take my part of the Power Point home and put nit together with her part.
Hopefully we are successful and are able to present on Monday.

When things go wrong??
Hey B-Spot...
Digestive System Problems
Nearly everyone has a digestive problem at one time or another. Some conditions, like indigestion or mild diarrhea, are common; they result in mild discomfort and get better on their own or are easy to treat. Others, such as inflammatory bowel disease (IBD), can be ongoing and troublesome and should be discussed with a GI specialist or gastroenterologist (doctors who specialize in the digestive system).
Problems With the Esophagus
Problems affecting the esophagus may be congenital (present at birth) or noncongenital (developed after birth). Examples include:
Congenital conditions. Tracheoesophageal fistula is a connection between the esophagus and the trachea (windpipe) where there shouldn't be one. In babies with esophageal atresia, the esophagus comes to a dead end instead of connecting to the stomach. Both conditions are usually detected soon after a baby is born — sometimes even before — and require surgery to repair.
Noncongenital conditions. Esophagitis (inflammation of the esophagus) can be caused by infection, certain medications, or gastroesophageal reflux disease (GERD). With GERD, the esophageal sphincter (the valve that connects the esophagus with the stomach) doesn't work well and allows the acidic contents of the stomach to move backward up into the esophagus. GERD often can be corrected through lifestyle changes, such as dietary adjustments. Sometimes, though, it requires treatment with medication.
Problems With the Stomach and Intestines
Almost everyone has experienced diarrhea or constipation. With diarrhea, muscle contractions move the contents of the intestines along too quickly and there isn't enough time for water to be absorbed before the feces are pushed out of the body. Constipation is the opposite: The contents of the large intestines do not move along fast enough and waste materials stay in the large intestine so long that too much water is removed and the feces become hard.
Other common stomach and intestinal disorders include:
Gastrointestinal infections can be caused by viruses, by bacteria (such as Salmonella, Shigella, Campylobacter, or E. coli), or by intestinal parasites (such as amebiasis and giardiasis). Abdominal pain or cramps, diarrhea, and sometimes vomiting are the common symptoms of gastrointestinal infections. These usually go away on their own without medicines or other treatment.
Appendicitis, an inflammation of the appendix, most often affects kids and teens between 11 and 20 years old, and requires surgery to correct. The classic symptoms of appendicitis are abdominal pain, fever, loss of appetite, and vomiting.
Gastritis and peptic ulcers arise when a bacterium, Helicobacter pylori, or the chronic use of drugs or certain medications weakens the protective mucous coating of the stomach and duodenum, allowing acid to get through to the sensitive lining beneath. This can irritate and inflame the lining of the stomach (gastritis) or cause peptic ulcers, which are sores or holes in the lining of the stomach or the duodenum that cause pain or bleeding. Medications usually successfully treat these conditions.
Inflammatory bowel disease (IBD) is chronic inflammation of the intestines that affects older kids, teens, and adults. There are two major types: ulcerative colitis, which usually affects just the rectum and the large intestine; and Crohn's disease, which can affect the whole gastrointestinal tract from the mouth to the anus as well as other parts of the body. They are treated with medications and, if necessary, intravenous (IV) feedings to provide nutrition. In some cases, surgery may be necessary to remove inflamed or damaged areas of the intestine.
Celiac disease is a disorder in which the digestive system is damaged by the response of the immune system to a protein called gluten, which is found in wheat, rye, and barley and a wide range of foods, from breakfast cereal to pizza crust. People with celiac disease have difficulty digesting the nutrients from their food and may experience diarrhea, abdominal pain, bloating, exhaustion, and depression when they eat foods with gluten. Symptoms can be managed by following a gluten-free diet. Celiac disease runs in families and can become active after some sort of stress, such as surgery or a viral infection. A doctor can diagnose celiac disease with a blood test and by taking a biopsy of the small intestine.
Irritable bowel syndrome (IBS), a common intestinal disorder, affects the colon and may cause recurrent abdominal cramps, bloating, constipation, and diarrhea. There is no cure, but IBS symptoms may be treated by changing eating habits, reducing stress, and making lifestyle changes. A doctor may also prescribe medications to relieve diarrhea or constipation. No one test is used to diagnose IBS, but a doctor may identify it based on symptoms, medical history, and a physical exam.
Problems With the Pancreas, Liver, and Gallbladder
Conditions affecting the pancreas, liver, and gallbladder often affect the ability of these organs to produce enzymes and other substances that aid in digestion. Examples include:
Cystic fibrosis is a chronic, inherited illness where the production of abnormally thick mucus blocks the ducts or passageways in the pancreas and prevents its digestive juices from entering the intestines, making it difficult to properly digest proteins and fats. This causes important nutrients to pass out of the body unused. To help manage their digestive problems, people with cystic fibrosis can take digestive enzymes and nutritional supplements.
Hepatitis, a condition with many different causes, is when the liver becomes inflamed and may lose its ability to function. Viral hepatitis, such as hepatitis A, B, or C, is highly contagious. Mild cases of hepatitis A can be treated at home; however, serious cases involving liver damage may require hospitalization.
The gallbladder can develop gallstones and become inflamed — a condition called cholecystitis. Although gallbladder conditions are uncommon in kids and teens, they can occur in those who have sickle cell anemia or are being treated with certain long-term medications.
Keeping Digestion on Track
The kinds and amounts of food a person eats and how the digestive system processes that food play key roles in maintaining good health. Eating a healthy diet is the best way to prevent common digestive problems.

