Corn Science


Grow corn in baggies! Have children put popcorn seeds in bag with a small handful of dirt — water. Tape on wall or on window — you will see corn growing!


This science activity involves buying dried corn on the cob, often sold as squirrel feed in stores like Wal-Mart. Allow the children to pick the kernels off the cob, a wonderful fine motor activity and use the resulting corn kernels in your texture table. The children will also enjoy painting with the leftover cobs in your art area. Extend this activity by saving a corn cob to grow in your science area. Fill a container (large enough to accommodate the corn cob) with 1 inch of water and allow the cob to soak for approximately 1 1/2 – 2 weeks (a clear, see-through container allows the greatest observation of growth and make sure to keep watering the corn cob). The cob will soon sprout plants that will grow very tall and can be planted in soil.


Corn Sensory Experience

In your science center place different tubs with:

Cornstarch

Cornmeal

Corn Kernels

Popcorn

Allow children to merely experience the different texture of each type of corn. Extend this activity later in the day by making cornstarch goop. Making cornmeal playdough. Popping popcorn. Make a math activity grow from this…Put out small paper cups and count how many spoonfuls of each type of corn it takes to fill one cup. Make a graph. Grow some corn in Ziploc baggies ( don’t zip them up! Plants need oxygen.) When the seedlings have grown plant a crop outside. Corn does not self-fertilize and so it is best to use real corn seeds rather than popcorn kernels.


By taking an ear of corn and submersing it into a tray of water, you can start a corn plant. We used and old ear that had been dried out. We also took a fresh ear and removed the kernels and submersed it. We compared the results of both as time went on and roots developed on the dried cob.
