Final answer:
The scientific method involves a sequence of steps beginning with observation, followed by hypothesis formulation, conducting experiments, and concluding. The correct loop of basic process in scientific practices is option 1: Observation, Hypothesis, Experiment, Conclusion.
Step-by-step explanation:
The loop of basic process in all scientific practices follows a sequence of systematic steps known as the scientific method. These steps usually include:
- Making observations.
- Formulating a hypothesis based on those observations.
- Testing the hypothesis through carefully designed experiments.
- Analyzing the data and drawing conclusions.
Using this information to address the student's question, the correct sequence is Observation, Hypothesis, Experiment, Conclusion, which corresponds to option 1).
