Chapter 1, Problem 2ACQ
Figure 1.18 In the example below, the scientific method is used to solve an everyday problem. Which part in the example below is the hypothesis? Which is the prediction?
Based on the results of the experiment, is the hypothesis supported? If it is not supported, propose some alternative hypotheses.
1. My toaster doesn’t toast my bread.
2. Why doesn’t my toaster work?
3. There is something wrong with the electrical outlet.
4. If something is wrong with the outlet, my coffeemaker also won’t work when plugged into it. 5. I plug my coffeemaker into the outlet.
6. My coffeemaker works.

Observation:
Students on a university campus notice that the freshly squeezed mango juice ferments faster than the freshly made lime juice even though they are made by the same vendor, using the same method of juice extraction, and kept at the same temperature.
Write a simple hypothesis, null hypothesis and alternative hypothesis
The scientific method is the process that scientists use to find out new information. It involves a question, a hypothesis, a prediction, collecting data, and analyzing that data to make a conclusion. How would you use the scientific method to answer this question: Do mice live longer when they are fed high-sugar diets?

- Why do scientists design experiments to disprove the hypothesis they are testing instead of trying to prove that the hypothesis is correct?arrow_forwardA person notices that her houseplants that are regularly exposed to music seem to grow more quickly than those in rooms with no music. As a result, she determines that plants grow better when exposed to music. This example most closely resembles which type of reasoning? inductive reasoning deductive reasoning neither, because no hypothesis was made both inductive and deductive reasoningarrow_forwardWhich of the following is not a feature of a scientific theory? a. It begins as a hypothesis. b. It eventually is accepted as absolute truth. c. It requires critical thinking. d. It is not accepted as a theory until it has been tested repeatedly.arrow_forward
- Can a theory be proven wrong?a. No, theories are exactly the same as facts.b. No, because there is no good way to test a theory.c. Yes, a new observation or interpretation of data could disprovea theory.d. Yes, theories are exactly the same as hypotheses.arrow_forwardWhich statement below correctly identifies the difference between laws and theories? Laws describe phenomena, while theories explain why phenomena exist. Laws are a statement of fact, while theories are a statement of opinion. Laws explain why phenomena exist, while theories explain how.

- WHAT ELSE CAN I ADD TO THIS: A hypothesis is "a proposed explanation for a set of observations. A prediction would occur after you form a hypothesis. You would make a prediction regarding your hypothesis and then work to gather more information, test the hypothesis through experiments and this will help you determine if your hypothesis is correct and make a conclusion. An example of this might be my phone continues to die quickly despite being fully charged. My hypothesis is that my phone is dying quickly because I have a defective battery. My prediction is that replacing the battery will solve the problem. I can then test that hypothesis by replacing the battery and determine if that solves the problem.arrow_forwardWhat is the difference between a scientific theory and a hypothesis? Why do scientists refer to basic scientific principles as “theories” rather than “facts”?arrow_forwardWhat did Thomas Kuhn propose? What observations were responsible for his proposal for how scienceworks? Where did he get his ideas? -philosophy of sciencearrow_forward
- When you make important decisions about life, do you use any of the steps in scientific method? Compare a person's typical decision‐making process to the scientific method. Which of the steps in the scientific method do we typically use and which do we omit?arrow_forwardBased on the results depicted above, what do you conclude about your hypothesis? Give specific explanations for this conclusion. This should read like part of a discussion in a lab report, with analysis of the results and comparison back to the hypothesis.arrow_forwardNew things to investigate are continually being discovered. For example, modern medical imaging technology allowed biologists to discover structures called the "interstitium" that are now being evaluated as a new organ because of their importance in the physiology of the human body. Although they have different approaches for investigating scientific phenomena, the three types of scientific inquiry work together to help scientists understand phenomena. When something new is discovered, the first types of scientific inquiry will be [ Select ] ["hypothesis-driven experiments", "develop models/theory", "observational descriptive studies"] . Once these initial studies lay a foundation of knowledge about the new discovery, [ Select ] ["hypothesis-driven experiments", "observational descriptive studies", "develop models/theory"] can begin to test various aspects related to it.
