Center Science Fair “Plants Growth investigation” Student: Daniela Tristan. Teacher: Mrs. Pena. 2010. Title of the project: Plants Growth investigation Abstract: The purpose of this experiment is that by watering more a plant will help it grow more or less. I hypothesized that the plant that will grow the most will be the plant that will be watered the most. Hypothesis If a plant given an unlimited supply of moisture will grow more rapidly than a plant given the recommended

Organization of the United Nations (FAO) data‚ between 1961 and 2005 fertilizer applications in the Philippines increased by 1000%‚ while yields of rice and maize increased only by 200% and 280% respectively‚ and the yield of pulses remained about the same. From 1977 to 1987 pesticide use increased by 325%‚ while rice yield increased by only 30%. Pesticide imports have continued to increase‚ while rice and corn yields have increased at a much smaller rate. In general‚ the excessive and inappropriate

Preface Bangladesh is largely ethnically homogeneous. Indeed‚ its name derives from the Bengali ethno-linguistic group‚ which comprises 98% of the population. Bengalis‚ who also predominate in the West Bengal province of India‚ are one of the most populous ethnic groups in the world. Variations in Bengali culture and language do exist of course. There are many dialects of Bengali spoken throughout the region. The dialect spoken by those in Chittagong and Sylhet are particularly

Some of the most bizarre and fascinating plants in the natural world are undoubtedly carnivorous plants. Carnivory‚ defined as the consumption of animal tissue‚ is often only associated with the animal kingdom. However the existence of carnivory is widespread and diverse in the plant and fungi kingdoms as well. Specifically carnivorous plants‚ which originally descended from exclusively photosynthetic plants‚ have evolved elaborate‚ efficient‚ and diverse methods to capture‚ digest‚ and metabolize

planning to study biology in college‚ the process of natural selection explains so much about the modern day life on earth. There is perhaps no phenomenon more wondrous or perplexing than the development of complex life on our planet. Over the countless years of human existence‚ many have attempted to explain just how life came to be. I too have asked how complex life on earth arose‚ and for this answer‚ I turned to science. The process of natural selection is very important to my worldview because
