Assess the ability to design and interpret a controlled experiment testing how light, temperature, and moisture affect seed germination: formulate a clear hypothesis, identify independent, dependent and controlled variables, choose appropriate controls and replication, outline a stepwise procedure and measurement plan (timing, germination criteria, sample size), describe data recording and basic analysis (means, variability, simple graphs), and interpret hypothetical results including sources of error and ecological or practical implications. Scope includes experimental design, data presentation, and reasoned conclusion-drawing at a medium difficulty (apply-level).
