Water is important for all living things. All living things contain water. Water is stored in cells.Like the human body, the carrot’s cells are filled with water.

Water can be removed from living things through a process called dehydration. In this science fair project, we will be dehydrating carrots to determine how much water they contain.


How much water is in a carrot?


  • Kitchen scale
  • Carrot
  • Knife
  • Cutting board
  • Wax paper
  • Lamp


  1. Gather the necessary materials.
  2. Wash the carrot and cut off the stem. Allow the carrot to dry completely.
  3. Weigh the carrot and record its weight.
  4. Weigh a small piece of wax paper and record its weight.
  5. Have an adult cut the carrot into 1/8-inch slices. Lay the slices on wax paper. Place the slices of carrot under a lamp.
  6. After two days, weigh the carrot on the wax paper. Subtract the weight of the wax paper. Record the information.
  7. After five days (another three days after the first two days), weigh the carrot on the wax paper again. Subtract the weight of the wax paper. Record the weight.
