Think about the experiment that student created to prove that electromagnetic induction exists. Write an evaluation of this plan. How would you summarize it? Did they include all of the parts of the experimental design (testable question, independent variables, hypothesis, and the setup)? What do you think of this plan? What questions do you have about the investigation? Do you think that this investigation would prove to the person that electromagnetic induction exists? Why or why not?
Sample answer: The student's created a plan to learn about electromagnetic induction. They included a testable question, a hypothesis, and the setup has enough details to help someone recreate the experiment on their own. However, the experiment is missing the independent and dependent variables. The independent variable is the movement of the magnet, and the dependent variable is the change in voltage. I think that this experiment would prove to someone that electromagnetism exists because they can clearly see that as the magnet moves, voltage is created.

How I Can Learn More
K: I know that electromagnetic induction is the process of generating electric current using a magnetic field.
W: I want to know more about how electromagnetic induction can be applied in real-life situations and how it is used in technologies like generators and transformers.
L: I learned that the student's experiment plan was well-structured with a clear testable question, hypothesis, and setup. However, they were missing the independent and dependent variables.
H: To learn more about electromagnetic induction, I can conduct further research on its applications in different technologies and industries. I can also explore more experiments related to electromagnetic induction to deepen my understanding of the concept.
