  1. A teacher asks students to predict what will happen to a plant kept in the dark for two weeks. This activity primarily develops which scientific skill?

    Answer: Hypothesis formation

    Asking students to predict outcomes before an experiment develops hypothesis formation skills, a core scientific inquiry process.

  2. Which of the following best describes a controlled variable in a science experiment?

    Answer: A variable that is kept constant throughout the experiment

    A controlled variable is one that is held constant so it does not influence the outcome, allowing a fair test of the independent variable.

  3. Students sort rocks into groups based on texture and color. Which process skill are they practicing?

    Answer: Classifying

    Sorting objects into groups based on observable characteristics is the process skill of classifying.

  4. A scientist observes that oil spills near a coastline coincide with declining bird populations. This is best described as:

    Answer: A correlational observation

    Noticing that two variables change together without manipulating either one is a correlational observation, not proof of causation.

  5. Which measurement tool would be most appropriate for a student to use when determining the volume of an irregular-shaped rock?

    Answer: Graduated cylinder with water displacement

    Water displacement in a graduated cylinder is used to find the volume of an irregular solid that cannot be measured directly with a ruler.

  6. Which of the following is the most accurate statement about scientific theories?

    Answer: A theory is a well-substantiated explanation supported by repeated testing

    A scientific theory is a well-supported explanation of natural phenomena based on extensive evidence and repeated testing.

  7. A student records data from an experiment but notices one result is very different from all the others. What should the student do first?

    Answer: Repeat that part of the experiment to check the result

    An anomalous result should prompt the student to repeat the trial to determine if it was an error or a genuine finding.