20/8/10 Which Doctor?
The doctor that specializes on the digestive system is a gastroenterologist who studies gastroenterology.
Gastroenterology is the study of the digestive system. it covers pretty much everything about the digestive system. from the body parts and how it operates to its habits and diseases that can occur.
A major disease in the digestive system that can be prevented is LIVER CANCER.
Just abit...haha :P

19/8/10 Why do we need the Digestive System ?? -_-"
Hey B-Spot,
This is some info on the question "Why do we need it?"
We need the digestive system to get energy for our day! it provides our body with nutrients, nourishments and healthy blood cells. if you look at the whole of the body and you take out the digestive system, the chest and the stomach area would empty! in fact, there would be NO stomach area !!

20/8/10 GOOD HABITS BAD HABITS
Hey B-Spot,
Turns out we have to have a bit of an understanding of the information for the other questions...so here is some info on GOOD HABITS and BAD HABITS of the Digestive System
Good Habits that support your digestion include: drinking a lot of water so it can help the blood stream, eating and chewing your food SLOWLY, having foods high in fibre, making sure to have foods with nutrients and by leaving your stomach to only 80% full leaving 20% of your stomach unoccupied for room for digestion.
Bad Habits that DONT support your digestion include: smoking, taking drugs and drinking alchohol. These activities are OBVIOUSLY bad for your digestive system because you can get serious illnesses from these things. by consuming a lot of alchohol or taking drugs, something bad may happen to liver and your intestines.An example would be liver cancer.

Hey B-Spot,
Ohkaii well for my part of the presentation I am thinking of making a powerpoint and like having moving objects like food going through the system to show people what goes on in the body when they are eating.
Uhmm...also I think I'm going to bring in like a bag of chocolate Freddo's (hopefully no one is lack tose or is allergic to chocolate) and like use it as prizes for answering the question correctly or like I might give one out to each student and show them on the board what is happening to that Freddo, but I think it might be a bad idea because they might get turned off :S
So thats about it for now...if anyojne has any suggestions or has an opinion on this please comment and it might be helpful :)

