Beans in a CD Case Experiment Begins

A friend suggested this idea of growing beans in a CD case, and I loved it immediately! Think of it as the world’s skinniest terrarium. My experiment is to see how long the plant can grow in this narrow environment. So far, so good, with wet potting mix soil, 3 seeds and a fat clear CD case. Check back as I will update the growth process. This would make a fun “living diagram” and students could use a paint pen to label the parts of the plant when it’s grown, before they transplant it into something larger.  The plan is to share this project with children in Haiti (I travel next week with Project Hope Art) so they can learn to add this nutritional food to their diet.

What a great idea.
Thanks for sharing.

What a fantastic idea! I'm pinning it to do later.

Love this!

This is brilliant! We did this years ago with plastic cups and paper towels -- but the CD case is even better!

I have also seen this done with the clear baseball card protector pages. I want to see how you label the parts. That sounds cool!

Great idea, love this!

Love it!

A (maybe) stupid question: how do you water the plants?

liz said...

I'd love to know of any updates. I'm planning this project for next week and I hope it works out!
thanks.

Marty said...

I too, would love to know of any updates.
And how DO you keep it watered?

Thanks!

Thanks for asking about updates. The plant did grow a little bit more, but then stopped. I suspect it was because I bought the seeds at a drug store, and fear that they were old or something. Watering was done by holding the case flat and just carefully opening the cover and pouring a bit of water on it.

I plan to try this again when I have a chance.

This is wonderful. I remember using plastic cups as a kid, but the CD case is too nifty. It'd be fun to make a disk of songs about gardening to give it all as a gift. Thanks for the inspiration!

I love this idea! I might see if it works with peas.

Miss Rachel said...

What kind of seeds did you use?

Kathy Barbro said...

Just a garden bean. But look around for little ones as my last test bean got too fat and kept popping the lid open as it grew! I'm thinking of trying grass just to keep that from happening again...

What if you put a wet paper towel in, as we've done in a plastic bag, instead of soil, so that the moisture from the towel keeps a balanced moisture for the seed? I'm going to try one now & see how long it takes to grow enough to see the plant parts. THANK YOU for this great idea, which I found on Pinterest.

I'm featuring this idea on one of my reviews for "The Tree That Bear Climbed" as an activity for preschoolers.

Don't know how to do a linkback so I'll just add it as a word link. =D

Thanks! Tina 'the book lady'

By doing this experiment kids will learn how seeds grow form a tree and also will enjoy doing this work.

Do you think this would be good for a science fair project and if so, how would you present it? Pictures?

Kathy Barbro said...

I think it would make a great science fair project, but I'm not an expert in that area. I bet if you did some experiments to find out exactly how long it took a seed to take root, you could plant several cases accordingly to show the real thing at the fair. I think the ability to label the real parts with a poster marker makes for a pretty cool display.
