In evaluating the sensor experiment

In evaluating the sensor experiment scheme, special attention should be paid to the failure of the experiment as the sole criterion for evaluation.For the successful experimental scheme, it is necessary to start from whether the experiment can achieve the purpose of the experiment and whether the data results are within a reasonable margin of error, and whether the experimental report produced by the second student can reflect the student's understanding of the principle of the experiment.For unsuccessful experimental programs, students should be allowed to reflect and appropriately assisted, and a second evaluation should be redesigned.
