Green Human Project

This is the Green human project that I made and my idea should really happen!!!!

Second Quarter Self analysis Standard 8

Remebering: What I did in Biology was:

1. The lab I created:)
2. My Microscope Test!
3. Cystic Fibrosis
4. The Kid that had CF
5. PKU Webquest
6. Cells project
7. Enzyme Action
8. Photosynthesis Dry Lab
9. Green Human Project

What is important about it:

Each blog was really need to write and to engage myself into something new. My favorites would be learning about the  microscope, PKU, and the Enzyme Lab. Just these blogs gave a new insight and a better view of Biology.

Applying:

I do happen to apply Biology in everyday life because I have a Biology class but in the future I'm looking into the medical field but Im not sure if I want to be a dental hygienist or a OB nurse. 

Evaluating:

This 2nd quarter I think I did well with my blogs they became or in-depth and detailed. Some even had really good references and videos to show how I understand the works of Biology. I would give my self an A for effort.

Creating:

From the last quarter I have reached my goal of putting some more visual effects into blogs and also using for technology in this class. Also I have reached my goal of having deeper explanations of what we are studying. This next quarter I would like to get better at writing blogs so I could get more 4's. Getting 4's on everything is going to be my goal. 

Photosynthesis Dry Lab

Photosynthesis Dry Lab

In this “dry lab” you will be working backwards from what you would normally do in a lab situation. In this case, you will be given a set of observations that were made in a lab and you will be asked to reconstruct the procedure that could have generated this data. You will also be given a set of facts that you will use to explain this set of observations in the analysis and conclusions section of your lab write-up. As you create the procedure for this lab, please remember all the rules that you have been learning about good experimental design.

Your lab report begins below. Fill in the missing sections of the lab report using the observations and facts given. You may assume that you have access to as many test tubes, snails, Elodea plants, light sources, dark places, and as much pond water and BTB as you need.

Make your own copy of this Google Doc and edit the lab report that begins here:

My Most Awesomest Photosynthesis Lab Report

by

Kelsey Nolte

Purpose: To understand the ways of photosynthesis.

Background Facts:

• Carbon dioxide in water produces carbonic acid.
• Bromothymol Blue (BTB) is a blue-green liquid which changes to a yellow color in acid and back to blue-green when returned to a neutral pH.
• Carbon dioxide plus water yields sugar and oxygen when chlorophyll and sunlight are present.
• Animals respire.
• Green plants photosynthesize in the light and respire all the time.
• Sugar plus oxygen yields carbon dioxide plus water and energy.

Hypothesis:
My hypothesis is that if i was to put a snail into BTB the water will turn yellow because the snail is respiring. Also if we were to put  Elodea into BTB the water will still be blue-green because there is no mix of of carbon dioxide to made carbonic acid.

Materials:
Test tubes, Snails, Elodea plants, Light sources, A dark place, Abundance of pond water and BTB



Procedure:

1. Fill the 5 test tubes with 100 mL of water then add 5 mL of BTB
2. Label the first test tube 1, the sencond 2, the third 3, and the forth 4, and the fith 5
3. Leave test tube 1 untouched
4. Observe and record what happenes
5. Place a snail in test tube 2
6. Oberve and record what happens
7. Place a Elodea plant into testtube 3 and observe what happens
8. In testtube 4 place a snail and the Elodea plant in the dark for 3 hours
9. Observe and record what happenes
10. In test tube 5 place a snail an the Elodea plant in the light for 3 hours
11. Observe and record what happenes
    
    Observations:
    
12. Water plus bromothymol blue is blue-green.
13. Water plus bromothymol blue plus an aquarium snail turns yellow.
14. Water plus bromothymol blue plus Elodea (an aquarium plant) is blue-green in light.
15. Water plus bromothymol blue plus a snail plus Elodea is blue-green in light and yellow when left in the dark for three hours.

Analysis and Conclusions:

1. Water plus bromothymol blue is blue-green because...

This is because the BTB diffused into the water turning it blue-green.

