This is the hypothesis stage of the scientific method. Let's look at the different stages to find this answer.
Problem- Something you do not know and would like to find out Research- Information you gather to help you come to a prediction HYPOTHESIS- A prediction about what the experiment will show Experiment- Testing the variables to see the outcome Organization- Putting your data from the experiment into a table or graph so that it is easy to understand Summary- Generally a few sentences, an overall summary of what happened in the experiment including the "befores," "durings," and "afters." Distribution- Making your information public so that other scientists can use it for research.
After reviewing all of the steps, we can see that the correct answer is certainly hypothesis.
