Title: Grow an Avocado Tree - Seed Germination Experiment

Objective: To explore the process of seed germination and observe the growth of an avocado tree.


  • An avocado pit (seed)
  • Toothpicks
  • Glass or jar
  • Water
  • Optional: Notebook or journal for recording observations and measurements


  1. Carefully remove the pit (seed) from a ripe avocado. Rinse off any remaining fruit flesh and dry the pit with a paper towel.
  2. Locate the wider, rounded end of the pit (this will be the bottom) and the narrower, pointed end (top).
  3. Insert four toothpicks around the middle section of the pit, evenly spaced apart. Place them in a way that allows the pit to be suspended partially in water without fully submerging it.
  4. Fill a glass or jar with water until it reaches about one inch (2.5 cm) in depth.
  5. Gently place the avocado pit on the toothpicks, ensuring that the bottom (wider end) is submerged in the water while the top (narrower end) remains exposed.
  6. Find a suitable location for the setup, ideally with indirect sunlight and consistent room temperature.
  7. Observe the pit daily and ensure that the water level remains constant. Add water as needed to maintain the same level.
  8. Record your observations in a notebook or journal. Include details such as the date, changes in the pit, and any other relevant observations.
  9. Over time, you will start to notice the development of roots and a stem emerging from the avocado pit. This process may take several weeks.
  10. Continue monitoring the growth of the avocado tree. Observe changes in root length, stem development, and any leaves that appear.
  11. Optional: Measure the height of the stem and the length of the roots at regular intervals to track the growth progress.
  12. Discuss the findings and encourage kids to reflect on the process of seed germination, the role of water and sunlight, and the growth of a new plant from a seed.

Safety Considerations:

  • Ensure careful handling of the avocado pit to avoid injury.
  • Adult supervision may be needed, especially when handling sharp toothpicks or if using sharp tools to measure growth.

This experiment allows kids to witness the process of seed germination and observe the growth of an avocado tree. It promotes curiosity, patience, and an understanding of plant life cycles. Enjoy the journey of growing your own avocado tree and exploring the wonders of nature.
