The steps of the scientific method compliment the steps in the universal systems model
true or false

The answer for this would be TRUE. While in the scientific method, we implement the following steps: Observation, formulate a question, hypothesis, experimentation, analysis, and conclusion; the universal systems model includes the following steps: output, process, input and feedback. What makes these two compliment is that, both are the same when it comes to reaching the outcome of something that is being tested.

Student 1’s methods would be more accurate, because the student would control more factors. Only one variable at a time (either temperature or acidity) would be tested on each group of worms. On the other hand, Student 2 is testing both factors on all the worms, which could make the results unclear.
