- Explain what Avery’s experiment showed in 1944. Briefly describe the idea behind the experimental set up. Mention the step by step findings and the conclusions.(1 question with multiple steps please answer) Identify the component characteristics of a scientific investigation Suggest alternative hypotheses that could be tested by the design Evaluate the validity of conclusions based on the given results Suggest ways to improve the experimental design Define and recognize examples of the experimental group, experimental variable, control group, control variable, independent variable, and dependent variable, and dataI answered with a and c but keep getting told its the wrong answer. Which of the following is not a component of effective experimental designs in the early stages of a scientific study? Select one or more: a. small sample sizes b. experimental groups taking a placebo c. double blind experiments d. short duration e. animal models f. repetitive testing
- Theories change as new information becomes available. Which actions are most likely to lead to the discovery of new information? Check all that apply. 1.repeating experiments using the same experimental method each time 2.repeating experiments using the technology available at the time of the original experiment 3.repeating an experiment using the latest technology 4.developing a new experimental method to test an existing hypothesisWhich of the following types of experiments is the same as a conventional lab experiment but does NOT use student samples? O Natural field experiment Framed field experiment O Artefactual field experimentDesign a (hypothetical) experiment that adheres to the Scientific Method. Be sure to include all the necessary requirements at each step and give examples at all of the steps. Start with an observation, whether it's real or made up, state the null hypothesis, and design an experiment (including an experimental and control group, random sampling, sample size, and reproducibility) that will allow the student to reject or fail to reject the hypothesis, and state (hypothetical) 'actual' results and the appropriate conclusion to draw from those results.
- Compare and contrast Spallanzani’s, Pasteur’s, and Tyndall’s experiments that tested spontaneous generation.a) Does the data support your hypothesis? b) How could you improve this experiment? Consider the other factors you could have / should have controlled in this experiment.Stage of Scientific Method: 1. Defining the Problem 2. Formulating the Hypothesis 3, Testing the Hypothesis 4. Making and recording observations 5. Drawing Conclusionsguide question: How did Pasteur Follow the method?

SHOW MORE Observation/Problem Hypothesis Experimental Idea Experimental Test Result III III I plug my coffee maker into the outlet. My coffeemaker works. If something is wrong with the outlet my coffeemaker also won't work when plugged into it. There is something wrong with the electrical outlet. My toaster doesn't toast my bread.Why do scientists design experiments to disprove the hypothesis they are testing instead of trying to prove that the hypothesis is correct?According to this experiment, summarize it and be sure to address the following questions: What hypothesis was being tested? How did you test your hypothesis? What independent and dependent variables were being investigated? What controls did you use? What were possible sources of error in your experiment? Please explain how the experiment you conducted supported or failed to support the original hypothesis.
