Will adding different amounts of fertilizer to my crops affect the number of corn that grows?
1. ASK A TESTABLE QUESTION
Researching the problem before creating a hypothesis and experimenting gives a a more accurate hypothesis.
2. RESEARCH THE PROBLEM
I think that adding 100 liters of the fertilizer will help the most.
3. CREATE A HYPOTHESIS
In this experiment, the control is the field with no fertilizer. The field with no fertilizer helps to see the changes on the other fields with the fertilizer. The independent variable is the fertilizer, while the dependent variable is the number of ears of corn grown. The constant variables are the time that this experiment is being tested for, which is one month, and the fertilizer. Each field the fertilizer is being sprayed on, it is the same fertilizer solution, just different amounts.
4. PERFORM AN EXPERIMENT
5. ANALYZE DATA
In this step of the scientific method, making a graph is very helpful when comparing results.
