Immune System Demo
The point of the immune system is to fight off against bacteria, viruses, and infections. The first line of defense consists of the skin, mucus, and pH. Pathogeons are any substance that could cause harm or disease to the body, such as fungi, proteins, parasites, and bacteria. The second line of defense is inflammatory response, phagocytes, and fever.

Viruses are everywhere, from the food we eat to everywhere in our surroundings.
We take in millions of viruses every second, by inhaling
Contains DNA or RNA and enzymes for replication
Virus- a single or double strand of DNA or RNA which the virus uses as its genome, but it cannot reproduce by itself. That is when the virus finds a cell and converts them so they are a mindless virus.

Pond Water Quality

Pond is defined as a body of water where no other water is being added, and sunlight that can be reached all the way to the bottom

Macroscopic- animals or organisms able to be seen without a microscope

Tartigrades, are located in every pond except some desert ponds

Ponds are stagnant

184 different types of bacteria on average in ponds, mostly which are good for you

Too much or too little bacteria can cause the enviornment to collapse

Chlorine and Lead in tap water we drink

Tap water comes from rivers sewer ponds and ground

Only 2% is potable which means it is safe to drink

Chlorine is a toxic, irritant, and a palegreen gas in its natural state

It kills bacteria and microbiological organisms

Chlorine reacts easy with other chemicals, and has a low harm

Lead is first cut it is a blue white color, but once it reacts to the air it turns black

It is not safe to drink, but you can touch it

It can get into the water if it is in the pipes and gets carried throughout the water

Lead affects the enviormnent by air pollution, moves through the ecosystem, if an animal eats it and carries it throughout

Organ damage, it can damage brain growth for children

Station 2-pH of ocean water

normal range of ocean water is between 6-8

a low number is acidic

enviornment can affect the pH levels of the ocean

pH finder is filter paper filled with pH indicators

Water Cycle Demo

-100ml of water heated into a microwave for 2 minutes

-6ml of salt

-plastic wrap

(creating ocean water) Take a cup of as if it was lake then put plastic wrap over up as an ozone layer (greenhouse affect). As sun hits the ocean causing it to heat the water molecules making it evaporate and as it rises the temperature declines then when it cools condesense to make precipitation. It goes from liquid water to water vapor then condenses into water droplets to form clouds then falls from the sky which is rain or could be snow. The water soaks into the soil and then transports to the lakes and underground aquiliers.

My group and i did a water slide project, where we were given 30 minutes to make the highest, or steepest water slide possible, while still letting an action figure guy go down, without being suffocated or injured. Each of my group members brought in one item from home, and we were aloud to use any supplies we could find in the makers space. My group and i decided to cut my Mental Health unit project in half, and use it for the base, and the place the action figure would go down. We then took cardboard from the makers space, which was already folded to make a slide like shape, and ran it down from the top of the unit project board, and put it all the way to the ground. We inferred the action figure would not go down just on the cardboard, so we took plastic bags one of my group mates brought, and ran them from the top of the slide, down to the bottom. In the end, we didn't win because our figure got trapped in the beginning, but came out successfully.

Friars Real Plan- Exposed?

