Easy fall science: Sprouting Indian corn

Last fall, our family attended a harvest festival where my kids had the opportunity to go into a corn field and pick some Indian corn right off the stalk. We brought several ears of Indian corn home with us and used them for a few different projects.

During our seed unit, we had previously learned that corn kernels are seeds. So we decided to do an easy fall science activity that involved sprouting Indian corn to see what would grow!

But I’ll confess: the first time we tried to sprout the Indian corn, our ear of corn went moldy before it did much sprouting. On our second attempt, we changed how much water we used and got much better results. In fact, the way that worked for us is actually easier than our first plan. So this truly is an easy fall science activity!

Note: For more corn activities, see my Corn Unit Study page.

We laid the ear of corn into a container and added enough water to cover just the bottom 1/3 or so of the ear. (Note: adding more water may lead to too much mold growth and not enough sprouting.)

Then we waited. And of course, checked the water level every day or two and added more water as needed to keep the corn about 1/3 submerged.

About a week later, we had some very noticeable sprouts beginning to appear.

It was interesting to see that many of the sprouting kernels were actually beginning to come loose from the cob.

After another 10 days had passed, our cob was well sprouted with green shoots coming up from both sides of the cob where it had been exposed to water.

We still experienced some molding, but not as bad as our first attempt when we had used much more water.

Many of the kernels completely separated from the cob, and others became loose enough to pluck off. Here is a picture showing a kernel (aka, seed) with a sprout shooting out of it.

      We did not try to plant the corn afterwards, so I can’t say for sure what would have happened.

    We’ve done this for years and my kiddos love it each time. So interesting for them to watch the sprouts grow.

    Are these just the cobs that you buy random places in the fall? Just wondering if they’d be too old/dried out to work.

      We got the cobs freshly harvested from a local field at their fall harvest festival.

    DI’d you just leave out in a window or did you refrigerate? I wonder if regular sweet corn would work also?

      We just left it out. We did not refrigerate.