2. Water plus bromothymol blue plus an aquarium snail turns yellow because...

There is oxygen or the snail is respiring (CO2) which turn into carbonic acid when mixed with water. Which changes the pH of the BTB causing the water to turn yellow.

3. Water plus bromothymol blue plus Elodea (an aquarium plant) is blue-green in light because...

This only gives off oxygen and sugar and it is not changing the BTB color because there is no CO2 given off.

4. Water plus bromothymol blue plus a snail plus Elodea is blue-green in light and yellow when left in the dark for three hours...

This is because when the plant in the dark the plant is not photosynthesizing. When there is no sun the plant will not get energy and will give off CO2 (carbon) and there will be carbonic acid to change the pH that changes  the water yellow. So the plant can have the process of photosynthesis if there is sunlight that will cause the water to change color.

Enzyme Action

This blog is about enzymes the effect of enzyme concentration, the enzyme effect with temperature,  and lastly the effect of pH of the enzyme. An enzyme is any of various proteins, as pepsin, originating from living cells andcapable of producing certain chemical changes in organic substancesby catalytic action, as in digestion (this is just the book definition of enzyme). This was a lab with other group members to examine the ways of enzymes. The presentation gives a good explanation of what happened in this lab. Something to think about before you look at the presentation is what do you think will happen to the enzyme if it is placed in a tube of boiling hot water and freezing cold water.

Cells project

Cells project! This project is about parts of the cell and it also has a youtube video explaining the diffrences of the pant and animal cell.

PKU Webquest

PHENYLKETONURIA: A METABOLIC DISORDER

Metabolic disorders are genetic diseases that affect the body's ability to perform its normal chemical reactions. Many metabolic disorders result from enzyme defects. Recall that a metabolic pathway is a stepwise sequence of enzyme-mediated reactions. If one enzyme in a metabolic pathway is defective, that enzyme's substrate may accumulate and the pathway may not be completed. This may result in a buildup of harmful substances or a shortage of required molecules.

Activity

In this exercise, you will use the Web links below to gather information about the metabolic disorder phenylketonuria (PKU). Use what you learn to answer the questions at the bottom of the page.

Questions

1. What enzyme is most commonly defective in people with phenylketonuria?
The most common defective enzyme is called phenylalanine hydroxylase which is needed to break down essential amino acid callednphenylalanine into a different amino acid called tyrosine.

2. What reaction does this enzyme catalyze? (What is the substrate and what product is produced?) This reaction causes a build up of high body levels called hyperphenylalaninaemia  which can damage the brain.
3. Describe the symptoms of phenylketonuria.
The symptoms of phenylketonuria vary from mild to very serious:
Seizures, delayed development, behavioral problems, and psychiatric disorders are also common.
Children with classic PKU tend to have lighter skin and hair than unaffected family members and are also likely to have skin disorders such as eczema.
Some cases aslo cause brain damage to the child.

4. What causes the symptoms of PKU, the lack of a substance or the buildup of one?
Phenylalanine is found in proteins of the food that we eat, and reacts badly with the PKU because the hindered enzyme is one of a metabolic nature.


5. How common is phenylketonuria? How is it treated?
PKU is not very common. Rates in Asian and Caucasians are rare but come up more in Irish and Turkish heritage families. It is treatable and is treated by a low protein diet that is carried out throughout the patient’s lifetime.

The Kid that had CF

After watching the video I really think that the school was being really unfair with Coleman. He shouldn't be segregated for having that disease. You can see Coleman is really upset with what these school did. He is just a young boy who is trying t fit into a new school. I moved to a new school and I know how hard it was to make friends even when I didn't have a disease. For the school to say he can't go to school there is wrong. In the video when the Doctor and Layer talked about how wrong the school was on both sides and how the child can't infect anybody if he is not in contact with somebody. We were all thought to cover our mouth when we cough and to sneeze into a kleenex or to sneeze into our arm/ shirt. This video shows how crewel people are to others because of a LIFE THREATENING  DISEASE. Everyone should watch this video and learn how bad CF really is and how it could take such a precious life with it.

Here is the video to watch.  Please comment on what you think of this?
