Here is some information that you may find useful for a science fair project about popcorn.
Some brands of popcorn give you more yield than others. Find out for yourself which brand pops the most kernels. When you tell your family and friends which is the best they will just love it. You will also learn how temperature affects popping.
Many years before there were movies, there was popcorn. Archaeologists have found 80,000-year-old corn pollen below Mexico City. Because this pollen is almost exactly the same as modern popcorn pollen, researchers believe that "cave people" most likely had popcorn.
It is believed that popcorn probably grew first in Mexico, though it was also used in China and India hundreds of years before Columbus reached the Americas. The oldest popcorn ever found was discovered in the "Bat Cave" of central New Mexico. It is thought to be about 5,600 years old. In tombs in Peru, archaeologists found ancient kernels of popcorn that are so well preserved that they can still pop.
Conditions can preserve ancient popcorn so perfectly that it still looks fluffy and white when the dust is blown off of it. In a cave in southern Utah, researchers found surprisingly fresh-looking 1,000-year-old popcorn.
Popcorn was probably an important part of life in the ancient Americas. On a 1,700-year-old painted funeral urn found in Mexico, a corn god is shown wearing a headdress of popcorn. Decorated popcorn poppers from around the same time have been found in Peru.
Some Europeans learned about popcorn from Native Americans. When Cortes invaded Mexico and when Columbus arrived in the West Indies, each saw natives eating popcorn as well as using it in necklaces and headdresses.
Native Americans brought a bag of popped corn to the first Thanksgiving. A common way to eat popcorn at that time was to hold an oiled ear on a stick over the fire, then chew the popped kernels off it. Natives throughout the Americas also made a popcorn beer. Some made popcorn soup.
After learning about the fluffy food, colonists began enjoying the first puffed breakfast cereal-a bowl of popcorn, served with cream or milk.
When sugar was rationed during the second world war, Americans changed their snacking habits and ate three times as much popcorn as they did before. Perhaps the favorite place to eat popcorn was at the movies. When television took off in the 1950s, popcorn sales dropped for a while.
The average American eats nearly 70 quarts of popcorn a year. But the United States isn't just a land of popcorn lovers, it's also the land of popcorn. Most of the world now gets its popcorn from Nebraska and Indiana.
Like other seeds, it has a tiny plant embryo inside (a life form in its earliest phase). The embryo is surrounded by soft, starchy material that will give the embryo energy for growing into a plant. A hard, glossy shell protects the outside of the seed.
When the kernel is heated to a high temperature, (400 degrees F), the water inside the kernel turns into steam. The pressure from the steam causes the kernel to explode. The soft starch inside bursts out at about 40 times its original size, turning the kernel inside out. This creates the fluffy white area of a popped kernel.
Popcorn kernels contains about 14 percent moisture. If the popcorn is much drier than that, it will not pop. Popcorn kernels should be kept in a tightly sealed jar so as not to dry out.
Native American tribes tells of spirits who live inside each kernel of popcorn. The spirits are quiet and content to live on their own -- but grow angry if their houses are heated. The hotter their homes become, the angrier they get -- shaking the kernels until the heat is too much. Finally they burst out of their homes and into the air as a disgruntled puff of steam.
Popcorn is both a small-seeded variety of field corn with kernels and a buttery, light snack that some people sometimes prefer over a heavy meal. There are two basic types of popcorn: pearl popcorn and rice popcorn. Rice popcorn, also known as hull-less popcorn, has pointed, white kernels. Pearl popcorn has yellow or orange rounded kernels.
