    Summary Introduction

    To write:

    The given hypothesis is based on the observation and tries to solve the problem that comes in daily life.

    Introduction:

    The scientific test allows us to determine the occurrence of any phenomenon occurring in nature as well as our day to day life. The scientific experimentation needs a hypothesis to test, which can be correct or incorrect. The test of the results determines whether the proposed hypothesis can be accepted or not.

    Explanation of Solution

    Observation: The observation is the visible or observable record, which is the outcome of the tests performed. Hence, the observation would be that my toaster does not toast my bread and my coffee maker does not work. Hence, the sentences (c) and (e) are the observations.

    Question: The question is something, which is asked, in order to find a solution. In this case, the question would be why doesn’t my toaster work? Hence, the sentence (f) is the question.

    Hypothesis (answer): Hypothesis is the predicted result, which is testable. The hypothesis, in this case, is there is something wrong with the electrical outlet. Hence, the sentence (a) is the hypothesis.

    Prediction: The prediction is an assumption made in order to perform the experiment related to the hypothesis. In this case, the prediction can be If the outlet is not working properly, my coffee maker won’t work when plugged in. Hence, the sentence (b) is the prediction.

    Experiment: The experiment is the test performed by the person to test the hypothesis. In this case, the experiment is plugging in the coffee maker to test if the outlet is working or not. Hence, the sentence (d) is the experiment.

    Result: The result is the outcome of the experiment. In this case, the coffee maker works are the result. Hence, the sentence (e) is the experiment.

    As the hypothesis about the electrical output is not working is incorrect and it is proved by testing the coffee machine, hence, this hypothesis cannot be accepted. The possible hypothesis can be that there is something wrong with the toaster.

    Conclusion

    The hypothesis given by the person about the electrical output is incorrect. Hence, it cannot be accepted. The person thinks that the toaster is not working due to the problem with electrical output, it is proven to be incorrect by testing the coffee machine. Hence, another hypothesis, which suggests some problem with the toaster can be correct.

    Consider 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.
    (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 data
