CSTS Lesson 5 - In the Philippines, Lecture notes of Science education

Angelo State University (ASU)Science education

Despite being considered a developing country, the Philippines also contributes to the global advancement of science and technology. It is quite remarkable to note the ingenuity of the Filipinos despite the lack in resources. The Philippines is known to be one of the most vulnerable countries in terms of natural disasters. Many of the discoveries and inventions made by the Filipinos were therefore built from indigenous materials or created to adapt to the harsh tropical environment.

ALCALA DELMUNDO EJEEPNEY INCUBATOR LARVICIDAL

QUISUMBING SALAMANDER SALTLAMP

EXPLORE

LET’S BECOME AN INVENTOR!

Filipinos are well-known of its many scientific and technological developments. Some of these inventions are globally accepted and used for the benefit of comfortability and satisfaction. You may not know that the things around you are products of “pinoy” brilliant minds. As an activity, think of anything that is not still invented/materialized by inventors and scientists. Create your improvised machine/inventions/technology by making a blueprint of it. Draw your invention on the space provided. Name your invention and discuss how it woks. Name of Invention: How your device/machine works:

  • It may be utilized to travel island to island. Since Philippines is an archipelago, the Salamander is a useful invention that has a lot of potential. SALT LAMP by AISA MIJENO
  • One of the major needs in the Philippines, was a developing nation, is electrification. Electricity powers various types of machines, including the light sources. In many rural areas in the country, activities would cease when it gets dark.
  • Filipinos have resorted to using candles and kerosene lamps but they carry certain risks as they are fire hazards.
  • Solar power is also a welcome development but like rechargeable batteries, solar panels are too expensive for ordinary Filipinos.
  • Aisa Mijeno was able to invent a lighting system that utilizes a material abundant in the Philippines—saltwater
  • Sustainable Alternative Lighting (SALt) Lamp , an environment friendly light source that runs on salt water.
  • The SALt Lamp is safer as it poses no risk of fire and emits no toxic gases. Aside from people who live in coastal areas, it may also benefit those from far-flung barrios because they can make their own saltwater by mixing two tablespoons of salt and a glass of tap water. MEDICAL INCUBATOR by FE DEL MUNDO
  • A common problem in the Philippines is the high mortality rate of newborn babies. One reason for this problem in the 20th^ century was the lack of available incubators especially in far-flung rural areas due to lack of resources and electricity.
  • DR, Fe Del Mundo, a Filipina pediatrician and the first Asian woman admitted into Harvard Medical School, devised a 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. Hot water bottles were inserted between the baskets to provide warmth and a makeshift hood to allow oxygen circulation.
  • Its main purpose was to maintain conditions suitable for a newborn, usually a pre-termed baby.
  • Other breakthroughs in the Philippine Medicine attributed to del Mundo include her works on the immunization and treatment of jaundice and the BRAT diet for curing diarrhea.

Dr. Fe Del Mundo with her invention, Medical Incubator (The picture is an improvised version) MOSQUITO OVICIDAL/LARVACIDAL TRAP SYSTEM by DOST Dengue, a mosquito-borne viral illness, is endemic in tropical and subtropical areas, including the Philippines. This virus is usually transmitted by Aedes Aegypti mosquito, rampant during the rainy seasons. Insecticides were previously were used to kill the species. However, recent studies show that insecticide resistance has evolved in some mosquito population. Likewise, insecticides are harmful to humans and to the environment. In 2010, the Department of Science and Technology and the Technology-Industrial Technology Development Institute (DOST- ITDI) was able to introduce the Mosquito Ovicidal/Larvicidal Trap System. Also known as OL Trap. This Trap system is made of natural ingredients that are lethal to Mosquitos but safe for human and the environment. EJEEPNEY A major innovation that changed the transportation industry in the Philippines was the development of the jeepney. This iconic public utility vehicle was built using the military jeep lefts by Americans
