This project tested which household liquid cleans pennies the best. Pennies were soaked in different liquids and compared to see which one made them the shiniest. Lime juice cleaned the pennies the best.
The project appears to be something you care so much about and this is evident in your presentation. The ability to communicate your ideas effectively makes your work standout. Your idea is testable and we look forward to seeing cleaner pennies.
Great job on your penny experiment. I like how you tested your ideas carefully and learned that lime juice cleaned the penny best. Next time, adding pictures of the shiny pennies or finding a way to measure their shininess could make your results even stronger.
Nice work!
Thank you for the effort you put into this project. You did a nice job comparing different household liquids to see which one cleaned pennies the best. Your testing and results were clearly presented. Nice work.
Great!
