First Grade Science Science projects: Plants and Water
Safety Issues

Young children should not use a knife. 

Material Availability

Readily available or easily purchased at the grocery store 

Approximate Time Required to Complete the Project

Overnight to collect the data; one day to prepare the science fair display 

To learn how plants transport water from their roots to their leaves 

  • Tall clear glass
  • Red food coloring
  • Spoon
  • Celery stalk
  • Knife 

Plants need water to grow. Plants transport water from their roots to their leaves through tubes called xylem.  


Xylem: tubes that transport water inside plants  


Plants need water. Water is transported through the plant through xylem tubes. 

Research Questions

How does water get from the roots of a plant to its leaves? 

  1. Gather the necessary materials. 
  2. Fill the glass about halfway with water.
  3. Add a few drops of food coloring to the water and stir.
  4. Have an adult cut the bottom of the celery stalk straight across leaving the leaves attached to the stalk.
  5. Place the celery stalk in the glass, cut end first. Set the glass somewhere where it will not be disturbed overnight.
  6. The next day, record any changes.
