Growing beans in a bag

An experiment to explore germination

Jessica Hug | April 2020

To grow beans in a bag is an experiment that helps children understand germination. It's easy to do, and the children will enjoy it.

Instructions

1. Place several damp, folded paper towels into a zip lock bag. Insert five staples about halfway up the bag. This will keep the beans in the right place so that there's room to watch the roots grow.

A few days later: the stems start to push upward.

After ten days the leaves begin to peek out of the seed coat.

Two weeks: the first true leaves appear while the stem continues to grow and grow!
