im in 9th grade and i need a topic to do my experiment on, the experiment has to last 3 months. My teacher wants to challenge us so i need a REALLY hard one. Remember it has to last 3 months.
i need a hypothesis and make an experiment out of it trying to prove that it's true.
EX: How can the Ph level effect the growth of plants?
