"How do children naturally interact with each other on a playground?"
Explanation: that's a descriptive question about naturally occurring behavior and can be answered by observing without manipulating anything. The others ask about effects of interventions (app, light levels, diet), which are best studied with experiments (random assignment) to establish causal effects — observational studies could collect associations but provide weaker causal evidence.