Hey BLOGGY this is what I found today on Kids Health and this is the website http://kidshealth.org/kid/htbw/digestive_system.html
INFORMATION: So there you are, sitting at lunch, enjoying some grilled-chicken pizza and a few orange wedges. When you're finished, you take a last drink of milk, wipe your mouth, and head to your next class. In a few minutes you're thinking about the capital of Oregon or your science fair project. You've completely forgotten about that pizza lunch you just ate. But it's still in your stomach — sort of like a science experiment that happens all the time!
The Mouth Starts Everything Moving
Your digestive system started working even before you took the first bite of your pizza. And the digestive system will be busy at work on your chewed-up lunch for the next few hours — or sometimes days, depending upon what you've eaten. This process, called digestion, allows your body to get the nutrients and energy it needs from the food you eat. So let's find out what's happening to that pizza, orange, and milk.
Even before you eat, when you smell a tasty food, see it, or think about it, digestion begins. Saliva, or spit, begins to form in your mouth
When you do eat, the saliva breaks down the chemicals in the food a bit, which helps make the food mushy and easy to swallow. Your tongue helps out, pushing the food around while you chew with your teeth. When you're ready to swallow, the tongue pushes a tiny bit of mushed-up food called a bolus (say: bow-lus) toward the back of your throat and into the opening of your esophagus, the second part of the digestive tract.
On the Way DownThe esophagus is like a stretchy pipe that's about 10 inches (25 centimeters) long. It moves food from the back of your throat to your stomach. But also at the back of your throat is your windpipe, which allows air to come in and out of your body. When you swallow a small ball of mushed-up food or liquids, a special flap called the epiglottis flops down over the opening of your windpipe to make sure the food enters the esophagus and not the windpipe.
If you've ever drunk something too fast, started to cough, and heard someone say that your drink "went down the wrong way," the person meant that it went down your windpipe by mistake. This happens when the epiglottis doesn't have enough time to flop down, and you cough involuntarily (without thinking about it) to clear your windpipe.
Once food has entered the esophagus, it doesn't just drop right into your stomach. Instead, muscles in the walls of the esophagus move in a wavy way to slowly squeeze the food through the esophagus. This takes about 2 or 3 seconds.
See You in the StomachYour stomach, which is attached to the end of the esophagus, is a stretchy sack shaped like the letter J. It has three important jobs:
to store the food you've eatento break down the food into a liquidy mixtureto slowly empty that liquidy mixture into the small intestineThe stomach is like a mixer, churning and mashing together all the small balls of food that came down the esophagus into smaller and smaller pieces. It does this with help from the strong muscles in the walls of the stomach and gastric (say: gas-trik) juices that also come from the stomach's walls. In addition to breaking down food, gastric juices also help kill bacteria that might be in the eaten food.
Onward to the small intestine!
22 Feet Isn't Small at AllThe small intestine is a long tube that's about 1½ inches to 2 inches (about 3.5 to 5 centimeters) around, and it's packed inside you beneath your stomach. If you stretched out an adult's small intestine, it would be about 22 feet long (6.7 meters) — that's like 22 notebooks lined up end to end, all in a row!
The small intestine breaks down the food mixture even more so your body can absorb all the vitamins, minerals, proteins, carbohydrates, and fats. The grilled chicken on your pizza is full of proteins — and a little fat — and the small intestine can help extract them with a little help from three friends: the pancreas (say: pan-kree-us), liver, and gallbladder.
Those organs send different juices to the first part of the small intestine. These juices help to digest food and allow the body to absorb nutrients. The pancreas makes juices that help the body digest fats and protein. A juice from the liver called bile helps to absorb fats into the bloodstream. And the gallbladder serves as a warehouse for bile, storing it until the body needs it.
Your food may spend as long as 4 hours in the small intestine and will become a very thin, watery mixture. It's time well spent because, at the end of the journey, the nutrients from your pizza, orange, and milk can pass from the intestine into the blood. Once in the blood, your body is closer to benefiting from the complex carbohydrates in the pizza crust, the vitamin C in your orange, the protein in the chicken, and the calcium in your milk.
Next stop for these nutrients: the liver! And the leftover waste — parts of the food that your body can't use — goes on to the large intestine.
Love Your LiverThe nutrient-rich blood comes directly to the liver for processing. The liver filters out harmful substances or wastes, turning some of the waste into more bile. The liver even helps figure out how many nutrients will go to the rest of the body, and how many will stay behind in storage. For example, the liver stores certain vitamins and a type of sugar your body uses for energy.
That's One Large IntestineAt 3 or 4 inches around (about 7 to 10 centimeters), the large intestine is fatter than the small intestine and it's almost the last stop on the digestive tract. Like the small intestine, it is packed into the body, and would measure 5 feet (about 1.5 meters) long if you spread it out.
The large intestine has a tiny tube with a closed end coming off it called the appendix (say: uh-pen-dix). It's part of the digestive tract, but it doesn't seem to do anything, though it can cause big problems because it sometimes gets infected and needs to be removed.
Like we mentioned, after most of the nutrients are removed from the food mixture there is waste left over — stuff your body can't use. This stuff needs to be passed out of the body. Can you guess where it ends up? Well, here's a hint: It goes out with a flush.
Before it goes, it passes through the part of the large intestine called the colon (say: co-lun), which is where the body gets its last chance to absorb the water and some minerals into the blood. As the water leaves the waste product, what's left gets harder and harder as it keeps moving along, until it becomes a solid. Yep, it's poop (also called stool or a bowel movement).
The large intestine pushes the poop into the rectum (say: rek-tum), the very last stop on the digestive tract. The solid waste stays here until you are ready to go to the bathroom. When you go to the bathroom, you are getting rid of this solid waste by pushing it through the anus (say: ay-nus). There's the flush we were talking about!
Dig That Digestive SystemYou can help your digestive system by drinking water and eating a healthy diet that includes foods rich in fiber. High-fiber foods, like fruits, vegetables, and whole grains, make it easier for poop to pass through your system.
The digestive system is a pretty important part of your body. Without it, you couldn't get the nutrients you need to grow properly and stay healthy. And next time you sit down to lunch, you'll know where your food goes — from start to finish!

