series of experiments were done to gain a greater understanding of photosynthesis, plant pigments and light absorption and transmittance by/through plant chlorophyll and accessory pigments. Photosynthesis is the process by which plants use energy from light (i.e. the sun, photons, electromagenetic energy), water, and carbon dioxide to produce ‘food’ for themselves, or some for of sugar, like glucose. Photosynthesis has two stages which take place within the chloroplasts of a plant cell, where the

CHAPTER I INTRODUCTION A. Background of the Study Philippines is an agricultural country. The geographical location of this country in the Tropic plays the major role to this fact. Aside from rice, Filipinos produce most of the crops that they use to make food that they serve in their dining tables. In the countryside, houses have different kinds of vegetables, fruits and root crops planted on their backyards. Unfortunately, people living in urban places don’t have backyards. There

pigment in plants and they absorb red and blue light the best. They reflect green light, which is why plants typically look green to us. I decided to test this with China Rose radishes. My question that I am testing is what color of cellophane wrapped over the radishes, violet, red, or green, will make them grow the tallest? Based on this prior knowledge of colors of light and their effects on plant growth, I predict that the radishes planted under the violet and red cellophane will grow taller than

ingenuity cannot hope to match it. Right from the sky above to the sea below, nature abounds in the richness of colour. The human eye and the human mind respond to this world of colour and identify themselves with it. When a person is cheerful and bright we refer to him as a 'colourful personality', similarly the different colours are used to indicate human moods and attitudes: blue is associated with depression, white is likened with serenity, green with jealousy and red with rage. Colour is also used to

pattern – When an electric field is applied, the crystals align to the field – The crystals themselves do not emit light, but ‘gate’ the amount of light that can pass through them • Crystals aligned perpendicular to a light source will prevent light from passing through them Each LCD segment is aligned with an electric field A light source (backlight) is needed to drive light through the aligned crystal field Courtesy of Sharp Passive displays Passive LCD panels – Consists of a grid of row

Leaves Turn Red BACKGROUND INFORMATION Daylight time and temperature decrease during autumn as a warning for trees –and many other organisms- that winter is coming. Many trees lose their leaves; but before that is done the green color of the leaves turns into yellow, red, and orange. These changes do not happen randomly; behind it there is a transformation of the pigments in leaves. One of the main pigments in leaves is chlorophyll and it absorbs the red and blue light from sunlight that

investigation you will explore some of these factors. Materials In order to test the intensity of light, there are several different materials needed. Those materials are as follows; colorimeter probe (spectrophotometer), red food color solution, blue food color solution, green food color solution, deionized water, test tubes and rack, pipet, and a timer. Procedures: Part 1 The first part in the experiment is to pour each colored solution into a vial, then calibrate the spectrophotometer. The calibration

break the gears holding the archimedean screw together. You may now backtrack to that new type of door you saw earlier, and break it down. Inside grab the GREEN CHEST and a RED CHEST before continuing along the path. When you slide down the next ramp you'll land onto a platform where you have to face two Minotaurs and some firebirds. Grab the BLUE/GREEN CHEST and then pull the lever here. Jump onto the lava rock and you will float along the lava flow. You will fight a small wave of fire crab-spiders before

Abstract: The purpose of my project is to find out two things about students at my school: 1. Is hair related to eye color? 2. Is favorite color related to favorite ice cream flavor? I took a survey of students, and used the chi square (χ2) statistic to see if the data is related. The χ2 statistic showed that hair color and eye color are related, but favorite color and favorite ice cream flavor are not related. Purpose: To use statistics to find out two things

beautiful and shine. My color scheme: Green is an emotionally positive color, giving us the ability to love and nurture ourselves and others unconditionally. A natural peacemaker, it must avoid the tendency to become a martyr. Being a combination of yellow and blue, green encompasses the mental clarity and optimism of yellow with the emotional calm and insight of blue, inspiring hope and a generosity of spirit not available from other colors. Green promotes a love of nature, and a love of
