Does Temperature of Kernels Affect Popcorn Yield? Project Design Plan This experiment will attempt to determine if the temperature that popcorn kernels are stored at will affect the amount of un-popped kernels when using a hot air popcorn popper. Popcorn kernels contain moisture inside of them which‚ when heated‚ turns to steam and expands that in turn causes the kernel to explode. Popcorn.org states that loss of moisture content can cause less yield amounts when popping popcorn (popcorn.org‚ 2014)

Salt is soluble and sand will sink to the bottom‚ you can separate the rest with filtering and distillation (boiling). If salt and sand are a mixture‚ then we can separate them by physical processes.

1. Prepare the salt‚ sugar‚ sand‚ and measuring teaspoon. 2. Once the ice cubes are set up in their bowls‚ quickly add the substances to the ice cubes so that they don’t melt before adding the substances. 3. Place three ice cubes quickly into each of the four bowls. 4. Arrange the ice cubes so that only the corners are touching‚ forming a triangular shape. 5. Carefully sprinkle ½ teaspoon (tsp.) of salt over the ice cubes in one bowl. 6. Sprinkle ½ tsp. of sugar over the ice cubes in another bowl

History[edit] Popcorn on the cob before shelling Popcorn was first discovered thousands of years ago by the people living in what is now Peru. It is one of the oldest forms of corn: evidence of popcorn from 3600 B.C. was found in New Mexico and even earlier evidence dating to perhaps as early as 4700 B.C. was found in Peru. Some popcorn has been found in early 1900s to be a purple color.[1][2] The legend that the English who came to America in the 16th and 17th centuries learned about popcorn from the

Microwave Popcorn: What Storage Method Pops The Most Kernels? Mark B. Houser Western Governors University Integrated Science December 20‚ 2012 Microwave Popcorn: What Storage Method Pops The Most Kernels? Most packaged perishable food products come with an expiration date. In order to extend the life of the product we might freeze‚ refrigerate‚ or can it if possible. Popcorn is one of those items that my family has used the freezing process to extend its utility. One thing that I did not consider

Do different brands of popcorn affect how many kernels pop? Introduction The grocery store shelves are filled with many varieties‚ sizes‚ and brands of the same item. There are numerous kinds of popcorn‚ large and small‚ produced by different manufacturers. Some people choose products based on need‚ some base their decisions on price and some base their decision on quality or brand loyalty. With all of these options it can be difficult to choose. You may want to save money but at what cost? In

Running head: KERNEL DISTRIBUTIONS Kernel Distributions of Linux Diego Avendano AUI Online KERNEL DISTRIBUTIONS Kernel Distributions of Linux Every operating system needs a way to communicate with the user‚ the hardware and software. To accomplish these tasks‚ every operating system uses kernel and shell. Both kernel and shell work together forming a communication bridge between the user and the operating system. Linux allows the user to create its own kernel‚ making it easier to run the

quantity of water in several different types of popcorn. Determining the amount of water in the product will determine the likelihood of it popping. More water in a piece of popcorn increases the amount of pressure buildup when it is heated. With the data it will be determined if more expensive popcorn equates to a better‚ more reliable popcorn. Part 2: The purpose of this experiment was to create a method of separating a mixture of popcorn‚ sand‚ salt‚ and iron filings. When separated the individual

Popcorn Lab Report Background: Chemistry is the study of matter‚ its properties and the ability to change. This can be used to describe the process of popcorn and the change it undergoes to turn into the movie theater snack we know. The United States supplies most of the worldwide supply of popcorn available today‚ although the popcorn has to meet specific industry standards which can be tedious to do for the 50 million pounds of output per so sampling has to be used. Sampling is known as
