Planting and growing beans in our preschool window

Planting and growing beans in our preschool window

With all the bean measuring and play going on, we also took the time to explore how beans grow…

This was a simple way to plant a bean. We started with cotton balls, water, plastic baggies, and a bowl of water…

Each child dipped their cotton balls into water and placed them in their baggie. They used enough cotton balls to fill all the way across the bottom of the baggie…

Next each child added some lima beans to their baggie. They wanted to add handfuls so we had to remind them that the beans needed space to grow so only add four or five…

Before introducing this activity to the children, I had previously soaked the lima beans overnight to speed up the growing process a bit…

Once the children finished adding their cotton balls and beans to their baggies, we then closed up the zipper and taped them to our window (make sure the baggies are sealed tight so they hold in the moisture). Now all we have to do is wait and see what happens. We will talk about the growth of the beans as they start to shoot out some sprouts…

I think we added too much water in a few of our plants – or we didn’t seal them tightly enough or perhaps we got too carried away with the number of beans in the bag. In any case, we had a few that didn’t grow. So we are going to try again next week for those who would like to do it again. The interesting thing is that we were able to talk about why some didn’t grow as well as why we think some did. Great science discussions based on natural happenings in our classroom!

This one didn't grow....Time for a Do-Over!!

    We’ve currently got carrot tops growing on our window sill which my 6yo thinks is enthralling. Will have to give the beans a go as I think she would love them too.

      How did you grow the carrot tops?

    Sometimes I just browse through your site for gentle reminders of activities to do in my Kindergarten classroom. Thanks

    Do you ever have a problem with mold? When I’ve used a paper towel for this activity it seems like my seeds always go moldy . . . . Any suggestions?

    • Deborah J. Stewart, M.Ed. Posted September 18, 2011 11:43 pm

      Yep – they will mold if you get them too wet and if they sit too long. We just have to throw them away:) One thing I would suggest is to take photos or have the children draw the plants as they grow so you have something to keep as an alternative to moldy plants:)

    I love this Deborah. Have you seen ‘living walls’? Wouldn’t it be cool to find a fast sprouting plant that would eventually turn into a wall feature! Shar

      Haha – no I haven’t seen that – but would love to!

    What a great way to teach children how to plant from seed!

    I love the bag on the window with their names on it. So cool!

    Thanks for sharing this visual example!

    When is the best time to do this project with the lima beans?

    • Deborah J. Stewart, M.Ed. Posted March 4, 2017 5:38 pm

      This works well all year round!
