A student will measure and record the growth of two flowering plants every day for 28 days. Plant A will be watered and fertilized, Plant B will only be watered. The student predicts fertilizer added to the soil leads to taller flowering plants. Scientific conclusions are based on scientific evidence, what evidence would support the student’s prediction?
Research articles that have been published about the subject, apply polls to people that work with plants to know about their experience, ask classmates that already made this experiment.