Introduction: In William Shakespeare’s play, Romeo and Juliet, it is very clear that Romeo and Juliet have a variety of mental health issues and disorders. The mental health issues made it so it was easy to believe that they killed themselves, but that was not the case. It has come to attention that there was DNA found at the crime scene that did not match Romeo or Juliet. The DNA matched with a man very well respected by the Capulets and Montagues, his name is Friar Laurence. Purpose: After observing 5 suspects’ DNAs, whose DNA matched up with the murderer of Romeo and Juliet? Hypothesis: If Friar Laurence killed Romeo and Juliet, then his DNA will line up with the murderer’s DNA because he wanted the Capulets and Montagues to stop feuding which would not have happened if one of them was dead and the other lived. Materials: 50 ml 0.9 percent salt water 5 disposable plastic cups 5 large test tubes (15 ml with screw on caps) 25 mL liquid detergent 75 mL water 25 ml 95 percent ethanol, chilled on ice 5 small test tubes 0.25 mL methylene blue solution per DNA sample Pipette and disposable pipette tips 5g Baking soda Agar powder 200 mL Deionized water 5 drops glycerin (1 drop per) Stainless steel wire Wire cutters Scissors 45 volt power supply 2 alligator clip leads Flat piece of Styrofoam for the comb One plastic box, big enough to hold the gel 500ml of deionized water 5g baking soda 5 grams agarose Separate container for mixing materials (a bowl is suggested) Butter Knife Procedure: Creating the Gel Electrophoresis Chamber: Cut two pieces of stainless steel wires that are roughly 1 inch longer than the longest length of the box. Bend the wires along the shortest width of the bin so that they touch the bottom. The excess wire should be hooked to the edge of the bin so it stays in place. Once the wires have been shaped, remove them from the box and keep them in a safe place. Create a comb using styrofoam. Make sure the top part of the comb is wide enough to rest on the edges of the plastic bin. The bristles should end at least 2 millimeters above the bottom of the plastic bin. Make one tooth for each suspect that is being tested. The distance between each tooth should be evenly spaced. Place the comb into one end of the plastic bin.           Creating the Gel Make a 1% solution of baking soda for the new buffer solution. Measure 2 grams of baking soda and add it to 200 mL of bottled water. Stir this mixture well. Make a 1% agarose solution. This can be accomplished by combining 1 g of agar powder with 100 ml of the buffer solution made in the previous step. Heat the agar solution on a hot plate or in a microwave. In the microwave stop the timer every 10-15 seconds to stir the solution. If it is heated on the hot plate make sure it is stirred often throughout the heating process. When the solution starts to bubble, take it off the hot plate or remove it from the microwave. The solution should appear translucent.     After the agarose solution is made, pour the it into the plastic bin. The solution should fill the bin up and cover most of the comb.        Collecting DNA Samples: Have each murder suspect swish 2 teaspoons (10 ml) 0.9 percent salt water in their mouth for 30 seconds. Spit the water into their cup. Each suspect should be using a different cup, no sharing! Make a 25% mild detergent solution by combining 5 ml of liquid detergent and 15 ml of water. There should be enough of the solution for each suspect. Take 5 ml of each DNA sample them in their own test tube. Label each test tube according to what DNA it contains Add 5 ml of the 25% mild detergent solution to each test tube. Cap each test tube and swish them on their sides for 2-3 minutes. Be careful when rocking the solutions so that the DNA does not forcefully break apart. Open the tube and add 5 ml of the chilled 95% ethanol to the tube. It will form a layer on the top of the DNA solution. Allow the tubes to stand for 1 minute. While the tubes are standing, label one micro test tube for each regular sized test tube. Use a syringe or eyedropper to take 0.25 ml DNA from the top of each test tube. Add each DNA to it’s own micro test tube. Make sure that a new eyedropper is used for each DNA sample. Use the disposable pipettes to add 0.25 ml methylene blue solution to each micro test tube. Add one drop of glycerin to the micro test tube with the DNA/methylene blue solution. Close the test tubes tightly until they are ready to be put in the gel electrophoresis box. Testing the Results:      Make a 1% solution of baking soda for the new buffer solution. Measure 2 grams of baking soda and add it to 200 mL of bottled water. Stir this mixture well. Make a 1% agarose solution. This can be accomplished by combining 1 g of agar powder with 100 ml of the buffer solution made in the previous step. Heat the agar solution on a hot plate or in a microwave. In the microwave stop the timer every 10-15 seconds to stir the solution. If it is heated on the hot plate make sure it is stirred often throughout the heating process. When the solution starts to bubble, take it off the hot plate or remove it from the microwave. The solution should appear translucent.     After the agarose solution is made, pour the it into the plastic bin. Carefully remove the comb from the solidified gel. The indents from the comb will be where the DNA is placed later. Use the butter knife to cut a thin slice of gel from both the top and bottom. These cuts will fit the wires Fit the stainless steel wire (electrodes) into the cuts made in the previous step. Use an eyedropper or syringe to fill each well in the gel with a different suspect’s DNA. Be sure to record what DNA solution is placed in which well. Pour the buffer solution over the gel once it has set. If necessary, make more buffer solution to cover all of the gel. Data Table: Suspect Travel Distance of DNA Bands (cm) Suspect #1: Friar Laurence Results Inconclusive Suspect #3: Montague Results Inconclusive Suspect #8: Benvolio Results Inconclusive Suspect #9: Paris Results Inconclusive Suspect #10: Capulet Results Inconclusive Identify the Independent and Dependent Variable: X: Suspects Y: DNA’s Distance Graph:        #1 Scatterplot (With fake data)     #2 (Should be) Scatterplot with actual data                                                                  Paragraph One: Due to the DNA found at the crime scene of Romeo and Juliet’s death, the match was Friar Laurence. There was no data collected, because of the large amount of obstacles we encountered. Some of the problems were the gel we made, was too hard which would had made collecting the data and results from it, almost impossible and very difficult. Another problem was the occurrence of rust. The metal we would have liked to use was stainless steel to avoid the rusting but because of the amount of days that had gone by, rust would have started to occur. Restricted enzymes were going to be used to help speed up the process of getting the DNA across the needed distance so we could see it. If we did have the resources that we wanted, the murderer’s DNA would have matched up with Friar Laurence’s DNA. Paragraph Two: In my groups hypothesis we predicted that the murderer of Romeo and Juliet was Friar Laurence, and we were correct. For the lab, we did not have the materials and resources we needed to extract the DNA and match it to anyone. Our group was not able to come up with any data, or record anything. I think if we had the materials we needed, and knew we needed them beforehand, we would have come up with conclusive results.

