The next investigation should answer a specific remaining question
Choose a new test that addresses a specific uncertainty.
After testing wing width, a group may wonder about launch angle. Treat that as a new comparison with its own setup, rather than changing both features at once and losing the link between evidence and question.
After testing wing width, a group might test launch angle separately.
Follow one uncertainty into the next test
Make the follow-up narrower than the original broad topic. Explain how the new comparison addresses a particular uncertainty left by the first investigation.
Identify an unresolved result. Suggest one change. State what evidence to collect.
A new investigation needs its own controlled setup.
How will the new evidence help? Choose between two proposed tests.
