Observing and Recording data are big parts of being a good scientist. Another important step is Reporting that data to a scientific community. And guess what...that's what you just did. Good work, you ZOOMscientist, you!

In general, fruit juices and vinegar (and some sodas, too) are acids. It will take different amounts of different acids to turn the cabbage juice back to its original color. Also, some acids will polish a penny better than others.

You might notice that even though everyone did the same experiments, they didn't always get the exact same results. That's because each of you did your experiments in a different way. Maybe your cabbage juice was a slightly different shade than someone else's, or you used a more acidic brand of orange juice. There are lots of variables that could affect what you observed.

Yadda, Yadda, Yadda. GIMME MY PRIZE, you say! And here it is:
