Steps in the order they should occur:

Observes that there are acidic foodsAsks a question about food’s acidityCreates a hypothesis about the acidityPrepares to conduct the experimentThe student records the acidity of the food.Presents the results to the class

Explanation:

This question is addressed to reflect on the scientific method, and so it deals with the logical steps that are followed regularly in such process.

It is the observation of a natural phenomenum what sparks the whole process. In this case, the student observes that there are acidic foods.

After such observation, some minds, the curious minds, start to ask questions: why?, how?, when?, what happens if? Numerous questions might arise, it is the curiosity attitude, that accompanies the scientific mind. So, the student asks a question about food’s acidity.

The trained scientist then elaborate a hypothesis : a logical tentative prediction which relates a thesis and a conclusion, in the form if then , addresed to answer the question. This hypotheisis must be testable, so it must contains objective variables, which can be verified through an experiment by measurements that can be replicated by any one. So, at this point fhe student creates a hypothesis about the acidity.

The next steps are:

Prepares to conduct the experiment: the student must select the independent, dependent and control variables, and plan the materials and equipment needed, the place, the time, the budget, and the special conditions to perform the experiment.The student records the acidity of the food: the experiment is run and the data is recorded, and analyzed, to drive a conclusion:Presents the results to the class: this is how science evolve. The presentation of the results is important because 1) permits the validation of the results by the community, and 2) permits that other scientist use the results to continue with the process, start with a new question, and, might be, to validate a theory or create a new one.
