Question 52

Analyze the experimental design to ensure it is a valid test of the law, and then repeat the valid test

The student's next step should be to analyze the experimental design to ensure it is a valid test of the law of conservation of mass and then repeat the valid test. This approach allows the student to identify any potential errors or factors that may have led to the discrepancy in the mass observed.

A) Change the results so that they agree with the law of conservation of mass

This option is incorrect because manipulating results to fit a theory undermines the scientific method. The student should not alter data but rather seek to understand the causes of the observed discrepancy through proper analysis and experimentation.

B) Ignore the law of conservation of matter, as it does not apply in this situation

Ignoring the law of conservation of matter is not a valid scientific approach. The law is a fundamental principle in science and should not be disregarded; instead, the student should investigate why the results seem inconsistent with this law.

C) Analyze the experimental design to ensure it is a valid test of the law, and then repeat the valid test

This option is correct as it embodies the essence of the scientific method. By analyzing the experimental design, the student can ensure all variables were controlled and that the experiment was conducted properly, leading to a more accurate understanding of the conservation of mass in their experiments.

D) Discard the law of conservation of matter because this experiment proves it is wrong

This choice is incorrect as it suggests rejecting a well-established scientific principle based on a single experiment. The student should not dismiss the law of conservation of matter but rather investigate the experimental setup to find a resolution to the discrepancy.

Conclusion

The correct answer is option C, as it emphasizes the importance of analyzing and validating the experimental design in light of the law of conservation of mass. Options A, B, and D offer flawed approaches that disregard the scientific method and the validity of established scientific laws, while option C promotes a systematic and rational investigation to resolve the observed inconsistency.
