GOAL: Teaching the concept of transpiration!
- White Flowers/Celery
- Food coloring
1. Fill each jar with equal amounts water and add food coloring to each jar
2. Add the flower(s) and record down observations
3. Leave overnight and observe flower change in color the next day by observing the petal colors
This is the process of transpiration. The xylem in the plant suck up water like a straw and the colored water moves throughout the flower. Discover the capillaries in the plant once they are colored!