                                                3 Takeaways from Ted talk- PTSD
  Three takeaways from the ted talk or things i was surprised about was was 1. That crime rates, suicide rates, and death rates went down after 9/11. I didn't know that vets get PTSD after they come home, and not during the war. People who fight for the US and go to the war, and come back to a civilized country, it is more likely for them to get PTSD rather than someone going back to an uncivilized country.

                                                             Cauliflower Lab
We were put into groups during a science rotation, given a cauliflower to use as a brain. We defined all the parts of the brain, labeled them, and brought it up to our teacher. Our teacher took our brain and said this person has been in a major car accident where she hit a wall. A chunk of the frontal part of the brain was cut off along with a part of the back because of whiplash. See below for her full story.




                                                       Brain Anatomy Narrative 

Finally, the doctor returns. I’ve been awaiting the news of what happened to her. All we know is she has been in a serious car crash, but that is the limit of our knowledge. The doctor starts to explain what has happened. He says that the crashed cause the patient to hit their head on the steering wheel, and when her head whipped back, she fractured the front and back of her skull, and took off a good part of the front and the back of her brain..

    The doctor said that what happened could be something called contrecoup. A contrecoup is when the patient in this instant, hits the front of their skull, and the back part of their skull shatters. The doctor believes this happened, but they will need more information before they will know for sure.

    Some changes that will occur because of the accident is memories could be lost, can change how she will react to things, and it will also make it harder to connect words with meanings, All of these changes will occur because of frontal lobes, in the front part of her brain, right under her forehead. The last set of changes that could happen is unable to distinguish left from right, difficulties reading, drawing, doing math, and problems with hand eye coordination.

    All of these symptoms the doctor named really scared me, my friend will never be the same. When she wakes up, she could not even know who i am, and i will have to re-teach her things like how to be aware of herself, and to do everyday things that we always do, which will be now hard for her to execute.

How long does food stay in the frozen, without getting freezer burn or going bad?
Food can stay frozen for as long as your freezer is plugged in and functioning normally.
http://www.thekitchn.com/do-you-know-how-long-foods-will-keep-in-the-freezer-194281

Are canned foods good to eat indefinitely?
As long as the canned food is stored in a cool, dry place, it can be good for up to a year.
http://nchfp.uga.edu/questions/FAQ_canning.html#5

What is the most genetically modified crop?
The most genetically modified crop is corn. Nearly all of corn is genetically modified, 88% to be exact.
http://www.huffingtonpost.com/margie-kelly/genetically-modified-food_b_2039455.html

Are there any differences between the three types of corn, if so, what?
There are very little differences between the corns, is that the canned corn, (del monte) has water added to it.

The only ingredient out of the three that states they are infact GMO free, is the Del Monte canned corn.

How does freezing foods change the quality?
Freezing will not improve inferior foods, but in some cases, water in foods produce ice crystals which will break down the cell structure in some foods. Although, if foods are stored too long, or at a bad temperature, then it can cause the food to go bad.

                                                           Making Agar
 First, we read the instructions and crushed 4 agar tablets to fill our 8 petri dishes, then we put the crushed agar into water. We put the water on a hot plate, of 500 degrees. My group and I put on gloves, because of the heat, and continuously stirred the agar over the water, for about 1 minute, and after 30 seconds of it cooling, we poured it into the petri dishes, and lastly, stored them in the incubator.

                                                        China Study Teach-Back

Today we learned all about how having an unhealthy diet can affect your lifespan, how you can become obese which can lead to many other problems, how it can cause cancer, and how a healthy whole food, plant based diet can help that. This is all the information I gathered from the teachbacks.

                                                           

                                                                 CHAPTER 6

In american 1 in 3 people are VERY obese

In china, levels of obesity are very low, along with diabetes

The good key to a healthy weight loss is a whole foods diet

Getting diets up is the best way to lose weight

America spends 70 billion dollars on health care just reducing obesity

30-40 billion dollars just trying to reduce weight gain

In china, more people eat a whole food plant based diet

The chinese have an all around healthier diet and population because of their whole food, and plant based diet, while america spends money on pills and surgeries trying to avoid weight gain.

