Scientific Method Exercise - Assignment Example

Scientific Method Exercise Affiliation: Part 1. What are the four steps of the Scientific Method included in the article?a. Background and theoryb. Hypothesisc. Data collectiond. Discussion and conclusion2. How do these steps correspond to the steps outlined in our textbook (Chapter 1)? The same? Different? Explain.The steps in the article are similar to those in the textbook. The only difference is that the steps in the article are limited and only a few are shown while those in the textbook are many and much more detailed (Larsen, 2011). 3. If you had to expand or combine steps from our text to match the steps from the article which would they be?

What was the justification for your choice?I would expand on the theoretical bit to explain on which theories were used and why, the data collection discussion on which were the specific methods and how they were used and finally on the hypothesis and whether it was testable in the end or not. Part 24. Please discuss the first possible cause of the extinction of the dinosaurs.Sex. There was an increase in the temperatures of the world which in turn affected the testes of the dinosaurs which hand outside the body causing sterilization.

The damage caused them to produce sperms for reproduction and hence their population eventually ended (Gould, 1984). 5. Please discuss the second possible cause of the extinction of the dinosaurs.Drugs. There was an evolution of flowering plants known as angiosperms which were toxic to the liver. The livers of the dinosaurs were unable to detoxify the substance and their tongues unable to taste the bitterness that would have prevented them from eating them. 6. Please discuss the third possible cause of the extinction of the dinosaurs.Disasters. Sunlight was blocked by dust raised by a large asteroid which landed on earth.

Temperatures were lowered and photosynthesis could not take place leading to massive loss of the animals (Gould, 1984). Part 37. Is the first possible cause a "hypothesis"? Why or why not?It is not a possible hypothesis. There is no way to test the dinosaur to verify about their body temperature being lower or higher than that of the earth and also no way of testing about whether or not they became sterile. 8. Is the second possible cause a "hypothesis"? Why or why not?This is possible as there is evidence of the dinosaurs being found in contorted positions from liver failure and also being the only mammals to die due to the flowers as the other mammals avoided eating them.9. Is the third possible cause a "hypothesis"?

Why or why not?It is possible based on research on asteroids falling on the earth during that period. It would also explain the reason the extinction of the dinosaurs happened during the same timeline and not over an extended period of time. ReferencesLarsen, C. (2011).
