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

INTRODUCTION Radiation‚ flow of atomic and subatomic particles and of waves‚ such as those that characterize heat rays‚ light rays‚ and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy

The Effect of Gasoline Fumes on plants Introduction: This science fair project was conducted to study the effect of gasoline fumes on plants. The testing was done by placing plants beside a gasoline-filled container for different periods of time and temperatures. Hypothesis: Gasoline fumes cause plants to die - the longer the exposure to the fumes‚ the quicker the plants will die. Our second hypothesis is that exposure to fumes‚ at higher environmental temperatures‚ will result in quicker

Radiation Therapy What is radiation therapy? According to wikipedia Radiation therapy discovered in 1889 also known as radiotherapy‚ radiation oncology‚ or XRT‚ is the medical use of ionizing radiation as a part of cancer treatment to control malignant cells. Radiotherapy may be used for curative or adjuvant cancer treatment‚ with curative being the cure and adjuvant being additional treatment. Radiation therapy can also be used as palliative treatment‚ which is where a cure is not possible and

The effect of mobile phone radiation on human health is the subject of recent interest and study‚ as a result of the enormous increase in mobile phone usage throughout the world. As of November 2011‚ there were more than 6 billion subscriptions worldwide.[1] Mobile phones use electromagnetic radiation in the microwave range. Other digital wireless systems‚ such as data communication networks‚ produce similar radiation. In 2011‚ International Agency for Research on Cancer (IARC) classified mobile

The Affect of Different Colored Light on Plant Growth Puprose: Just as we are happier and healthier when we receive adequate sunlight‚ so are the plants and vegetation that we grow. Sunlight‚ or other means of artificial lighting is essential to help a plant grow into maturity. It is also necessary in aiding the plant to get the nutrients it requires to mature into a strong healthy plant. The process of the sun or other light helping to feed the plant is called photosynthesis. The light acts

the Amount of Water Effects Plant Growth By Dennis Marchuk Turner Ashby High School Grade 10 March 23‚ 2013 The purpose of this project was to determine how much the amount of water effected plant growth. This had been accomplished by taking three groups of plants and placing them next to one another. Each group contains two plants. Each one would be watered with a different amount of water. They would then be measured how much they grew. The growth of the three plants was compared. Hypothesis:

Radiation Exposure Do you know much radiation you are exposed to everyday? Many people are not aware of the radiation levels around them on a daily basis. I believe that exposure to radiation should be minimal. I think protection and prevention is vital. Being aware of the health risks and what can be done to protect yourself should be a well known piece of knowledge. If followed‚ this knowledge can help reduce radiation exposure levels. Exposure to radiation is higher today than it has ever
