14. Brainstorm and write at least 3 potential challenges or important points to consider when conducting the described
Afina-wow [57]

When conducting an experiment, there are different aspects to consider, such as the question that drives to the reseach, the hypothesis, theoretical framework, variables involved -independent, dependent, and controll-, methodology, study groups, data analisys, among others.    

In the exposed example, Pincky is lacking <em>theoretical framework, d</em><em>efining which are the </em><em>study groups, methodology </em><em>to collect data</em><em>, </em><em>and a description of </em><em>data analysis</em>.

---------------------

The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: <em>reproducibility, </em><em>which is the capability of reproducing the experiment in any other place by any researcher</em>, and <em>refutability, </em><em>which is the susceptibility to be refused.</em>

When conducting an experiment, you need to consider,

• Definition and problem statement. The question for which there is not an answer yet.

• Hypothesis formulation. A hypothesis is a scientific conjecture, not verified, that requires corroboration.

• Data collection and analysis. This step involves testing the observations.

• Results

• Verification of hypothesis. This step involves the deriving of the working hypothesis.

• Discussion and Conclusion.

Previous knowledge about the study object is always required for a better understandig.  A question the investigator wants to answer. The main goal of the study, which is basically what the investigator wants to find out. The researcher makes a hypothesis to predict what is going to happen. The experiment is to be performed to answer the question. The conclusions through which the hypothesis might be rejected or accepted.

--------------

So in this experiment there must be,

Theoretical framework, such as information about the species, life stage at which they begin chirping, about external factors that might affect it or benefit it, and etcetera.

The goal: To know how temperature affects cricket´s chirping

Hypothesis: Crickets chirp less frequently under cold temperature than under warm temperature.

Variables: Temperature → Independent

                 Chirp frequency → Dependent

                 Water and food supply, light exposure, refuge → Controlled

Study groups: group of crickets exposed to a warmer temperature

                        group of crickets exposed to a colder temperature

Methodology: Individuals analyzed should be in the same development stage, or at least be sexually mature. Two groups of 10 individuals each should be placed under the same conditions, excepting for temperature. One of the groups should be exposed to warmer temperatures and the other one to lower temperatures. Chirps should be recorded for a week.

Data analysis: Using the chirps records, the frequency can be measured for each group. Results should be compared using different statistical analyses.

Results: Results should be clearly exposed, using texts, charts, and graphs.

Discussion and Conclusion: Hypothesis acceptance or rejection. Discussion about the expected results against the observed ones.

5. Create a script of dialogue that could occur between a
harkovskaia [24]

Answer:

Pauline and David are talking about the use of resources in a sustainable manner so that both humans and living organisms can co-exist and enjoy the benefits of nature. Pauline is a conservationist whereas David lives in a biodiversity hot spot. The conversation starts when David and Pauline meet in an ecology conference. Pauline is standing in front of poster talking about conservation of environment and wildlife. David pass by and see that the topic is quite interesting.

David: Hey, I like your topic of presentation.

Pauline: Thank you! are you also a conservationist?

David: I wish I could be but my job nature doesn't allow me to work in this area. However, I truely care about the wildlife which are being threatened in my neighbourhood...

Pauline: Oh, I am sorry to hear that... Where do you live?

David: I live between the city and forest, which is being affected by humans interventions. I see everyday a lot of animals dying on roads because they are forced to migrate because of forest cutting, however, while doing so, they are killed by human's actions.

Pauline: I absoultely hate this behavior of humans. I think human's should understand the importance of other organisms in biogeochemical cycles otherwise our generations are going to pay a lot for this.

David: Definitely, I wish we could reverse such decisions but again, they are not easy. With growing human's populations, we need to adjust everything accordingly.

Pauline: You are right. But we can develop strategies where both humans and animals can live in hormony, such as development of ecological corridors in a forest if we want to make a road, could help these creatures to survive well.

David: I cannot agree more. I hope such things are encouraged in near future. But I really liked your idea and would like to discusss sometime later.

Pauline: Sure, you can visit me anytime in my office at XYZ location.

David: Thank you, see you than!

Pauline: See you!
