A question such as “does light affect plant growth?” needs a measurable definition of growth, comparable plants and controlled conditions. Height alone may not tell the whole story. Record the light treatment, time, water and repeated measurements before drawing a conclusion. This pack supports school science topics; it is not a complete GCSE, US high-school or European course. Your own syllabus determines the required depth.
