PartI: Media Relevancy

Readeach statement.

Writea 100-word summary explaining how the chosen media piece supports thestatement. Include reference citations.

  1. Find a media piece—article, video, presentation, song, or other—that recognizes the fundamental concepts of chemistry in biology. Include the link or reference citation for the piece and describe how it helped you better understand how fundamental concepts of chemistry affect biology.

  1. Find a media piece—article, video, presentation, song, or other—that describes the energy metabolism of cells. Include the link or reference citation for the piece and describe how it helped you better understand the energy metabolism of cells.

  1. Find a media piece—article, video, presentation, song, or other—that compares the structures and functions of different cell types. Include the link or reference citation for the piece and describe how it helped you better compare structures and functions of different cell types.

  1. Find a media piece—article, video, presentation, song, or other—related to the scientific method, creating hypotheses, or designing experiments. Include the link or reference citation for the piece and describe how it helped you better understand how the scientific method is used to create hypotheses and experiments.

PartII: Applying Science to Everyday Life

Recently,Earl attended a picnic at his daughter’s school. The picnic was apotluck, and the food was served outdoors. Contributions includedhamburgers, hot dogs, baked beans, potato chips, potato salad,coleslaw, apple pie, and vanilla ice cream. Within 24 hours of thepicnic, several attendees developed symptoms of food poisoning. Ofthe 50 people who attended the picnic, only 30 people became ill.Every person at the picnic ate something, but not every person had anopportunity to sample each item. Earl noticed that the potato saladhe started to eat was warm. He also noticed that his hamburger wassomewhat pink in the middle and not fully cooked. Earl wonders ifeating the hamburgers or the potato salad could be responsible formaking some attendees ill. Earl has begun to apply the scientificmethod to this common problem. Complete each of the following tasksin 200 to 300 words.

  1. How would the scientific method help Earl create an experiment to determine which food sources made people sick?

Byusing the scientific method to determine which food sources made thepeople sick was the best way to approach the situation as in the longrun Earl would arrive at a very accurate answer even though it takesmuch time. The scientific method gives room for more study andsuggestions hence making it a process of learning in itself. This isdone by the research carried out from other sources also (Finn&amp Louviere, 1992, pp. 12-22).

  1. Describe the steps of the scientific method Earl utilized.

Earlbegan by noting the problem of food poisoning and what he wanted tofind out, or rather the problem at hand was the case of foodpoisoning. He had a model already and that was the people who were inattendance for the picnic. He had different types of snacks andaccording to him, not every person did sample every snack he brought.Bringing us to the question, what was among the foods he brought thatcaused poisoning among the 30 people? He had a formed hypothesiswhich are the known facts about the poisoning and the problems thatcould be predicted. During the picnic, the known problem is the weirdcoloring in his hamburger and the temperature of his soup. He puts itto experiment on the people and records that of the 50 people, 30became ill (Finn&amp Louviere, 1992, p.15).

Theexperimental part involved setting up procedures.

Itis necessary to note what kind of materials have been used, thespecific dates the experimental study was carried out, variables,both independent variables which are constant and experimental anddependent variables. It is also necessary to find out what was donein order for the experiment to be set up. Fair procedures for testingare to be applied in this scenario. Earl made observations and tookdata. From there it was upon him to go and conclude his experimentand get an answer to his question (Finn&amp Louviere, 1992, p. 17)

  1. Describe the remaining steps Earl will use if he decides to use the scientific method to determine what made the people sick.

Interpretingof data is the next step Earl should apply. This step requires Earlto brainstorm and find out anything he can from the foods he carriedto the picnic. He can go ahead and do tests on the foods to determineany irregularities and also see if there was any natural cause forthe poisoning. He should justify his findings using concrete reasonsand draw concluding statements about his study. He should not forgetto include the problems he encountered or concerns that were raised.He should also broaden his study scope a bit and use other sources tosupport the conclusion. He should be in a position to givealternative ideas for the hypothesis tested (Finn&amp Louviere, 1992, p. 22).
