Germinating seeds in a bag is a fun way for kids to view how seeds transform into plants right before their eyes. Seeds don’t need soil to start germinating, so you can place them in a sunny window and they will start sprouting right away. This allows kids to watch how seeds sprout, which is a process normally hidden by dirt. There is a lot to learn in this experiment, yet it is so simple to do! As long as you have dried beans and some plastic bags, you can make these seed germinating bags.
Materials Needed for the Germinating Seeds in a Bag Experiment:
Fava Broad Windsor Seeds, 20 Premium Heirloom Seeds
You don’t have to purchase sees specifically for planting for this experiment. We used beans sold in the grocery store for human consumption for our seeds in a bag, and they sprouted right up with any problems at all!
Before starting the experiment, soak your bean seeds overnight in water. This will sort of “wake up” the seeds and get them ready to germinate. You’ll get faster results if you pre-soak your bean seeds this way. Drain the seeds before placing them in the bag.
Dampen a paper towel and fold it into the bag.
Place the seeds along one side of the bag, pressing them against the paper towel. Seal the bag tightly, and hang in a window using tape.
Make sure the beans are visible on the side of the window where the kids will be observing their seeds sprout.
Wait 24 hours. You should be able to see the seeds start to pop open and sprout after this time.
Within 3 days to a week, you’ll have fully sprouted seeds!
In a few more days, you’ll see the leaves start to emerge.
At this point, your beans are ready to move to soil. Plant them in a rainboot garden, or another small planter and watch them continue to grow!

can you use pinto beans?
Kim Staten says
I have not tried it, but any fresh beans should work. I cannot vouch for the quality of the experiment with dried beans.
Martha Prado says
Dried pinto beans work GREAT! That’s what I use for my Kindergarten class every year!!
Martha Prado says
Also, I only put 3 or 4 dried beans in the bag. (Too many make it complicated to follow each root, etc.) Most pinto beans will germinate, and you do NOT need to soak them over night! They will germinate in 2 to 3 days. Be sure to warn your children not to press or squish the soft beans (seeds), because they will become very fragile as they start to germinate and sprout. This is one of my all-time favorite activities! We all get super excited to see the “magic” of life!!
Paul Daniels says
What about pepper seeds? We put those in a bag with a wet paper towel seven days ago with no luck.
Kim Staten says
I can only confirm what we tried. 🙂
Angela says
I have had pepper seeds grow wonderfully in kindergarten but in soil.
Lacy says
My son’s class used mason jars instead of baggies, but his pepper seeds have successfully sprouted. It probably took close to a week before we saw activity. We are hoping to transfer them to soil and see if they survive Mommy’s black thumb. 😉
Kim Staten says
Very cool!
Micah-Amir's Mommy says
The peppers may take longer to grow. We planted some strawberry seeds on Earth Day and it just started to grow.
Mayrili C Garrison says
Just curious, because I’m sure my child will want to keep his beans alive, does anyone know how to properly transfer these to soil after?
Kim Staten says
In this activity we have only grown the beans in the bag and thrown them away afterward. You could try to separate them and continue to grow them in small pots. In which case, you would want to bury the bean and roots and let the sprout stay above the dirt. Let us know how it goes!
Beth says
Do you need to keep paper towel damp all days? What if it dries out ?
Kim Staten says
The towel should stay damp inside your bag. We’ve been doing it again and have had the towel in the bag for 7 days and I can visible see water droplets from across the room. 🙂
Teri says
Doing this experiment during remote learning with my 4th grade students. Some are reporting ‘smelly beans’. Is this normal? Honestly, sometimes life is smelly!
Kim Staten says
I’m imagining that they are opening their ziploc bag…lol! We have had our newest attempt at this experiment hanging from our dishwasher for a month and I can’t smell anything, but the original seeds look mushy in the bag, so they probably would smell if we opened the bag.
Mary Arney says
Yes, pinto beans. Kidney bean did not sprout at all, lima bean maybe will sprout, but pinto bean ready to plant (I think).
Vi says
Hi! I’m wondering what type of soil to put them in after they sprout? We did this experiment and they’re sprouting super quick! & should I continue to leave them in the window? 🙂
Kim Staten says
I honestly have never tried to plant them after this experiment. You could try putting them in a pot and see what happens!
Janet Rodriguez says
What about apple seeds? Would that work?
Kim Staten says
I don’t think that apple seeds would work the same, but you can always test it out. Or do two kinds of seeds and compare the results! Let us know how it goes!
Ale says
Once I put it in soil how much water should I put? And how many times?
Kim Staten says
I would suggest Googling how to transplant beans to the garden since I am very much not a gardening expert. 🙂
