True

False

Test one sheet of each brand, using different amounts of water and different soaking times.

Test several sheets of each brand with the same amount of water and the same timing.

Test several sheets of each brand, but change the water amount for each brand.

Test one sheet of each brand and choose the result that best fits the expected pattern.

True

False

Conclude that extra light caused the growth because the seedlings grew taller.

Give the seedlings different amounts of water in a follow-up test.

Keep water, soil, seed type, and other relevant conditions the same while changing the amount of light.

Compare seedlings grown in different soils and with different amounts of water.

State the question investigated and the claim supported by the results.

Describe what was changed, measured, and kept the same, and how measurements were collected.

Present the results, including data that do not fit the expected pattern.

Explain how the results support, challenge, or qualify the claim.

Identify limitations and uncertainty that could affect the conclusion.

Claim that the conclusion is true in every setting, even if only a limited range was tested.

Suggest further tests that could help answer an unresolved question.

Remove results that differ from the average so the pattern is clearer.

Change several parts of the method at once so the next results are different.

Standardize the procedure, consider a more suitable measuring tool, and collect more trials.

Keep the method unchanged and report only the result that occurred most often.

Use equal-sized pieces of each paper towel brand.

Use the same water volume and soaking time for every test.

Use a different water volume for each brand to make differences easier to see.

Repeat the test several times for each brand.

Discard trials that do not match the expected result.

Repeat only the measurements from the part of the range where a pattern already appeared.

Collect data at additional values to check whether the pattern continues across a wider range.

Conclude that the pattern applies at all possible values.

Ignore the part of the range where no pattern appeared.

Test one sheet from each brand, using different amounts of water so each sheet is tested thoroughly.

Test several sheets from each brand using the same amount of water and the same timing.

Test several sheets from one brand and assume the other brands will behave similarly.

Choose the sheet from each brand that looks most absorbent before adding water.

True

False

Brand A is the most absorbent brand in every setting.

Every sheet from Brand A absorbs more water than every sheet from other brands.

Brand A absorbed more water on average than Brand B under the conditions tested.

Brand A will absorb more water than any brand that was not included in the test.

Report the observed data and explain separately how they support or qualify the claim.

Include only the data that match the expected pattern, then state the claim confidently.

State the claim without describing how the measurements were collected.

Present the interpretation as if it were a direct measurement.

Remove results that do not fit the predicted pattern before deciding what happened.

Investigate the unexpected results and consider whether they reflect variation or a problem with the method.

Repeat the investigation only until the expected pattern appears, then report those results.

Ignore inconsistent results if most measurements support the original claim.