Over 15 percent of america's youth is overweight and obese

                                                            

                                                               CHAPTER 7

Insulin is a hormone that moves sugar through your body and produces energy

Diabeties begins with dysfunctional glucose metabolism (process colapses)

Type 1 Diabeties

You are born with it

Illness you obtain

More glucose, and less insulin which means less insulin is going in to help your organs, which means you have less energy

Type 2 Diabeties

Insulin does not work in all, and it is resistant

70% higher blood pressure

Some people dont even know they have diabeties

Symptoms- Always thirsty, hunger, blurry vision, low energy

A diet higher in carbs and lower in animal fat will result in less of a risk of diabeties, or can reverse the process

Immune system is very complex

Autoimmune disease is when your immune system stops working and takes cells and destroys them, and 1 in 4 people in america are diagnosed with this disease

Women are more likely to obtain this disease than men

1 in 30 people are diagnosed a year

11.3 greater change to get type 1 diabetes if you are not given breast milk as a child

Dairy products in your diet as a young age, can affect diseases like diabetes

NS is a disease that can make you lose the ability to walk, or to see, that destroys surrounding tissues and sends electric shocks to your body

NS is caused by dairy product intake, jeans, magnetic fields, and your diet.

                                                  

                                                          CHAPTER 10

A plant based diet is better because it prevents a broad range of diseases. And to be honest people can hear something and agree with it but they don’t actually change.

Just by changing your diet, you can avoid a kidney stone



                                                The Mushroom King

Today, the mushroom king came into the class and gave us lots of new information about mushrooms. The mushroom king had been around mushrooms his entire life, and it was something he was always very passionate about, therefore he started a business, and now many restraunts use the mushrooms he grows. He brought all different types of mushrooms in with him, and even made the class some mushrooms, just like the way he would make it. He made sure that he didn't over power the mushrooms with spices, seasonings, and herbs, because he wanted to keep the taste of mushrooms and enrich it.He  finished the mushrooms, and let us all taste them. I learned a lot more about mushrooms, like how many different kinds of mushrooms there are, how different kinds of mushrooms come in different seasons, and how mushrooms can save oil spills, and feed off of bad things from the earth to make something edible and delicious.

                                                       Cellular Respiration

In the cellular respiration lab this week, we made brownies to show how the process of cellular respiration works, in a different way. The three stages of creating ATP are glycolysis, the krebb cycle, and the electron transport chain, also known as ETC. The first step in the lab was to measure and look at how much sugar we should consume in a day, versus how much we actually do consume, then lastly, compared to one gram of sugar. The difference was huge. Next, we started the glycolysis process. This is when the sugar molecule gains 2 ATP to help break down the molecule, and created 2 ATP. Next, comes the mitochondria where the krebb cycle takes place. The process gets 2 ATP to help move the process along, and gains 2 ATP at the end too, along with other molecules like Co2 an H+. Lastly, the electron transport chain, also known as ETC. This is the last step, where around 32 ATP is produced. (The ATP was the brownies in the lab)

                                                                      Iron Chef Lab

For my iron chef lab, my group chose corn. We received corn in three different states. Frozen, canned, and an ear of corn. 

                                      

                                                     The Soil Lab

     We did a lab called the "Soil Lab". The soil lab was meant to help us be able to see different kinds of soil, and record the differences. We recorded differences such as how well the soil absorbed water, observed the grain size of the soil, and the density. Lastly, we had the chance to measure the soils pH, using tools i have never used before.

                                               Making Poop Lab
                         This week we participated in a lab called the making poop lab
For the lab, each group was responsible for one section of the digestive system. My group was responsible for the first part of the digestive system. The first part of the digestive system is the mouth. The mouths job is to use the canine teeth and the molars to crush and break down the food. Enzymes in your saliva also help break down the food. After the mouth, the food moves onto the esophagus. The esophagus is a muscular tube that connects with the throat and the stomach. Then the esophagus leads to the stomach. The stomach continues the digestive process by adding chemicals and acids to continue breaking down the food. Next, comes the small intestine, where 90% of the absorption happens, along with more digestion.

 After the small intestine, comes the large intestine. The large intestine absorbs the remaining water, stores the remaining waste material, and finishes some of the last steps to the digestive process. Lastly, the remaining toxins and waste that your body does not need, produces poop.
