There are three main types of corn kernels, but only one type produces popcorn. The design of the popcorn kernels is what allows it to pop. Inside each kernel there is a seed for a new corn plant, water, and starch (food for the seed during germination)  moisture turns to steam and pops the kernel. When the kernel is heated the water undergoes a phase change and turns into steam which increases the pressure inside the kernel. With increased pressure the kernel explodes and turns itself inside out.

You can find patterns in popcorn in flavors or prices when at the store. You can also have a hard time finding patterns when looking at the shapes since they all pop differently. You can find a pattern in the time it takes for them to pop-- while they might all pop at different times, you could still say "I know it takes about __ seconds for popcorn to pop." Or patterns in what it takes to pop.

We can explore the popcorn production process from growing corn to placement in stores, for what it’s like for different people. We can compare health and enjoyment opinions for dentists, health experts/nutritionists, parents, and snackers. We can explore different preferences of flavorings and toppings, hopefully with why. Ideally, we might find trends or patterns in those preferences. Also, we can consider opinions from people like workers who clean movie theaters. In addition, when creative writing, we can go out of the box to think about how microwaves feel about the volatile popping job... In ELAR, we can investigate text that we read and concepts to write about, and we need to delve into point of view per standards.

Popcorn balls (popped kernels stuck together with a sugary "glue") were hugely popular around the turn of the 20th century, but their popularity has since waned. Popcorn balls are still served in some places as a traditional Halloween treat. Cracker Jack is a popular, commercially produced candy that consists of peanuts mixed in with caremel-covered popcorn. Kettle corn is a variation of normal popcorn, cooked with white sugar and salt, traditionally in a large copper kettle. Once reserved for specialty shops and county fairs, kettle corn has recently become popular, especially in the microwave popcorn market. The popcorn maker is a relatively new home appliance, and its popularity is increasing because it offers the opportunity to add flavors of the consumer's own choice and to choose healthy-eating popcorn styles I wonder how popcorn will change in the future?

People prefer different varieties of popcorn for many different reasons. Some people like it with butter while others eat it plain; no salt, no butter, or any combination thereof. It's important to consider another person's perspective because everyone has different health considerations. A person who eats popcorn without butter might be vegan, or a person who eats popcorn without salt might have high blood pressure. When one looks at popcorn and its consumers through a different lens, one can gain understanding about an individual's choices, even broaden their own perspective on eating popcorn. For example, maybe they've never tried popcorn with M&Ms--truly a choice worth experiencing!

Popcorn appears to be a staple for thousands of years. There has been change in what we put on it and in some ways how we eat it. I would suppose the reason for this is the advancement of our palate - first pepper, then salt, and today all sorts of stuff! Yet as we evolved, the WAY we cook it proved to be far more interesting in how that changed over time.

Popcorn, also known as popping corn, is a special variety of corn . Each kernel contains a tiny drop of water. When it is heated, the water expands causing the kernel to explode and flip inside out. This can then be eaten different ways.

Popcorn’s details can vary based off the brand or type of popcorn you have. Some popcorn is sweet (kettle corn) salty (maybe it has your favorite flavoring salt), and buttery (movie theater). Hopefully it isn’t burnt..because now your home is filled with the strong smell of burnt popcorn.  It can be be fluffy, or it could just be the hard kernel. Popcorn can be sticky too! (Caramel)

Popcorn is a specific type of corn (one of 6 types)

The outer “shell” is called the hull. The endosperm inside the hull has a 14-20% moisture content, which is needed to “pop” effectively. When the kernel is heated, this moisture causes steam to build up and the kernel expands and cracks its hull.  The kernel expands anywhere from 20 to 50 times its original size.  The kernel must get to an internal temperature of at least 356 degrees and an internal pressure of 135 psi in order to pop.  A popped kernel of popcorn is called a flake.

# data[].attributes.body
Popcorn kernels are made up of 3 main parts: the germ, endosperm, and pericarp or hull.

While the hull is typically white or yellow, it can be red, black, or a variety of other colors.

One cup of air-popped popcorn contains 31 calories, 1 gram of protein, 6 grams of carbohydrates, 1 gram of fiber, and a trace of fat.

At first glance, the topic of popcorn is seemingly innocent and any sort of ethical ideas or debates of such topic seems to be outlandish at best. However, after delving further it became apparent that in years past a particular ingredient, diacetyl, has come under fire. Present in microwave popcorn, this additive was responsible for the over the top buttery flavor. However, it was also responsible for multiple cases of ‘popcorn lung’ in popcorn factory workers, consumers, and those exposed to the vapors. After several lawsuits the additive was removed and new substitutes took its place. The substitutes are no better/healthier than the initial ingredient and are still present in current microwavable popcorn. This begs the question of why use an additive at all? Isn’t there a healthier alternative? Is there a means by which we can further regulate the substances used not only in popcorn but other foods? What other things are we ingesting that are harmful to our bodies? For me this research further solidifies not only my thinking that air-popped is substantially healthier but also my dislike for popcorn in general.

According to the USDA:
Corn can be considered either a grain or a vegetable, based on when it is harvested. Corn that is harvested when fully mature and dry is considered a grain.  Popcorn is harvested when mature, so it is considered to be a whole grain.

Popcorn can be eaten all year long, at your home and/or at events. Though popcorn itself has been consistent, the amount of popcorn consumed has changed over the decades. In the 70's roughly 350,000,000 pounds of popcorn was sold...in 2018 it increased to roughly 1,000,000,000 pounds. All in all popcorn is an inexpensive snack.

I believe that the changes over time in regards to popcorn are evident and interesting to discuss. There has been changes from how it is made to how it is prepared or cooked.

We also know that the way it is cultivated has changes from being organic, and being made from GMOs or other unethical ways.

I love popcorn, so I had to think deeper about what could be right or wrong with it.

Some popcorns can include unhealthy ingredients, such as the type of butter being used, that can be harmful to those consuming it. It can be bad to consume this type of popcorn in large amounts. Some could say that there are healthier types of popcorn that have healthier ingredients and butter(s), but lack in taste.

Also, it seems wrong to eat popcorn outside of an “entertainment” setting, such as when watching a movie or playing a game. Popcorn is not a substitute for a meal, although some could have it be.

You also can also have patterns of popped versus un-popped popcorn.