INFORMATION: So there you are, sitting at lunch, enjoying some grilled-chicken pizza and a few orange wedges. When you're finished, you take a last drink of milk, wipe your mouth, and head to your next class. In a few minutes you're thinking about the capital of Oregon or your science fair project. You've completely forgotten about that pizza lunch you just ate. But it's still in your stomach — sort of like a science experiment that happens all the time!
The Mouth Starts Everything Moving
Even before you eat, when you smell a tasty food, see it, or think about it, digestion begins. Saliva, or spit, begins to form in your mouth
When you do eat, the saliva breaks down the chemicals in the food a bit, which helps make the food mushy and easy to swallow. Your tongue helps out, pushing the food around while you chew with your teeth. When you're ready to swallow, the tongue pushes a tiny bit of mushed-up food called a bolus (say: bow-lus) toward the back of your throat and into the opening of your esophagus, the second part of the digestive tract.
On the Way DownThe esophagus is like a stretchy pipe that's about 10 inches (25 centimeters) long. It moves food from the back of your throat to your stomach. But also at the back of your throat is your windpipe, which allows air to come in and out of your body. When you swallow a small ball of mushed-up food or liquids, a special flap called the epiglottis flops down over the opening of your windpipe to make sure the food enters the esophagus and not the windpipe.
If you've ever drunk something too fast, started to cough, and heard someone say that your drink "went down the wrong way," the person meant that it went down your windpipe by mistake. This happens when the epiglottis doesn't have enough time to flop down, and you cough involuntarily (without thinking about it) to clear your windpipe.
Once food has entered the esophagus, it doesn't just drop right into your stomach. Instead, muscles in the walls of the esophagus move in a wavy way to slowly squeeze the food through the esophagus. This takes about 2 or 3 seconds.
See You in the StomachYour stomach, which is attached to the end of the esophagus, is a stretchy sack shaped like the letter J. It has three important jobs:
to store the food you've eatento break down the food into a liquidy mixtureto slowly empty that liquidy mixture into the small intestineThe stomach is like a mixer, churning and mashing together all the small balls of food that came down the esophagus into smaller and smaller pieces. It does this with help from the strong muscles in the walls of the stomach and gastric (say: gas-trik) juices that also come from the stomach's walls. In addition to breaking down food, gastric juices also help kill bacteria that might be in the eaten food.
Onward to the small intestine!
22 Feet Isn't Small at AllThe small intestine is a long tube that's about 1½ inches to 2 inches (about 3.5 to 5 centimeters) around, and it's packed inside you beneath your stomach. If you stretched out an adult's small intestine, it would be about 22 feet long (6.7 meters) — that's like 22 notebooks lined up end to end, all in a row!
The small intestine breaks down the food mixture even more so your body can absorb all the vitamins, minerals, proteins, carbohydrates, and fats. The grilled chicken on your pizza is full of proteins — and a little fat — and the small intestine can help extract them with a little help from three friends: the pancreas (say: pan-kree-us), liver, and gallbladder.
Those organs send different juices to the first part of the small intestine. These juices help to digest food and allow the body to absorb nutrients. The pancreas makes juices that help the body digest fats and protein. A juice from the liver called bile helps to absorb fats into the bloodstream. And the gallbladder serves as a warehouse for bile, storing it until the body needs it.
