  1. Two scientists conduct the same experiment and get different results. What is the best next step?

    Answer: Replicate the experiment multiple times to check for consistency.

    Replication is essential to scientific validity; repeated experiments help determine which result is reliable.

  2. A bar chart shows average rainfall for four cities. City B's bar is twice the height of City A's. What does this indicate?

    Answer: City B receives twice as much rainfall as City A.

    Bar height directly represents the measured quantity; double the height means double the rainfall.

  3. Which unit would most likely be used to measure the mass of a small laboratory sample?

    Answer: Grams

    Grams are the standard SI unit for measuring small masses in laboratory settings.

  4. A scientist records data over several weeks and notices a consistent upward trend. This trend is best described as:

    Answer: A positive correlation over time

    A consistent increase over time represents a positive correlation between time and the measured variable.

  5. What is the purpose of a control group in a scientific experiment?

    Answer: To provide a baseline for comparison with the experimental group

    A control group establishes the standard outcome under normal conditions so the effect of the independent variable can be isolated.

  6. A scatter plot shows data points clustered closely around an upward-sloping line. This indicates:

    Answer: A strong positive correlation between the two variables

    Points tightly clustered around an upward-sloping line indicate a strong positive correlation.
