Everyone knows that popcorn is a delicious snack, but it is also a fascinating food, a great theme for your science fair and school projects. Please check these sections for useful information.
For centuries people have been fascinated by popcorn. Native Americans believe that spiritual lives live in every corner of popcorn. When heated, the spirit became angry, eventually jumping out of the house and being blown into the air as unsatisfactory steam. An attractive but not scientific explanation of the reason popcorn pops
Popcorn is scientifically known as Zea mays everta. It is corn or maize and is a member of the grass family. Popcorn is a whole grain consisting of three elements: germ, endosperm, leather (or shell). The four most common types of corn - sweet, sunky (aka field), vermiculite (aka Indian corn), popcorn only popcorn! Popcorn differs from other kinds of cones in that the thickness of the outer skin makes it possible for it to rupture.
Each popcorn contains a small amount of water and it is in soft starch. Popcorn needs 13.5 - 14% moisture to become popular. Soft starch is surrounded by hard exterior
When the core is heated, the water begins to expand. At about 212 degrees, the water turns into water vapor, and the starch of each core turns into a goose like super gel. The core keeps heating up to about 347 degrees. The grain pressure will reach 135 pounds per square inch before the last ship's blast
An explosion releases the steam inside the reactor core. Soft starch in popcorn overflows and overflows, it quickly cools, it becomes a strange shape we know well and love. The kernel is extended to 40 to 50 times the original size.
You can try a lot of experiments with popcorn. First of all, we need to compare what we measure and what to measure. For example,
When you decide what you want to see, start thinking about the questions you want to ask and answer. For example,
Since it is a subjective problem that is difficult to measure, avoid problems such as "which brand is the most suitable"
Be sure to copy the experiment. It is important to repeat the test at least three times. In other words, comparing the number of microwave popcorn and undeveloped core, we need to test three different packages for each brand. Of course, this is a lot of popcorn, but that's only meaning that you can eat lots of popcorn. Getting better: Experiment in a few days after planning in advance
If there is a dollar every time I ask this question, we are very rich. Every time we answer it we are very poor if we have a dollar.
First of all, we do not mention the brand. You may have your favorite popcorn brand, but we do not have it. I like America made popcorn. But we appreciate being a science fair project, you want a quick answer, it brings us a second point: this is your science fair project. The bad news is that there is no quick answer. The good news is that you ate a lot of popcorn on the way.
This event is not suitable for use as a science fair project. A good science fairness project will focus more attention on control variables and accurately measure and analyze the data. To find the perfect Science Fair project for yourself, check the creative library for over 1,150 Science Fair projects or use the theme selection wizard to obtain individual project proposals.
There is no better way to learn than the actual application of the science fair project. Students who participate in the science fair are given important life skills: The Science Fair provides presentation skills to students, stimulates confidence and belief, research-led exploration ability gives passion to competition, Open the door to infinite possibilities. As a graduate of the Science and Technology Expo, as a judge, as a volunteer, as a teacher, as a student to participate in the science fair for the first time, as a supporter of science, we know the importance of science and all science fields I will. We have saved our lives and the lives of the people we love with new renewable energy development and biomedical progress. We believe that it will be a better place for all of us to join the world, prosper across the border and create new technologies around the world.
