Gemstone polishing experience

For your summer vacation independent research project, how about trying a gemstone polishing experience? When you think of gemstones, you probably picture something sparkly, but in fact, raw gemstones have rough surfaces and look like ordinary stones.
However, by polishing them, they begin to shine brilliantly.
Start by flattening the surface with a file, then use polishing papers in order from coarse to fine.
Apply a finishing powder and polish, and finally rinse it clean with water—that’s it! Compare the rough stone before and after polishing, and take photos of each polishing stage to compile into your report.
In conclusion
I’d be happy if you can find an interesting topic—one that your teacher will praise—among the various themes.
In your 3rd-grade science independent study, try observing the nature around you and doing simple experiments to feel the joy of discovery.
Be sure to tell your friends and family what you learned.
By working on science self-study topics that interest you, your curiosity about nature and science will grow even more.
