Scientific Method

Scientific Method -A process of conducting experiments to test if a hypothesis is true or false. 

The scientific method is generally performed with 6 steps:

1) Purpose/Question- Ask a question.

2)Research- Conduct background research. Interview experts on a topic. The more you know about a subject, the easier it will be to conduct your investigation.

3) Hypothesis - Propose a hypothesis. Usually, a hypothesis is written in terms of cause and effect.

4) Experiment- Design and perform an experiment to test your hypothesis. An experiment has an independent and dependent variable.

5) Data/Analysis - Record observations and analyze the meaning of the data. Often, you'll prepare a table or graph of the data. Once you have the data, you may need to perform a mathematical analysis to support or refute your hypothesis.

6) Conclusion- Conclude whether to accept or reject your hypothesis. There is no right or wrong outcome to an experiment. The results may be compiled into a lab report or formally submitted as a paper.


In an experiment there are Three Variables:

1-Controlled Variables: You can have as many controlled variables as you like. These are parts of the experiment that you try to keep constant throughout an experiment so that they won't interfere with your test. Writing down controlled variables is a good idea because it helps make your experiment reproducible, which is important in science! If you have trouble duplicating results from one experiment to another, there may be a controlled variable that you missed.

2-Independent Variable: This is the variable you control.

3-Dependent Variable: This is the variable you measure. It is called the dependent variable because it depends on the independent variable.

Prototype Final

Link to Colin’s Final Prototype on Construct 3: https://www.construct.net/en/free-online-games/colin-hanrahans-final-42528/play  ______________________________________________________ Here is the link to my final Prototype in Construct 3. It was very informative and exciting to research Media Dependency Theory as a Framework to prove the thesis in how women above the age of 30 have increased mental stress when watching cable news due to its fear-inducing segments.

Fear Appeal Definitions

Below I compiled all of my sources and made a list of quotes defining the purposes and uses for 'Fear Appeal'. My intentions are to list out all of my findings and compile them into my narrative for the first segment Fear Appeal Definitions: 1- “Fear Appeal persuades people to feel that they are assuming a risk if they do or do not purchase a certain product. The idea is that if consumers don’t use the product you are advertising, you make them feel like there may be undesirable consequences as a result.”(Newbold, 2017) 2- “They found fear appeals to be effective, especially when they contained recommendations for one-time only (versus repeated) behaviors and if the targeted audience included a larger percentage of women. They also confirmed prior findings that fear appeals are effective when they describe how to avoid the threat (e.g., get the vaccine, use a condom).” (Tannenbaul et al., 2015) 3- "According to fear appeal theories, a fear appeal is defined as a message th...
