To arrive at this answer, let's break down the steps and see how they should be ordered:
1. Observation: The first step in the scientific method is to make an observation of a phenomena or gather information about a specific topic.
2. Hypothesis: Based on the observation, a hypothesis is formulated. A hypothesis is an educated guess or explanation that can be tested through experimentation or further observation.
3. Prediction: Once a hypothesis is formulated, scientists predict the outcomes that should occur if the hypothesis is correct. These predictions are usually based on logical reasoning and the existing knowledge about the subject.
4. Experimentation/Observation: In this step, scientists conduct experiments or make further observations to test the validity of the hypothesis and to gather data to support or refute it.
5. Hypothesis (revisited): After analyzing the data collected during experimentation or observation, scientists revisit the hypothesis and evaluate whether it is supported or refuted by the evidence. If necessary, a new hypothesis may be formulated based on the results.
Therefore, the correct sequence of steps is b. hypothesis - observation - prediction - hypothesis - observation.
