How do I graph my Cleaning Pennies Science Fair project?

Question

My science fair project is "Which acid best cleans pennies?" And I am testing vinegar, lemon juice, and Coca Cola. How do I graph my results and what type of graph should I use?

Answer 1

The real question is how to get the data. A cheap point and shoot camera could be used to get image data for all the pennies at the same time, under identical lighting. On a computer, the red, green and blue values could be averaged for a brightness, or they could be plotted independently. It's mostly red, right?



Then it's just brightness vs. time.

placed pennies in vinegar, like 10 diverse samples. Take each and each out after a minute, and inspect the outcomes Do it lower back yet by potential of actual rubbing them to scrub it Graph cleanliness by potential of time
