Science for Kids ~ Starting Seeds ~ Bean Jars


This investigation is very simple but fascinating. Did you know you can grow a bean in a jar with just a little water?

What you need

  • A broad bean seed
  • Jar
  • Kitchen roll or a napkin
  • Water


  • Swirl a small amount of water around the jar.
  • Fold your napkin or kitchen roll and place in the jar. ( we made the kitchen roll very slightly damp also )
  • Place the bean seed in the jar resting on the napkin.
  • Spray some water on the bean every few days.

The bean should start to grow roots after a few days, this is called germination.

We kept one bean in the dark and one in the light, both germinated and grew into small bean plants. This shows that light is not necessary for germination.

You can see here that the plant grown in the dark is a slightly less green than the one grown in the light.

What amazes me the most is that all this can grow from one tiny seed with no additional nutrients other than those contained in the bean itself.

After a few days in the light the bean plant kept in the dark was as luscious a green colour as its counterpart.
