Choose an answerable scientific question

Supplied materials

• All measurements and observations below are supplied classroom examples. They are not data from actual learners or a claim about a particular real site.
• Paper or a browser document for a labeled drawing, table or explanation.
• Worked problem inputs: A question asks whether a model cover reduces water loss under matched inputs. Define the measurable comparison.
• Assessment case 1: A cover trial holds input volume/time fixed and compares measured loss for A and B. Which question matches? Which inference or prediction is best supported?
• Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Which cover color do you like.
• Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Which thing is best for everything.
• Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: How can a paper cover meet load and budget limits.
• Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Does output differ under matched supplied inputs.
• Assessment case 6: A paper model must retain 20 L using at most four supplied panels. What makes a testable design question? Which inference or prediction is best supported?

Learn the idea

A scientific question specifies measurable variables and scope. A preference question may be useful but differs from a physical measurement. The supplied capstone cases require no laboratory or external participant.

Measurable question means names quantities and comparison. Preference question means asks what a person likes. Overbroad question means lacks defined variables or scope. Design question means asks how to meet specified criteria.

For the supplied mechanism problem, A question asks whether a model cover reduces water loss under matched inputs. Define the measurable comparison. Specify cover arrangement as the changed feature and recorded water loss as outcome, with the same input, duration and boundary. This supports an answerable comparison rather than an undefined best-cover claim.

1. Read the supplied problem and mark the structures, processes or quantities named: A question asks whether a model cover reduces water loss under matched inputs. Define the measurable comparison.
2. Draw the relevant boundary, pathway or comparison and label it using the scientific ideas above.
3. Write a causal explanation or calculation, showing how each observation supports the result.
4. Compare your reasoning with the worked solution; name a condition that would change or limit the inference.

Take it further

New question compares filter A and B under equal input counts and duration. Expected: name filter design as changed feature and retained target-particle fraction as measured outcome; define the particle category and boundary.
