How do freezers produce ice? How do food items get cold inside refrigerators? And how do air-conditioning units release cool air? All these appliances use the same process to function - refrigeration. But to know what refrigeration is, we need to understand the science of thermodynamics in the simplest way possible.

In the Philippines, teachers focus more on the definition of electricity and the people who discovered it than on how it is produced in the first place. We know that Benjamin Fraklin, the greatest American statesman and inventor, was the one who discovered the nature of electricity through his experiments with lightning in 1740s. Thomas Edison applied electricity to light a bulb in 1879 while Nikola Tesla developed a system of generating and transmitting alternating current (AC) electricity in the 19th Century. James Watt, on the other hand, invented the steam engine, which remains the basic structure of most engines and power generators to this day.

Alexander Graham Bell was credited for having invented the telephone on March 10, 1876. It was a magnificent invention, that helped us in so many ways. It is only proper that we give proper recognition to this device by trying to understand how it functions. But we would not go to the extent of explaining acoustics or the science of sound to make our point.

Rather than asking students who invented the airplane, it is important that Filipino educators begin explaining to their students what makes an airplane fly? We all know that Orville and Wilbur Wright developed a flying machine that first lifted from the grounds of Kitty Hawk, North Carolina and stayed on the air for 12 seconds on December 17, 1903. But it is time for both teachers and students to know how and why that machine flew in the first place.
