The student investigation is lacking specific details, so it is challenging to identify all the missing aspects. However, based on the provided information, the following improvements could be suggested:
1. Experimental Design: The investigation lacks a clear experimental design and control of variables. The student should outline a detailed procedure, including the steps to be taken and the specific measurements to be recorded.
2. Hypothesis: The student should state a clear hypothesis that can be tested during the investigation. For example, "Increasing the number of rotations of the electric car's wheels around the iron core will enhance the strength of the electromagnet."
3. Quantitative Measurements: The investigation should include quantitative measurements to assess the strength of the electromagnet. Measuring the magnet's pull or the strength of the magnetic field would provide more concrete results.
4. Control Group: The student should establish a control group to compare the observed effects of running the electric car around the iron core. The control group would involve conducting the same experiment without running the electric car, ensuring that any changes in the electromagnet are attributed to the car's rotation.
5. Replicability: The student should replicate the experiment multiple times to ensure the reliability and validity of the results. Conducting the investigation in different conditions and with different samples of iron cores would help determine if the observed effects are consistent.
6. Data Collection and Analysis: The student should record and analyze the data collected during the investigation. This would involve plotting graphs, calculating averages, and looking for patterns or trends in the results.
7. Conclusion: The student should properly summarize their findings and draw conclusions based on the results obtained. Additionally, they could include any possible sources of error and suggestions for improvement in future investigations.
By addressing these missing aspects, the student's investigation will become more scientific, rigorous, and provide more meaningful results.
