PROBLEM: Can a plant grow from just the top of a carrot?
NOTE: YOU MUST START THIS PROJECT TONIGHT!
RESEARCH: What kind of root does a carrot have? Why is the root so big? What
is needed for a plant to grow?
HYPOTHESIS: Can the carrot top provide what is needed for the plant to grow?
- Cut about half an inch off the end of the carrot that has the leaves.
Cut the leaves off close to the base of the carrot.
- Put the carrots into the container with the cut side down.
- Add enough water to cover about half the carrot top.
- Place the container in a well-lighted window.
- Observe the carrot tops each day for any changes. Remember the changes
may start out small and change slowly. Look for new leaves and roots.
- Use a metric ruler to measure any growth you may observe.
- Continue your observations for six days and write your report on the
DATA: Make a chart to record any changes and measurements
CONCLUSION: This is not optional. You must explain what you learned by doing
this activity. Remember that you must answer the question you asked in your
original problem statement.
NOTE: BE SURE TO HAVE YOUR PARENT OR GUARDIAN SIGNS YOUR WORK.
PARENTS: YOUR SIGNATURE SHOWS YOUR STUDENT HAS DONE THE WORK.
POSSIBLE HYPOTHESIS: No growth will occur since the carrot is not living. OR Leaves will grow since even this small part of the plant is still living.
POSSIBLE CONCLUSION: The carrot top should show some new growth each day. The student should discuss the possible reasons for the growth.
