Drying an ear of corn: Purchase a fresh ear of corn in its husk. Peel back the husk but do not tear if off the ear. Tie a string under the husk right below the stem. Hang the ear on the string in a sunny window. Every week or two have the children stick one of the corn kernels with a toothpick to see how much moisture is in the kernel. Eventually the amount of moisture will decrease and the ear will be dry. Watching this process helps the children learn that water is lost to heat. To do this in the Scientific Method format see Everyday Discoveries, page 91.
