What explains the result?
Colored water traces movement in xylem; leaf transpiration and narrow vessels help pull water upward.
LIFE SCIENCE · GRADES 4–8
INVESTIGATION QUESTIONHow does water temperature change the time colored water takes to reach the leaves?
Prepare matched temperature conditions. Use one stalk per labeled temperature and start all three together.
Colored water traces movement in xylem; leaf transpiration and narrow vessels help pull water upward.
Xylem transport explains water movement in plants and informs irrigation studies.
Illustrative times are not predictions; stalk size, freshness, leaf area, light, dye, and water temperature affect travel. A cut stalk has no roots.
DEDICATED CELERY TRANSPORT INVESTIGATION · GRADES 2–7
Compare how cold, room-temperature and comfortably warm water affect the real time colored water takes to reach celery leaves.
ONE TEMPERATURE PER MATCHED STALK
To compare fairly, prepare a fresh similar stalk for each bath. Keep cup volume, dye drops, light and stalk size consistent. The animation only illustrates a possible pattern.
SPECIMEN JOURNAL
SCIENCE CONNECTION: Xylem vessels move water and dissolved minerals from roots toward leaves. Leaf evaporation helps pull water through a plant. A cut celery stalk is a simplified tracer model, not a rooted plant.
