A HISTORY OF SCIENCE AND TECHNOLOGY IN THE PHILIPPINES* by Olivia C. Caoili** Introduction The need to develop a country’s science and technology has generally been recognized as one of the imperatives of socioeconomic progress in the contemporary world. This has become a widespread concern of governments especially since the post world war II years.(1) Among Third World countries‚ an important dimension of this concern is the problem of dependence in

Biology (D) Ms. Wainman The relationship between Photosynthesis and cellular respiration Introduction: Photosynthesis is the process which used by plants to capture light energy and use it to do chemical reactions that change carbon dioxide and water into oxygen and energy (ATP)‚ carbohydrates just like sugar. Cellular respiration is the process that releases energy by breaking down glucose and other food with oxygen. Plants cells do photosynthesis and cellular respiration both ‚but animal cells

EXPERIMENT – 9 To Prove that Light is Necessary for Photosynthesis. Aim : To show experimentally that light is necessary for photosynthesis. Requirements : A potted plant‚ iodine solution‚ black paper strip‚ paper clips‚ water bath. EXPERIMENT PLEASE VIEW THE ANIMATION FILE FOR THE PROCEDURE Observation : 1) The region of the leaf which was exposed to sunlight turns blue in colour. 2) The region of the leaf covered with black strip turns brownish in colour

Dispersion Of White Light by a Glass Prism: When a beam of white light is passed through a glass prism‚ it is split up into a band of colours called spectrum. This is called dispersion of white light. The spectrum of white has the colours violet‚ indigo‚ blue‚ green‚ yellow‚ orange and red (VIBGYOR). The red light bends the least and the violet light bends the most. A rainbow is a natural spectrum appearing in the sky after a rain shower. It is caused by the dispersion of sunlight by water

Science in everyday life In its broadest meaning of ’knowledge’‚ science enters the life of even the most primitive human being‚ who knows the safe from the poisonous berry‚ who has stored up some rudimentary ideas about building a hut‚ sharpening a spear‚ and fishing in the river. this knowledge‚ or accumulation of experience‚ distinguishes man from the animal which has to rely on instinct. Yet‚ for most people ’science’ means a number of abstract subject such as physics‚ chemistry‚ biology

How to conduct a hoax: Memory Plus and the placebo effect Shawna Rosser‚ Shannon Ciuk‚ Martina Zhelezarova Massachusetts College of Liberal Arts Abstract This study’s objective is to test the placebo effect in an attempt to measure if participants will notice expected results from a product when primed. Although no active drug was be given‚ participants were told that the placebo capsules (gelatin capsules filled with cornstarch) were actually “study-boosting” capsules called “MemoryPlus‚”

The Light Bulb: One of the Most Useful Inventions in the World People need light to be able to see. In the morning‚ there is sunlight. But in the night‚ people use electric light made from light bulbs. Without light bulbs‚ people would not be able to see and would have to rely on their other senses to do tasks. Without light bulbs‚ our lives would be very different. The light bulb is a very useful invention that people all over the world use every day. The creation of the light bulb can be traced

Light is just one portion of the various electromagnetic waves flying through space. The electromagnetic spectrum covers an extremely broad range‚ from radio waves with wavelengths of a meter or more‚ down to x-rays with wavelengths of less than a billionth of a meter. Optical radiation lies between radio waves and x-rays on the spectrum‚ exhibiting a unique mix of ray‚ wave‚ and quantum properties. At x-ray and shorter wavelengths‚ electromagnetic radiation tends to be quite particle like

Cause and Effect Paper The effects of drugs on unborn and born babies are outrageous. “1 out of every 2 women pregnant right now is on drugs. Effects 145” The most commonly taken drug during pregnancy is caffeine. It’s most common because caffeine is in a lot of our every day substances such as; coffee‚ soda‚ tea and chocolate.
