How to Grow Pinto Beans as a Science Project

Grow pinto beans with paper towels to germinate them so that you can plant them outdoors.

Growing pinto beans is an easy, quick way to demonstrate how seeds germinate and can make a great science project for a school science fair. The best part is that this project can be completed with items you probably already have at home. You and your child can probably put it together in about 72 hours. The project is sure to captivate your child and her classmates.

Soak the pinto beans in room temperature water for a few hours. This will stimulate the germination process.

Wet a paper towel and place it in a plastic bag. Add a couple of beans to the bag.

Store the bag in a cool, dark place. A kitchen cabinet is perfect.

Check on the bag each day, until the bean has sprouted.

Plant the sprout in a pot of soil. Place the pot in the sun and water the sprout as needed.

When the sprouts are about three inches high, plant them outside, if you desire. Space plants 15 inches apart, and water as needed. In three months, you can harvest them and have fresh-grown beans for your table.


Make up several baggies and place them in different locations with varying temperatures. See which environment causes the beans to sprout the fastest.

Document each phase of the process with photographs. Have your child keep a written log of what he does and what happens each day. Create a display board with the life cycle of the pinto bean.

You can substitute any type of dried bean for the pinto bean. Compare different types of beans for an experiment about which bean grows the fastest.
