- The type of logical thinking that uses related observations to arrive at a general conclusion is called_______. a. deductive reasoning b. the scientific method c. hypothesis-based science d. inductive reasoningarrow_forwardWhy do scientists design experiments to disprove the hypothesis they are testing instead of trying to prove that the hypothesis is correct?arrow_forwardScenario 1: You are running a marathon and observe that running increases your pulse rate. Using what you know about the scientific method complete the following: 1. Write a hypothesis:2. Independent variable:3. Dependent variable:4. Controlled variables (at least 3):a.b.c5. Control Treatment:6. Experimental Treatment: Scenario 2: Sarah kicked a fully inflated soccer ball 100 times and measured how far it traveled. Next, she kicked a partially inflated soccer ball 100 times and measured how far it traveled. 1. Write a hypothesis:2. Independent variable:3. Dependent variable:4. Controlled variables (at least 3):a.b.c5. Control Treatment:6. Experimental Treatment:arrow_forward
- Why is forming a hypothesis an important step in the scientific method? Choose the best answer. Stating a hypothesis before conducting experiments ensures that the method will follow an inductive process of reasoning. By stating a formal hypothesis, a scientist can adequately design the best control conditions for designing experiments intended to falsify the hypothesis. When a formal hypothesis is tested once, it will be accepted as theory no matter what the results of subsequent experiments suggest.arrow_forwardWhich of the following is not true of science?a. Science is based on the premise that all events can be traced to natural causes.b. Important science can be based on chance observations.c. A hypothesis is basically a wild guess.d. Scientific theories can potentially be disproved.arrow_forwardWhat are three important thing you will consider when settting up an experiment to investigate a phenomenon? Explain why?arrow_forward
- How do scientists derive testable hypotheses? Explain with an example?arrow_forwardSandra claims that invisible fairies live above the clouds where no one can see, hear or feel them. Which of the following is true? Sandra's claim is a hypothesis that she could test with the scientific method. Sandra's claim is not scientific because it is not testable. Sandra's claim is a law based on empirical evidence. Sandra's claim is not scientific because no one famous would agree with her.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_forward
- Identify each statement below as S if it can be tested scientifically or N if it is non-empirical knowledge. Explain your answer. a. Leonardo da Vinci is a better painter than Picasso is. b. Alcohol consumption by pregnant women may cause birth defects in their babies. c. There is a God. d. The sun rises in the east every morning.arrow_forwardThe 'control group' is an essential component of an experiment. This is because 1. A control group allows one to determine if a particular result is due to the experimental variable. 2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment. 3. A control group allows for multiple variables to be tested at the same time. 4. A control group is required for the development of a prediction.arrow_forwardConsider the steps involved in an experiment that uses the scientific method. Arrange the six given steps in the order in which they occur. One of the steps will not be used. First step of investigation Final step of investigation Answer Bank Share the results and conclusions of the experiment. Choose the data that are most likely to support the hypothesis and ignore the rest of the data. Conduct the experiment and collect the resulting data. Make observations that raise a question about some aspect of a natural phenomenon. Analyze the data collected in the experiment. Form a hypothesis that can answer the question about the natural phenomenon. Design an experiment that tests the hypothesis.arrow_forward
