Plant A is receiving sunlight , soil, and regular water, plant B is also receiving sunlight, soil, and regular water. Yet Plant B is ALSO getting fertilizer. Write a hypothesis of what will happen to the plants as they grow over the next few weeks. Hypothesis



Answer :

A hypothesis expresses clearly the relationship between two variables and what is expected to occur. If plants receive fertilizer, then they will grow taller than plants that do not receive fertilizer.

What is a hypothesis?

When following the scientific methodology, researchers must formulate a hypothesis.

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, not a fact. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes to predict what is going on or what is expected to occur.

A hypothesis must,

  • be clear and comprehensive.
  • express the direct relationship between the involved variables.
  • be objective.
  • be testeable and falsifiable

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.  

In the exposed example we have

  • plants A and B exposed to the same environmental conditions ⇒  sunlight , soil, and water.
  • plant B receiving fertilizer

The variables are,

  • Controlled variables: sunlight , soil, and regular water
  • Independent variable: fertilizer presence/absence
  • Dependent variable: plant growth

The hypothesis must explain the relationship of the dependent and independent variables as a cause and effect event. So,

If plants receive fertilizer, then they will grow taller than plants that do not receive fertilizer.

There are several ways in which you can propose a hypothesis like this one. You just need to make sure both variables are mentioned and what the effect of the independent on the dependent variable is.
