Vascular Plant Circulation Experiment

10:00 AM

color changing plant experiment

This unit in Science, we are studying plants, their parts, grouping, growth etc. The other day Jordan and I were discussing the roots and stem of a plant and how they help with the plant's circulation system and transferring water or nutrients to each part of the plant. To help show him this, we did a little experiment. This vascular plan circulation experiment consisted of placing some carnations in different cups of water colored with food coloring and watching them change color as the plant stem transferred the colored water to different parts of the plant. It was a ton of fun and really helped show him how the system of a plant works.

Carnations when first placed in the colored water. No change.

Carnations after about 30 minutes in the colored water. The color begins to change. 

After sitting in water overnight. 

Let me know if you have tried this experiment before. What colors did you use and how did it work for you?
