Solved in 2 steps
- Design 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.Explain the differences between independent, dependent and controlled variables in an experimentWhat variable is the one that you can manipulate or change? It is sometimes called experimental variable
- You are asked to draw and explain the goal of the Meselson-Stahl (1958) Experiment as outlined in the classroom. You need to draw your own diagram and use short sentences to explain the steps and/or important points, deductions. Clearly state what happens at each step.Instruction: Go outside and observe your surroundings. From your observation, formulate a hypothesis and design an experiment that will test your hypothesis. Provide a predicted result of your experiment.What is control group? Explain the purpose of a control in an experiment.
- What are three important thing you will consider when settting up an experiment to investigate a phenomenon? Explain why?Question 1 Match the steps of the scientific process given on the right to answer each question below. Each step may be used once, more than once, or not at all. What is the first step in the scientific process? stating the question After stating the problem, what is the next step? forming a hypothesis Deciding what kind of data to gather takes place during which step? forming a hypothesis Which step comes after conducting the experiment? [ Choose When are variables and controls determined? |Choose J Which step gives a possible explanation to a problem that can then be tested? [ Choose J If an idea can be supported over and over again, it may proceed to which step? | Choose ) Data is gathered during which step? [ Choose J During which step is the hypothesis supported or rejected? | Choose J > > > > > > > >What is the difference between an independent and dependent variable. Provide an example of each from a hypothetical experiment.
- Why is it important to have a control for an experiment?Which of these statements are true about predictions and hypotheses? (4 are true) □ If the results of the experiment are NOT consistent with a given prediction then that hypothesis is false. O Hypotheses and predotions are the same as theories. A predictions is a possible explanations to explain the initial observation. Predictions and hypotheses are the same thing. Predictions are usually written as if/then statements. "If I do this, then that will happen." O The prediction step comes before the hypothesis. Hypotheses are usually written as if/then statements. "If I do this, then that will happen." A hypothesis is a possible explanations to explain the initial observation. O The prediction step comes after the hypothesis.The null hypothesis is: That the measured value is zero That the proposed model is not correct and the measured factors have no effect on the pattern That the proposed model is correct and perfectly explains the pattern That the experiment is null and void
