Easy science project for kids: How to grow a Lima bean seed

Posted on

School science projects can be an exciting time for students who like to explore the wonders of nature. For children, it is a great time to explain the many natural processes that occur around us. A very simple science project to begin with is the process of growing a Lima bean seed.

Lima bean seeds are easy to grow and resilient to climate changes. They have a fast growing rate: most beans will sprout in about 14 days. If you’re planning on performing this science project, please be aware of the time it takes to complete the project and the deadline of the science project.

Lima bean seeds are also called ‘butter beans’. It is believed that Lima beans or Phaseolus lunatus originated in South America around 2000 BC. By 800 AD, Lima beans were exported to different parts of Europe and America. Lima bean seeds have a characteristic kidney-liked shape. They are about 1-3 cm long and are usually white. As legumes, Lima beans provide good fiber content and other nutritional minerals.

In this project, you’ll learn how to start the growth of a Lima bean seed and monitor its process.

  • Select 3-4 Lima bean seeds. Set aside. Tip: avoid selecting more than 4 beans to allow roots to grow. 
  • Use adhesive tape to cover a small section of the jar with dark colored paper. Tip: if not testing for light and dark growth, then skip this section. 
  • Use dry paper towel and insert into the jar.
  • Insert the beans one a time. Try to spread the beans throughout the jar. Make sure to add 2 beans to the dark part of the jar and 2 beans to the light side of the jar.
  • Spray the paper towel with water. Avoid soaking the paper towel. Tip: To retain moisture in the jar, slightly cover the top of the jar with plastic wrap.
  • Place on a sunny area but avoid excessive heat or cold.
  • Water every day.

Monitor the growth of the Lima bean:

The most amazing part of growing any plant is to display them. Once the science project is done, you can plant them into potting soil.
