Week 1

An example to illustrate how I normally utilize scientific method in my daily life is while a fix a cup of coffee every day.  This is something that  I  normally  do each and every  day since I  enjoy  coffee  a lot.

Making Observation

I  get home and  head to the  kitchen for coffee as usual from the coffee  maker  machine, set  an empty coffee  cup under  the machine’s nozzle pressing  the button  for a dispense  of  coffee.  I can see the coffee in front of me.  Immediately I begin to  ask myself  whether  the  coffee might  be too hot  to  drink at that  moment.

Hypothesis

From all my prior experiences with coffee, it is more likely that the coffee is hot based on what I am used to.  Because  I  had  just  poured the coffee  and  had no time  to sit  out I assume  that it is too  hot  to drink.  My hypothesis in the case is that the coffee is too hot to be drunk.

Experiment

I divide the coffee into two halves.  I move  my  hand in a gradual  manner  to the  initial  cap  to  obtain the  idea of its  warmth.  It is my belief that  if the  coffee is too  hot  it should  make the  cup  warm then  if the cup is not that  warm this means  that  it is ready  to be drunk.

Data Analysis

Upon  conducting my experiment  and allowing the other  half  to  cool I  realized  that the  cup  is not  as  warm as usual and therefore the  coffee is not  too hot  as  expected.  The coffee was therefore; ready to drink while the one that cooled was not favorable.

Conclusion

The coffee was not too hot to drink.  My hypothesis in the case was wrong.

Dependent Variable

My response to the warm and cooled coffee

Independent Variable

Dividing the coffee to cool

Control Variable

The amount of time utilized to wait for the coffee to cool

Response

The example on the driver’s schedule being influenced by weather had a very specific hypothesis.  However, the conclusion did not support the hypothesis directly.  Independent, control as well as dependent variables should also have been incorporated for accuracy and reliability.  In addition  weather is  more of a seasonal issue  rather  than a daily  one  which makes  it  hard  to  test  the  experiment  in the long term. The experiment  can be  developed  by the utilization  of a more  direct  example  that can be tested every day  without  the  challenges  of seasonality.

Week 2

Hamburger parties are my  favorite  they are  made  with  grounded  beef  and  comes in different  kinds and  sizes.  They hold much protein as well as fat that is contained in the red meat. Carbohydrates are not excluded as it is contained in the baked bread but it is usually in low content.  It is therefore made up of calories, minerals, organic, regular, vitamins, proteins as well as fat.

Hypothesis

Hamburger lacks a nutritional balance as it offers more proteins as compared to vitamins and carbohydrates.

Based on research hamburger contains proteins, carbohydrates, calories and fats which are 6, 13, 11 and 14 percent respectively (Odom, 2015).  The diet lacks vitamins as an essential molecule that is highly necessitated in living.  The research supported  by hypothesis  even though not directly by stating that  hamburger  does not  provide  a balanced  diet  as some  molecules  are high  than others.  Despite the fact that proteins are required in the creation and refurbish of tissues a balance of lipids, carbohydrates and proteins is a necessity (Odom, 2015).

Response

From the post on the  Dog’s  taste the  discussion lacked  a detailed research on  the  molecular  composition  of the  food  and its benefits.  The hypothesis was however, well developed in support of the experiment.  The  example and the experiment should be  equipped and developed  more by ensuring that  the content of the foods’ nutrition is  offered   with  that company  of a thorough  research  to support  the  thesis.

Week 3

Lynn Margulis made the proposition that the comparisons amid organelles and prokaryotes in combination with their fossil record appearance can best be detailed by endo-symbiosis theory (Fossil, n.d). The proposition was aimed at explaining the eukaryotic cells evolution to demonstrate that Organelles were fully different from the bacteria types that separated in the evolution (Fossil, n.d). Mitochondria are amongst the numerous organelles kinds that are established in all eukaryotes cells. Generally they are accounted to have developed from Proteobacteria via the Endo-symbiosis procedure (Fossil, n.d). On the  other hand  Chloroplasts  are among the  distinct  organelles  kinds  in the cells plant which  developed  from  cyanobacteria via endo-symbiosis (Fossil, n.d).

Response

The most interesting post that I choose to respond to is that of diapers chemical composition. The absorption  composition  is assisted  by  absorbent  polymer  which holds the  incredible  capability  of absorbing  inside  all the designed  layers this is  developed  from  petroleum and contains  strong chemical that  are  of assistance  in  its  accomplishments.
