A good IA question is like a well-balanced pot: one clear independent variable you can actually control, a range with practical meaning, and at least five levels to see a pattern. So, "How does salinity from 0 to 40 ppt affect brine shrimp hatching?" works. But I see students get grand ideas with ten levels, then run out of time or money to measure properly. In my workshop, I know you test a glaze at three, maybe four temperatures—any more and you burn through gas and clay. The principle is the same.
