What is the Effect of the Colour of Light on the Rate of Photosynthesis? By Amelia Rowan‚ 12SDa Aim To discover whether the colour of the light source has any effect on the rate of photosynthesis of a sample of algae. Hypothesis It was predicted that the colour of the light source would have a very slight effect on the rate of photosynthesis. It was further predicted that when the sample was placed under the green light‚ the rate of photosynthesis would be the lowest. This hypothesis was arrived

ummary: Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Is there any person who comes to ON/OFF these lights? The following circuit that described below which perform this job automatically. This circuit employed the output from an uncomplicated light/dark activated circuit and oblige a relay in its output which can be further attached to switch ON/OFF a street light and electrical application in a household also. Many of the

I have chosen to write my paper on a fire that occurred on February 4th‚ 2007 and was initially reported at 0934 in a small town in Pennsylvania. The weather at the time of the incident included a high temperature of fourteen degrees‚ with a low of three degrees. Winds were between ten and twenty miles per hour and there were gusts up to thirty miles per hour. This fire killed one firefighter a 27 year old male with approximately thirteen total years experience twelve and a half of those being

Photosynthesis is the process by which light energy is used to convert inorganic compounds into organic substances with the subsequent release. There are many factors which can have an effect on the process of photosynthesis; in this laboratory experiment‚ the focus lies on carbon dioxide (CO2) availably and its effect on photosynthesis. By understanding the component that affect the rate of photosynthesis‚ one can do work to try and increase the rate of photosynthesis. The purpose of this laboratory

If you are interested in learning the benefits of high intensity interval training‚ your concern with personal fitness is likely greater than the average person’s. High intensity interval training at its most effective level is not for the average Jane or Joe. HIIT‚ as it is also referred to‚ can make even a professional athlete weep. But the results are worth it. High intensity interval training has the advantage of requiring much less time to produce great results. It is designed to achieve rapid

Photosynthesis vs. Semiconductor based solar cell. Photosynthesis vs. Semiconductor based solar cell. Wais Ghowsi Instructor: Meri Stanec SCI 115 April 24th‚ 2011 What is Photosynthesis? Photosynthesis simply means the conversion of light energy into chemical energy by living organisms. In photosynthesis‚ the raw materials are water and carbon dioxide. Energy is taken from sunlight and the end products give out glucose and oxygen. It is the most important‚ naturally occurring process

Scattering of Light | The scattering of light is an important observation in our daily life. The way light scatters off molecules in the atmosphere explains why the sky is blue and why the sun looks red at sunrise and sunset. This is because of the scattering of light. | | | Tyndall Effect A beam of light or laser‚ invisible in clear air or pure water‚ will trace a visible path through colloidal particles. This is known as the Tyndall effect after its discoverer‚ the 19th-century British
