  1. What does reporting the results of a science test mean?

    • Writing or telling others what happened in the test
    • Keeping the results hidden and describing only the tools used
    • Choosing the result you hoped for and leaving out what happened

  2. What should the conclusion of an investigation do?

    • List the tools used without explaining what the results show
    • Answer the starting question using the results
    • Describe a future test without answering the starting question

  3. Your report should include the results you observed, even when they differ from your prediction.

    Circle one:   True   False

  4. In two fair tests, Towel B took up more water than Towel A. New pieces will be tested under the same conditions. Which prediction uses these results?

    • Towel A must take up more next time because it took up less in both earlier tests
    • Both towels must take up no water next time because they have already been tested
    • Towel B may take up more again, but the new test needs to check

  5. Equal-sized sponges received the same test. A took up 4 mL of water, B took up 7 mL and C took up 9 mL. Which conclusion matches these results?

    Sponge A4Sponge B7Sponge C9
    • Sponge A took up the most water in this test
    • Sponge C took up the most water in this test
    • All three sponges took up the same amount of water in this test

  6. A class tested one piece of each towel. Which improvement would help them check whether their result happens again?

    • Test several pieces but give each towel a different amount of available water
    • Test just one piece again but give each towel a different amount of soaking time
    • Repeat with fresh equal-sized pieces and the same conditions

  7. In the same test, Towel E took up 12 mL of water and Towel F took up 7 mL. How many fewer mL did F take up than E?

    Answer: ______________

  8. Maria investigated which towel took up the most water. Her conclusion says only, 'I liked Towel B best.' What is missing?

    • An answer supported by the measured results
    • A longer description of how much she liked the towel's colour
    • A list of the towels' names without any of the measured results

Making sense of what you found W1-mt_7VrR1GzhrN-s1

  1. Writing or telling others what happened in the test · Reporting shares what happened so other people can understand your investigation.
  2. Answer the starting question using the results · A conclusion connects your results to the question you investigated.
  3. True · A report describes what happened. A prediction describes what you expected.
  4. Towel B may take up more again, but the new test needs to check · B took up more in both tests. That gives a reason to predict a similar result, though the next result is still uncertain.
  5. Sponge C took up the most water in this test · 9 mL is greater than 7 mL and 4 mL. Sponge C took up the most water in this test.
  6. Repeat with fresh equal-sized pieces and the same conditions · Repeated fair comparisons help check whether the result is consistent across fresh pieces.
  7. 5 · 12 minus 7 equals 5. F took up 5 mL fewer than E.
  8. An answer supported by the measured results · A preference does not answer which towel took up the most water. Maria needs to use her measurements.
