  tea
• vIt was believed that the first tea was drunk by a Chinese emperor.
• vOnce considered the only man-made structure that could be see from outer space, the Great Wall of China said to be the largest and most extensive infrastructure that the nation built.
• vIt was developed by Chinese alchemists who aimed to achieve immortality.

  gunpowder
• vGunpowder is widely used to propel bullets from guns and cannons which cause countless deaths.
• vGunpowder is also used in fireworks during important celebration in China.
• Wars were prevalent during this time

  Medieval/Middle Ages
• vTrade and commerce among nations increased, which resulted in greater demands for transportation technology. Some of the most innovative minds came from this period.

  Medieval/Middle Ages
• vGreat technology was needed in the fields of weaponry, navigation, mass food and farm production, and health

  Medieval/Middle Ages
• vJohann Gutenberg was able to invent the printing press, a more reliable way of printing using a cast type.
• vThe printing press was invented to address the need for publishing books that would spread information to many people at a faster rate.

  printing press
• vZacharias Janssen was able to develop the first compound microscope.
• This microscope was key in discovering news means in preventing and curing various illnesses.

  Microscope
• vThe invention of the telescope, an optical instrument that helps in the observation of remote objects, was a great help for navigators during this time.
• vFor open area battles, people developed cross bows and long bows so that they could attack the enemies at long ranges, keeping themselves safe with he protection of walls and fortresses.

  war weapons
• vIn close-range hand to hand combat, soldiers should wear something to protect themselves, a need addressed by the creation of iron body armors. However, body armors were heavy and limited their movements. The problem was eventually solved by the invention of the chainmail.

  war weapons
• vThe booming world population during the nineteenth century onwards demanded that more goods be produced at a faster rate.

  vPeople needed efficient means of transportation to trade more goods and cover a larger distance.

  v faster and easier means to communicate and compute should be developed to establish connections between and among nations

  vHowever, due to massive industrialization, the modern times again faced more complicated problems. Food processing and medicine posed some of the bigger challenges since health was of great concern.

  modern times
• vLouis Pasteur invented pasteurization, the process of heating dairy products to kill the harmful bacteria that allow them to spoil faster. Through this process, milk could be stored and consumed for a longer period. It also prevented illnesses caused by harmful bacteria.
• vKerosene was later on referred to as the “illuminating oil” because it was used at first to provide lighting to homes.
• vSameul M. Kier was able to invent kerosene by refining petroleum.
• vThe development of the telephone by Alexander Graham Bell was one of the most important inventions at that time.
• vThe creation of modern calculators did not only pave the way for easier arithmetic calculations, but also resulted in the development of more complex processing machines like the computer.
• vVictor Llave and his team at H2O technologies were able to invent the Salamander, an amphibious tricycle that can cross not only flooded streets but also rivers and lakes
• vA young Filipina inventor named Aisa Mijeno was able to invent a lighting system that utilizes a material abundant in the Philippines – saltwater.
• Dr. Fe del Mundo,a Filipino pediatrician and the first Asian woman admitted into Harvard Medical School, devised  medical incubator made from indigenous and cheap materials which did not run on electricity.
• Dr. del Mundo’s incubator was made by placing a native laundry basket inside a bigger one.

  Its main purpose was to maintain conditions suitable for a newborn, usually a pre-term baby.
• vThis virus is usually transmitted by Aedes aegypti mosquito, rampant during the rainy season. Insecticides were previously used to kill the species.
• vIn 2010, the Department of Science and Technology-Industrial Technology Development Institute DOST-ITDI) was able to introduce the Mosquito Ovicidal/Larvicidl Trap System, also known as OL Trap. 
• vThis modern type of transportation utilizes electricity instead of the more expensive diesel. It is environmental-friendly since it does not emit any smoke and noise.

  ejeepney
• vIn response to the ASEAN 2015 Agenda, the government, particularly the Department of Science and Technology (DOST), has sought the expertise of the National Research Council of the Philippines (NCRP) to consult various sectors in the society to study how the Philippines can prepare itself in meeting the ASEAN 2015 Goals.
