|Many common vegetables are vascular plants.
Use produce to observe the vascular system in action.
- Two glass jars or beakers
- Food coloring (blue)
- Celery stalks
- Lettuce leaves
- Magnifying glass
- Metric ruler
- Stirring stick
- Fill each beaker with water to a height of 2
centimeters. Use the crayon to mark the water level on the
outside of the glass.
- Add a few drops of food coloring to each beaker. Stir.
- Place a celery stalk in one beaker, flowering leaf end
- Place a lettuce leaf in the other.
- Observe the water level over a day or two. Then, use the
magnifying glass to observe the celery and lettuce.
- Consider the vascular structure of the celery and the
lettuce. The blue food coloring should reveal the plant's
network of veins.
- How long did it take for the plant to absorb the water?
- Extension Ideas
- Try the procedure with a non-vascular plant, such as
moss or fern.
