Thirsty Celery

(Elementary)

What will students learn?

In this experiment, students will observe capillary action in celery, witnessing color absorption through its vascular system. As they explore transpiration, they'll also learn to identify xylem, enhancing their understanding of plant biology while practicing crucial scientific skills in observation and documentation.

What do you need?

  • Celery stalks (with leaves)

  • Clear glasses or cups

  • Water

  • Food coloring

  • knife

Steps:

  • Cut the bottom of the celery stalks to expose fresh cross-sections.

  • Fill glasses or cups with water.

  • Add a few drops of food coloring to each glass, using different colors for each.

  • Place a celery stalk in each glass, ensuring the cut end is submerged in the colored water.

  • Allow the celery to sit undisturbed for several hours or overnight.

  • Observe and record any changes in the celery stalks and leaves during this time.

  • Carefully cut the celery stems.

  • Examine the vascular system.

  • Identify and point out the xylem, the specialized plant tissue responsible for transporting water from the roots to the leaves.
