Answer:
They know that they will need to use the hypothesis and perform an experiment. They are using the scientific method.
Explanation:
To study whether sugar really affects teeth, students should use a hypothesis that allows them to start an experiment.
The hypothesis is the premise about a certain element that needs to be studied. In this case, students can use the hypothesis that sugar causes tooth decay, or the hypothesis that sugar strengthens teeth, or any other assumption that they believe that sugar causes teeth.
This hypothesis will allow them to stipulate a scientific experiment, which will allow them to assess the influence of sugar on their teeth and determine whether their hypothesis is correct or incorrect.
This is called the Scientific Method, which is a set of steps that allows the analysis and study of situations that occur in our universe, through scientific experiments.
