    All hypothesis should be written as an _______________________  statement.

    • I think

    • Sometimes crazy things happen in science

    • If/Then

    • Because

    Correct Answer
    A. If/Then
    Explanation
    All hypothesis should be written as an "If/Then" statement because this format allows for a clear and logical expression of the cause-and-effect relationship being investigated. The "If" part of the statement represents the independent variable or the factor being manipulated, while the "Then" part represents the dependent variable or the outcome being measured. This format helps to establish a clear connection between the variables and allows for the formulation of testable predictions.

    • Pimple reduction

    • Temperature

    • Skin type

    Correct Answer
    A. Acne medicine
    Explanation
    The independent variable in this question is "acne medicine".

    Nick wanted to see how high an ice cube would float in different temperatures of water. Identify the independent variable

    • How high an ice cube floats

    • What type of liquid Nick is using

    • Temperature of water

    Correct Answer
    A. Temperature of water
    Explanation
    The independent variable in this experiment is the temperature of water. This is because it is the factor that is being manipulated or changed by Nick in order to observe its effect on how high the ice cube floats. The height at which the ice cube floats is the dependent variable, as it depends on the independent variable (temperature of water) and is being measured or observed in response to the changes in temperature. The type of liquid Nick is using is not relevant to the independent variable in this experiment.

    • Fertilizer

    • Size of plant

    • Water, sunlight, amount of dirt

    Correct Answer
    A. Fertilizer
    Explanation
    The independent variable in this scenario is the fertilizer. It is the factor that is being manipulated or controlled by the person conducting the experiment. By using fertilizer on the tomato plant, the person is testing the effect it has on the size of the plant.

    Does an expensive brand of shampoo make my hair shinier?  Identify a constant in the experiment

    • Length of wash time

    • Water temperature while washing

    • Amount of shampoo

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    In order to determine if an expensive brand of shampoo makes hair shinier, all of the mentioned factors need to be considered as constants in the experiment. The length of wash time, water temperature while washing, and the amount of shampoo used should remain the same throughout the experiment. By keeping these variables constant, any differences in hair shininess can be attributed to the shampoo itself, allowing for a fair and accurate evaluation of its effectiveness.

    If I use fertilizer on my tomato plant, then my tomato plants will grow bigger. What would be a constant for this experiment?

    • Fertilizer

    • Size of tomato plant at end of experiment

    • Amount of sunlight

    Correct Answer
    A. Amount of sunlight
    Explanation
    In this experiment, the constant refers to the factor that remains consistent throughout the experiment and does not change. In this case, the amount of sunlight would be the constant because it is not being manipulated or changed. The experiment is focused on the effect of fertilizer on the size of tomato plants, so the amount of sunlight remains constant to isolate the impact of the fertilizer on plant growth.

    IF I take a yoga class, THEN my flexiblity will increase.  Find the Independent Variable

    • My yoga instructor

    • Flexibility

    • Taking a yoga class

    Correct Answer
    A. Taking a yoga class
    Explanation
    The independent variable in this scenario is "taking a yoga class". This is because it is the variable that is being manipulated or controlled by the individual. By choosing to take a yoga class, the person is actively making a decision to engage in this activity, which may have an effect on their flexibility. The other options, "my yoga instructor" and "flexibility", are not being directly manipulated or controlled by the individual and therefore do not qualify as independent variables.

    The final step of the scientific method is to

    • Stop researching

    • Form a conclusion and then think of a new question and start the process over

    • Form a conclusion and never think of the experiment again

    • None of the above

    Correct Answer
    A. Form a conclusion and then think of a new question and start the process over
    Explanation
    The final step of the scientific method is to form a conclusion and then think of a new question and start the process over. This is because the scientific method is an iterative process, where each experiment and its conclusions lead to new questions and further research. It is important to continue questioning and testing hypotheses to further advance scientific knowledge.
