Students demonstrate the scientific method as they explore what makes popcorn pop.
In this episode, host Dianna Cowern races against the clock to complete 20 physics experiments in five minutes. Feel free to try them at home but note that some require adult supervision. Part of the "Physics Girl" series.
Experiments illustrate the presence and properties of: 1) saccharides (glucose and starch) in fruits and vegetables; 2) lipids (fats) in nuts and vegetable oils; and 3) proteins in eggs, meat, and milk. Emphasizes that chemistry is all around us.
Corn is king. It can be found in other foods, in the ink for pens, and in gas for cars. Indeed, it's one of the most versatile substances on the planet. Today, it is a very different product than the one that once grew wild across North America. In this episode, Dr. Joe Schwarcz traces the evolution of corn. Part of the "Science to Go With Dr. Joe Schwarcz" series.
Enzymes are proteins which are manufactured by the human body during the process of protein synthesis. They are catalysts that drive every chemical reaction taking place in the human body, and they enable the human body to be built from proteins, carbohydrates, and fats. Enzymes are highly specific in their activity and form an enzyme-substrate complex speeding up processes as they lower the activation energy during a given reaction period. Through genetic engineering and by isolating specific enzymes, it has become possible to harness the power of enzymes.
