Demonstrate the making of popcorn to pupils. Released by burning a small food item, like a nut or a piece of popcorn.
Learn Science Fair Projects Everyone knows popcorn is a great tasting snack, but it is also a fascinating food and great subject for your science fair or school project.
Take a look through these sections for helpful information. What makes popcorn pop? People have been fascinated by popcorn for centuries.
Native Americans believed that a spirit lived inside each kernel of popcorn. When heated, the spirit grew angry and would eventually burst out of its home and into the air as a disgruntled puff of steam. A less charming but more scientific explanation exists for why popcorn pops.
Popcorn is scientifically known as Zea mays everta. Popcorn is a whole grain and is made up of three components: Of the 4 most common types of corn—sweet, dent also known as fieldflint also known as Indian cornand popcorn —only popcorn pops! Popcorn differs from other types of corn in that its hull has just the right thickness to allow it to burst open.
Each kernel of popcorn contains a small drop of water stored inside a circle of soft starch. Popcorn needs between The soft starch is surrounded by the kernel's hard outer surface. As the kernel heats up, the water begins to expand.
Around degrees the water turns into steam and changes the starch inside each kernel into a superhot gelatinous goop. The kernel continues to heat to about degrees. The pressure inside the grain will reach pounds per square inch before finally bursting the hull open.
As it explodes, steam inside the kernel is released. The soft starch inside the popcorn becomes inflated and spills out, cooling immediately and forming into the odd shape we know and love. A kernel will swell times its original size! Where to begin an experiment?
There are a lot of experiments you can try using popcorn. First, you need to figure out what you want to compare and what you can measure. What is it that you want to compare?Popcorn Laboratory Problem: Popcorn kernels explode into delightful, edible parcels because of a build-up of pressure inside the kernel during heating.
In this experiment you will try to calculate the pressure inside a kernel of corn. 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.
NUCLEAR POPCORN 1 Grade: 7 – 12 Intended Learning Outcome: – Reason mathematically Science in physics education and was recognized as Intern Teacher of the Year in While working in Florida, he consulted on the design of an experiment This lab will simulate radioactive decay.
By eliminating random kernels, the. The most intriguing part of popcorn is the science behind how it pops. Popcorn is the only grain in the corn family that pops open when exposed to temperatures above ° C.
A popcorn kernel is composed of 3 parts: the pericarp, germ, and endosperm. This popcorn science project investigates how popcorn works. Ever wonder how those hard little kernels of corn pop into the soft puffs?
Before starting, if you are not sure how to properly conduct an experiment, you can find out how by following our experiment guide. First: remember to get permission first if you are not allowed to use the stove without supervision.
