This article is about the experiment that we did with celery. The class rated the celery on a scale from 1 to 5, 1 being the best freshness and 5 being the worst. Below is our information in a table.
# | control | blue | red | | 1 | 4.5 | 22.7 | 9.1 | | 2 | 40.9 | 9.1 | 9.1 | | 3 | 18.2 | 22.7 | 18.2 | | 4 | 18.2 | 18.2 | 36.4 | | 5 | 18.2 | 27.3 | 27.3 |
#= freshness scale. Numbers are the percent of students who voted for that freshness. For example, 4.5% of the students thought their control celery should be rated a freshness of 1, while 22.7% thought the blue celery rated a 1, and 9.1% thought the red celery rated a 1. Below is the same information in a triple bar graph. 
As you can see, the celery in red food coloring seems to rot faster, but the celery in blue food coloring and water seems to stay fresher. Our class thinks that food coloring does affect celery freshness. Red food coloring is bad for celery while blue food coloring keeps celery a little fresher. This is a great experiment to do with your class or by yourself. If you try it, please send us your results.
