Observations of Celery Color Experiment
Initial Setup:
- Cup 1: Contains celery with blue dye in the water.
- Cup 2: Contains celery with red dye in the water.
Time: 0 minutes
- Both cups are set up with celery sticks submerged in water with dye. The celery looks fresh and green at the top where the leaves are.
Time: 10 minutes
- Cup 1: The celery at the bottom is starting to show a light blue tint. The leaves still look mostly green but are beginning to appear slightly blue around the edges.
- Cup 2: The celery at the bottom is beginning to show a light red tint. The leaves still look green, but there are hints of red starting to show.
Time: 20 minutes
- Cup 1: The blue color is more pronounced, with the lower part of the celery turning dark blue. The leaves are now showing a more significant blue hue, especially at the tips.
- Cup 2: The red color is stronger now, with the lower part of the celery turning bright red. The leaves are also starting to turn a noticeable shade of red, especially along the edges.
Time: 30 minutes
- Cup 1: The entire celery stalk is now a vibrant blue color, and the leaves have taken on a rich blue shade. The blue dye has moved all the way up the celery, clearly showing the process of capillary action.
- Cup 2: The entire celery stalk is now a bright red. The leaves are a deep red color, and the red dye has traveled up the celery completely, similar to the blue in the other cup.
Overall Conclusions:
- Both cups demonstrated how the dye moved up through the celery stalk due to capillary action. Over the course of 30 minutes, the blue and red dyes significantly colored the celery, showing a clear transformation in both cups.
- The experiment successfully illustrated how plants absorb water (and the dye with it) through their stems.
Additional Thoughts:
- This was a fun and colorful project! It was interesting to see how quickly the colors spread and how different the results were, even though the experiment setup was the same.
