Biology Experiment: Carbon Dioxide

Photosynthesis Experiment

“ Proving that the plants needs Carbon Dioxide”

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 from the previous color, that means the plants doesn’t absorbed carbon dioxide.

Materials:

-       - Bromothymol Blue

-       - 3 test tubes

-       - Test tube rack

-       - Pondweed

-       - Straw

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.

Result: 

At the end of the experiment, there was changes of color in different test tube. Some needs carbon dioxide as its color changes and some didn't need carbon dioxide as the color stay the same.

 The first test tube in this picture still contains carbon monoxide and was put down for 2 days to see the changes of color.

Before

After

 After 2 days, the color changes into darker green which proves that the plant needs carbon dioxide as it's already been absorbed

The result from the 3 test tubes after 2 days: 

Before                                                           ->                                 After

Genetically Transmitted Disease

  The name of the genetically transmitted disease that i've chosen is called the Down Syndrome. This syndrome can affect both gender because its all the same and this happens if there is an extra copy in 21st chromosome. The famous artist that suffer from this disease are: Laz-D, Jamie Brewer, and Chris Burke. The symptoms that can be founded in Down Syndrome can't be identified during pregnancy in your children but after the birth of your children, the symptoms founded if your son has a Down syndrome if your children has:

• Flat facial features
• Small head and ears
• Short neck
• Bulging tongue
• Eyes that slant upwards
• Oddly shaped ears
• Poor muscle tone

Social action can also help identify if your children has suffered from Down syndrome which are:

• Impulsive behavior
• Poor judgement
• Short attention span
• Slow learning abilities

  This syndrome can cause your son/daughter to have multiples effects which can cause the person to have:

• Thyroid disease
• Obesity
• Skeletal problem
• Visual Problem 
• Seizure
• Hearing loss

Experiment in Everyday Life:

Experiment in Everyday Life:

Experiment 1:

Objective: Leave some old bread out till it has mold growing on it and describe what you see happening

Materials:

• Bread

Procedure:

1. Get a bread that you haven't ate for a long time
2. Put in on a plate and wait for the result

Result: The molded bread start to spread from a small part to a big part which happens due to the fungus spreading to the whole bread.

Experiment 2


Objective: Can you make the ruler stick to anything after it has been rub?

Materials:

• Ruler
• Paper
• Scissors

Procedure: 

1. First, you cut the paper into small pieces using scissors
2. Next, you rub the ruler on your hair for some time.
3. After rubbing it on your hair, you can try to attract the small pieces of paper that you cut earlier to the ruler.

Result: We can see that after the ruler is being rubbed on hair it can attract small pieces of paper to the ruler. The thing to explain this is because of the static electricity that leads to the transfer of electron making the paper attracted to the ruler

Experiment 3

Objective: How does that instrument create music? How can you change the sound it makes?

Materials: 

• A Guitar

Procedure:

1. Try to pull the string without touch the fret
2. Then try to strum while holding some of the fret

Result: We know that the guitar produces sound. The guitar produces sound from the vibration of the strings because the strings were strummed and this causes them to vibrate and produces sound. When it touches the fret, it sounded different because the vibration is much more little than the one without touching the fret

Experiment 4

Objective: How does the bicycle work and move?

Materials:

• A Bicycle

Procedure:

1. Ride the bicycle 
2. Try to move the pedals slowly like your trying to move the bicycle
3. Observe the bicycle especially the gears 

Result: As you can see, the gears near the pedal moves and it connects to the gear in the back wheel. These conclude that it needs power (energy) from the rider to move the pedal so it can give the command to let the rear wheel move.

Experiment 5:

Objective: Spin both hard-boiled egg and a raw egg

Materials: 

• 2 Eggs
• A Pot
• Boiled Water

Process: 

1. You boil the egg until the shell became much more harder
2. You spin both eggs at the same time
3. You observe the result

Result: So from the result, the hard-boiled egg stops first rather than the raw egg. It happens because there was heat in the shell so it will be much harder for the hard boiled egg to spin.

Example of Gene Mutation

Example of Gene Mutation:

1. Progeria

It is a mutation where the victim has a disease called
accelerated aging. It leads to death in a very short time since you're age is accelerating faster.







2. Hypertrichosis

It is a mutation where the victim has a hairy disease where it will grow on the shoulder, face and ears. This mutation is often called the "Werewolf Syndrome".




3. Severe Combined Immunodeficiency Disorder (SCID)

It is a mutation where the victim doesn't have a effective immune system and has to spend their life in a plastic bubble.
