Process Journal
This page shows how my project changed after teacher feedback. It records the main questions, what I needed to improve, and the next steps I used to make the experiment more focused.
Main Feedback
At first my ideas were too broad. We discussed how the project needed one clear physics focus instead of jumping between too many topics.
My next step was to choose electromagnetism and connect it to a testable model: changing the coil and measuring how much metal it could lift.
The conference helped me move from just building a cool crane to actually collecting data. I needed variables that were realistic for a school project.
I focused on coil turns, current, core material, and contact area because those could be observed or tested with my materials.
I revised the explanation so it did not just say "the magnet gets stronger." I added the idea that current creates a magnetic field and that the iron core helps guide it.
I also connected the small prototype to real electromagnets in scrap yards, recycling, MRI machines, and maglev trains.
Action Plan
My project was more like a build idea. I knew I wanted a crane, but the physics question was not sharp enough yet.
I chose specific variables and planned how to compare electromagnet strength using washers and a digital scale.
The final project became more organized: research, circuit design, prototype photos, experimental results, and real-world applications all support the same main idea.