Your food may spend as long as 4 hours in the small intestine and will become a very thin, watery mixture. It's time well spent because, at the end of the journey, the nutrients from your pizza, orange, and milk can pass from the intestine into the blood. Once in the blood, your body is closer to benefiting from the complex carbohydrates in the pizza crust, the vitamin C in your orange, the protein in the chicken, and the calcium in your milk.
Next stop for these nutrients: the liver! And the leftover waste — parts of the food that your body can't use — goes on to the large intestine.
Love Your LiverThe nutrient-rich blood comes directly to the liver for processing. The liver filters out harmful substances or wastes, turning some of the waste into more bile. The liver even helps figure out how many nutrients will go to the rest of the body, and how many will stay behind in storage. For example, the liver stores certain vitamins and a type of sugar your body uses for energy.
That's One Large IntestineAt 3 or 4 inches around (about 7 to 10 centimeters), the large intestine is fatter than the small intestine and it's almost the last stop on the digestive tract. Like the small intestine, it is packed into the body, and would measure 5 feet (about 1.5 meters) long if you spread it out.
The large intestine has a tiny tube with a closed end coming off it called the appendix (say: uh-pen-dix). It's part of the digestive tract, but it doesn't seem to do anything, though it can cause big problems because it sometimes gets infected and needs to be removed.
Like we mentioned, after most of the nutrients are removed from the food mixture there is waste left over — stuff your body can't use. This stuff needs to be passed out of the body. Can you guess where it ends up? Well, here's a hint: It goes out with a flush.
Before it goes, it passes through the part of the large intestine called the colon (say: co-lun), which is where the body gets its last chance to absorb the water and some minerals into the blood. As the water leaves the waste product, what's left gets harder and harder as it keeps moving along, until it becomes a solid. Yep, it's poop (also called stool or a bowel movement).
The large intestine pushes the poop into the rectum (say: rek-tum), the very last stop on the digestive tract. The solid waste stays here until you are ready to go to the bathroom. When you go to the bathroom, you are getting rid of this solid waste by pushing it through the anus (say: ay-nus). There's the flush we were talking about!

9/8/10
Hi there blogspot,
On the 9/8/10 we were in the library and were unable to blog because of the situation with the internet. We researched using books and the book I collected most of my information from was How the Body Works by Steve Parker. The info didn't really explain much soo I didnt make much progress.
Anyways that's prety much it
Blog you latahh :)

Day 2: 6/8/10
Hey Again Blogspot...
Today we officially started our research on our assessment task. The question I'm doing is "How does it work?". Alex is doing questions "Why do we need it?" and "When things go wrong?". Melanie is doing questions "Good Habits" and "Bad Habits". Franchesca is doing "What parts make up the system?" and "Which Doctor?". I've only got one question because the rest picked 2 and I was last to keep.
Well that's it for another hour :)
Milla :P

Day 1: 4/8/10
Hey Blogspot...
Well today we had to make a group of 4, for our assessment task in Science and I'm with Franchesca, Alex and Melanie. The system of the body we are doing is the Digestive System. I'm blogging because it's part of my assessment task to blog about what you do in Science when your working on your assessment.
Well that's all for this hour of Science..blog you later.
