    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is not an example of a conclusion. It is actually a question about the effect of temperature on plant height. A conclusion is a statement that is reached after analyzing data or evidence. In this case, the statement is a question, not a conclusion.

    Rate this question:

  • 9. 

    How many variables should you TEST at a time in an experiment?

    • 283,283,845,238,954.23413383

    • 0

    • 1

    • 17

    Correct Answer
    A. 1
    Explanation
    In an experiment, it is recommended to test only one variable at a time. This is because testing multiple variables simultaneously can make it difficult to determine which variable is causing a specific outcome or effect. By testing one variable at a time, researchers can isolate and analyze the impact of that specific variable on the experiment's results.

    Which variable could be measured during an experiment?

    • Independent Variable

    • Dependent Variable

    Correct Answer
    A. Dependent Variable
    Explanation
    The dependent variable is the variable that is being measured or observed during an experiment. It is the outcome or result that is influenced by the independent variable, which is the variable that is manipulated or changed by the researcher. The dependent variable is dependent on the independent variable, as any changes in the independent variable can affect the dependent variable. Therefore, the dependent variable is the variable that could be measured during an experiment.

    A scientist plants two rows of corn for experimentation. She puts fertilizer on row 1 but does not put fertilizer on row 2. Both rows receive the same amount of water and light intensity. She checks the growth of the corn over the course of 5 months. What is one controlled variable in this experiment?

    • Amount of fertlizer given to experimental group

    • Growth of corn

    • Type of fertilizer

    Correct Answer
    A. Amount of fertlizer given to experimental group
    Explanation
    In this experiment, the scientist is comparing the growth of corn in two different conditions: row 1 with fertilizer and row 2 without fertilizer. The controlled variable is the amount of fertilizer given to the experimental group. By keeping the amount of fertilizer constant, the scientist can determine if the growth of corn is influenced by the presence or absence of fertilizer, while other factors like water and light intensity remain the same for both rows.

    Suzy wanted to know if thicker candles burn longer than thinner candles. Her hypothesis was that if she used a thick candle that it would burn for the longest amount of time. She got ten candles that were all the same brand, height, smell, and color. The only difference in the candles was they were all a different size, She lit them at the same time and recorded how long it took for each candle to burn out. What was her independent variable?

    • Thickness of the candle

    • Length of time the candle burned

    • Color of the candle

    Correct Answer
    A. Thickness of the candle
    Explanation
    The independent variable in this experiment is the thickness of the candle. Suzy is testing if thicker candles burn longer than thinner candles, so she is manipulating the thickness of the candles to see how it affects the burn time. The other variables, such as the length of time the candle burned and the color of the candle, are not being manipulated by Suzy and are therefore not independent variables in this experiment.

    Rate this question:

  • 21. 

    Which variable could be changed by the experimenter?

    • Independent Variable

    • Dependent Variable

    Correct Answer
    A. Independent Variable
    Explanation
    The experimenter has control over the independent variable in an experiment. This variable is intentionally manipulated or changed by the experimenter to observe its effect on the dependent variable. The dependent variable, on the other hand, is the variable that is being measured or observed and is expected to change in response to the independent variable. Therefore, the independent variable is the variable that could be changed by the experimenter.

    Rate this question:

  • 22. 

    Which could be a factor that remains at the same phases of an experiment?

    • Observation(s)

    • Science

    • Scientific Method(s)

    • Technology

    • Constant(s)

    Correct Answer
    A. Constant(s)
    Explanation
    In an experiment, a constant is a factor that remains unchanged throughout the entire process. It is not affected by any of the variables being tested. Constants are important because they provide a baseline for comparison and help ensure that any changes observed are due to the manipulated variables and not other factors. By keeping certain factors constant, scientists can isolate the effects of the variables they are interested in studying. Therefore, constant(s) is the factor that remains the same phases of an experiment.

    In an experiment, you water three sunflower plants with salt water. Each plant receives a different concentration of salt water solution. A fourth plant receives pure water. After a two week period, the height of each plant is measured. In this experiment, the plant height is which of the following?

    • The control

    • The DEPENDENT variable

    • The INDEPENDENT variable

    • Qualitative data

    Correct Answer
    A. The DEPENDENT variable
    Explanation
    In this experiment, the height of each plant is being measured after being watered with different concentrations of salt water. The height of the plants is the dependent variable because it is the outcome or result that is being measured and observed. The independent variable in this experiment is the different concentrations of salt water being used to water the plants. Qualitative data refers to non-numerical observations, so it is not the correct answer in this case.

    Janet wanted to see if the height of a person affected the length of their handspan. She measured three people's heights, and measured their handspans. She found that the taller a person is, the longer their handspan is. What is wrong with her experiment?

    • She tested too many variables at once.

    • She did not test a large enough sample of people.

    • She did not control all of the variables.

    Correct Answer
    A. She did not test a large enough sample of people.
    Explanation
    The correct answer is that she did not test a large enough sample of people. In order to draw accurate conclusions, it is important to have a sufficient sample size that is representative of the population being studied. By only measuring three people, Janet's sample size is too small to make generalizations about the relationship between height and handspan. A larger sample size would provide more reliable data and allow for better analysis of any potential patterns or trends.
