Photosynthesis Experiment : Carbon Dioxide

Photosynthesis Experiment

“ Proving that the plants needs Carbon Dioxide”

Materials:

-       Bromothymol Blue

-       3 test tubes

-       Test tube rack

-       Pondweed

-       Straw

Hypothesis

The result of this experiment is the change of color in the Bromothymol Blue. If the color of the solution changes to dark green or dark blue, it shows that the pondweed has absorbed carbon dioxide, which proves that the plant needs carbon dioxide in photosynthesis. If the color of the solution doesn’t change, that means the plants doesn’t absorbed carbon dioxide.

Procedure:

1.     Cut the pondweed into 3 small parts, all on similar lengths

2.     Set aside the pondweed and prepare the Bromothymol Blue

3.     Fill ¼ of the test tube with Bromothymol blue and add water until it fulfill half of the test tube

4.     Put the straw inside the test tube and slowly blows from your mouth, this will trigger the change of color to yellow green. Be very careful to not inhale the solution

5.     Afterwards, take out the straw and slowly drop the pondweed to the solution

6.     Put the three test tubes on the test tube rack and see the color changes.

Noted that the test tubes are put in the same condition, in this case under the sun or the light.

Results and Comparison

1. The solution when it was first put bromothymol blue and water with the pondweed. Solution still has the carbon monoxide

 2. After being left for 2 days, in the shaded but still can obtained sunlight

3. Comparison between the first solution ( when it still has the carbon dioxide) and the second solution ( when the plant has already absorb the carbon dioxide in the solution)

Observed Plants in My School

Hey guys! so today, I'm going to discuss to you about what I observed in my school yard. There are 3 plants and they have their own specialties. The are also located in a different way.

Plant 1

Physical Appearances : has the mixture color of pure green, light green and white. It has a very smooth space and has an elliptical shape. It also has a smooth edge. the leave has a length of approx. 10- 15 cm wide.

Location: It was located in a pot, with a wet soil. It also placed under a big tree.  Even so, the tree can still have an access to sunlight.

Other Species: There are some insects such as ants that are spotted around the plants.

Plant 2
Physical Appearances : has the color of light green. It has a very smooth space and has a heart shape. It also has a smooth edge. the leave has a length of approx. 5- 8 cm wide.

Location: It was located in a fence. Its located in a wet-dry soil. It didn't get much sun light like the first plant. The tree is growing around the fence

Other Species: There are some insects such as ants that are spotted around the plants.

Genetically Transmitted Disease : Marfan Syndrome

So, the genetically transmitted disease that I found has the name of Marfan Syndrome. It is a genetic disorder in the connective part tissues. There is a change on one of the pair in Chromosome number 15, which creates Fibrillin. Our body is connected by tissues and it is made of a protein. Fibrilin genes makes a protein name Fibrillin-1. The disorder happen when it improves or create more of the fibrillin-1 to TBF-Beta.Then, there will be problems everywhere such as heart, blood vessels, bones, joints, eyes and lungs. It has the total affect on the human body, but also the human mind for they are stress of being objected in society. People who has Marfan Syndrome usually has a trait of long arms and legs,scoliosis, flat feet and has chest that sinks in or humps out. The condition of this syndrome to be pass down is by a Autosomal Dominant pattern. This syndrome also usual happen to those family who never has the history of having these syndrome. From the data I searched,both male and female can be affected and be carriers. Abraham Lincoln is one of the famous people who experienced the Marfan Syndrome. Other famous people that had this syndrome was the famous pianist, Sergei Rachmaninov , as well as the famous sportsman, Michael Phelps. Even having this disease, these people still are recognized around the world and achieved so many things. 

Independent Study : Marie Curie

Marie Curie, Born in November 7 1867. She is a Nobel Price winner in the year 1911 for her discovery of Radium, Polonium, Isolating Radium, and the study of Radium Compound. She also received the Nobel Price for founding Radioactivity on the year 1903. Her dedication to science was out-standing. When she gave birth to her first daughter, Irene, she didn't stop researching about radioactivity. Then when her husband died, in her grief she still teaches at Sorbonne. As a women she also achieved many things. She is the first women who won the Nobel Price twice and in two majors , Physics and Chemistry. She is also the first women in France to become a professor and the first person who improved the use of X-Rays.Marie Curie as a mother  has achieved well, for her first daughter, following her foot-steps and received a Nobel Price in the year 1935 with her husband for the new founding of the radioactive elements. Then, at her final days, she shows her devotion to science for she still carries Radium in a test tube inside her lab coat pocket. But all of those experiment on Radiation has a great impact on her body. She past away on July 4 1934, because of Aplastic Anemia.

Science in Everyday Life

For today's blog I'm going to do 5 things on my list and explain to you about.
1. Watch a spider spins its web. What techniques does it use to achieve the final shape.

a spider has a silk glands and it is the materials that made the web itself. First a spider will produce the silk. After it has been produced the spider will make the pattern of the web from the inside to the out. After that, a spider will use it's arms and legs to help those pattern connect to each other from the outer part to the inside part.

2. Watch the sky at sunset. Which colors do you see? Which are the closest to the earth and which are the highest in the sky? How long does it take the sun to disappear below the horizon?

In the picture the colors are white, yellow, orange, purple-ish blue. The white, yellow and orange are the closest to earth, while the purple and blue color is the highest in the sky. I took about 1 hour util the sun disappear below the horizon. Looking at the time period from 5 pm - 6 pm.

3. Play a musical instrument. How does that instrument create sound? how can you change the sound it makes?

The instrument that I chose is the piano. When someone is pressing the tuts or the white blocks that existed in the piano, It will make a sound. This happens because the tuts inside are connected with a string, when we press those tuts, the tuts will hit the string . Vibration happens and created sound. You can change the sound by pressing different tuts and playing different style of chords.

4. Create heat in three different ways. Describe each process and indicate which produces the most heat with the least effort.

 The three easiest way to create heat is to rub your hands together, hug another person, and use a sweater or jacket. when you rub your hands together, it gives friction. The friction combined with the with the body heat, creates a warm situation. Same thing when your hugging another person. When two bodies stick together, both of them will give out body heat, which makes it warm. The last is using a sweater. by using a sweater, your body is trap, thus gives us the heat. this makes the easing way to create heat because you don't need friction and you don't need someone else.

5. Rub a balloon ( or a ruler in my case) on your hair in the dark ( since its a ruler I didn't do it in the dark) to watch a static electricity. Can you make the balloon ( ruler) stick to anything after it has been rub.

The ruler did create a static electricity. I rub it  on my hair and then put it on top of a piece of small paper. Then it suddenly stick to the ruler. This happens because there is an exchange in the electrons.
