is to see which color bulb attracts the most insects at night time. I will use the same lamp for both bulbs and put it in the same location outside a window so I can observe the lamp without disturbing the insects with my presence. I will watch one color for ten minutes and wait 20 minutes after to do the other color. This is to make sure the second light is not having similar bugs recorded from the first light. For every observation day I will switch the order of the bulbs to also see if time of

LIGHT IN PHOTOSYNTHESIS Theory: Leaf discs float normally. When the air spaces are infiltrated with the solution the overall density of the leaf disc increases and the disc sinks. The infiltration solution includes a small amount of sodium bicarbonate. The bicarbonate ions serve as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy – causing the discs to rise. Since cellular respiration is taking place

in the day time. Having observed these problems being encountered‚ this project will be developed to bring about the automation of the switching of lighting system using light depending resistor (LDR). The project is an electronic switch that is controlled (turned on and off) by the amount of light shining on the LDR. When light strikes the LDR‚ the switch opens (turns off); when the LDR is in darkness‚ the switch

Automatic Street Light [pic] Submitted By: Introduction Automatic Streetlight needs no manual operation for switching ON and OFF when there is need of light. It detects itself weather there is need for light or not.

neon lights: -consists of brightly glowing electrified glass tubes or bulbs that contain rarefied neon or other gases History: -Neon (the element) was discovered in 1898 by William Ramsay and Morris W. Travers. After they had discovered neon‚ they had explored neon’s many properties using an electrical gas discharge tubes. They later wrote that “the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget.” -following neon’s discovery‚ neon tubes

of Light on Snapdragon Flowers Introduction: It is a well-known fact that plants need light for nourishment‚ yet many people are ignorant of the reasons behind this. The biological process by which green plants utilize carbon dioxide‚ water and sunlight to form their own food is called photosynthesis (unknown). Past research has demonstrated that red and blue rays maximize this process (Rothenburger‚ 1993). The purpose of this experiment was to examine the effect of several different light sources
