A student proposes, “More daily light increases bean seedling growth because light provides energy for photosynthesis.” Which option correctly pairs this hypothesis with a prediction?

A
The hypothesis is that more daily light increases seedling growth; the prediction is that seedlings receiving more light will be taller after 14 days.
B
The hypothesis is that seedlings will be taller after 14 days; the prediction is that light provides energy for photosynthesis.
C
Both statements are hypotheses because both mention light and growth.
D
Both statements are predictions because they describe seedlings.

1 point

An investigation produces evidence that does not agree with its prediction. Select all responses that are appropriate scientific next steps.

A
Review whether the method, measurements, or assumptions need attention.
B
Discard the hypothesis immediately without checking how the evidence was collected.
C
Revise the proposed explanation in light of the evidence.
D
Improve the method or ask a new question.

1 point

Select all statements that accurately describe how scientists choose methods for investigations.

A
The method should be suitable for the question being investigated.
B
Some questions can be answered through observations or analysis of existing data rather than an experiment.
C
Every scientific investigation must follow the same steps in the same order.
D
Different scientific questions may call for different ways of gathering evidence.

A student predicts that a certain treatment will increase plant growth. The measurements are reliable, but treated plants do not grow more than untreated plants. Which conclusion best fits the evidence?

A
The hypothesis is certainly false in every situation.
B
The investigation proves the opposite hypothesis is true.
C
The evidence does not support the hypothesis under the conditions investigated.
D
The prediction must be correct even though the measurements disagree.

A student notices that two brands of paper towel seem to absorb different amounts of water. Which statement is the clearest hypothesis to investigate?

A
Paper towels are fascinating and should be studied.
B
Differences in the towels’ absorbency may be related to their material, which can be tested by comparing how much water each absorbs.
C
Paper towels are the best kind of towel.
D
Paper towels will absorb different amounts of water.

B
Every investigation must follow the same steps in exactly the same order.
C
