  1. Which of these is the correct SI unit for measuring mass?

    • Pounds
    • Grams
    • Inches

  2. Which part of a science report states what you think will happen, before you start the experiment?

    • Hypothesis
    • Conclusion
    • Evaluation

  3. Peer review means other scientists check a report before its findings are trusted.

    Circle one:   True   False

  4. A report's results section says: 'The plant grew a lot.' What is this missing?

    • Exact measurements with units
    • A hypothesis
    • A peer review

  5. A report needs to record 45000000 m. Written correctly in standard form, this is:

    • 4.5 × 10^6 m
    • 45 × 10^6 m
    • 4.5 × 10^7 m

  6. A sample has a mass of 2.5 kg. Written in grams for the results table, what number should you write?

    Answer: ______________

  7. Two labs get different results from the same experiment. Why might scientists hold off on accepting the first lab's finding as fact?

    • Standard form wasn't used correctly
    • The evaluation section was too short
    • It hasn't been peer reviewed and replicated by others

  8. A classmate's report has only five sections: aim, method, results, conclusion, evaluation. What is missing?

  1. Grams · Grams (g) and kilograms (kg) are SI units for mass. Pounds and inches are not SI units.
  2. Hypothesis · The hypothesis is your prediction, written before you run the experiment.
  3. True · Peer review is when other experts examine a study to check it's sound before anyone relies on it.
  4. Exact measurements with units · Results need exact numbers with units, like '4.2 cm', not vague words like 'a lot'.
  5. 4.5 × 10^7 m · Move the decimal point until one digit sits in front of it: 4.5 × 10^7 m has the same value as 45,000,000 m.
  6. 2500 · 1 kg equals 1000 g, so 2.5 kg converts to 2500 g.
  7. It hasn't been peer reviewed and replicated by others · A single result needs peer review and independent replication before it becomes accepted scientific knowledge, especially when results disagree.
  8. Hypothesis · A hypothesis is the prediction that comes before the method. Without it, a reader doesn't know what result was expected.
