OUTLINE - Assignment Example In the present age where there is growth hence need for more food, the pesticides should be used as much as critics may perceive them to be poisonous. The Environmental protection Agency provides that food may not harm individuals if they are washed (Robin, pp.30) I. To know if the food that individuals eat is safe, one should be aware of the amount of pesticides left on the food consumed. This amount of pesticide is referred to as pesticide residue. According to the Environmental Agency, there is an amount that when left on the food makes it safe. This amount that is permitted on the food is known as pesticide tolerance. For the determination on what is to be left, the Environmental protection Agency dictates environmental and health risks that pesticides pose (Robin, pp.30) a) For the persons who do not consume organic foods, there are measures that can be considered to make the food harmless. Firstly, if foods are washed the consumption of pesticides are reduced to some amounts. The most effective way of washing is by the use of running water rather than soaking or dunking as it washes away pesticide on the surface unlike the other two that scatter them on the surface b) Apart from the washing effectiveness can be achieved by scrubbing vegetables and fruits like root and melon vegetables like root and melons vegetables. The leafy vegetables outer layer should be cast off to lessen exposure. Peeling vegetables and fruits if need be may be of help. Skin and fat can be sheared from poultry, fish and meat to lessen the pesticide residue amount that is in fats. In addition, eating various vegetables and fruits limits exposure to one pesticide type. A dry cloth should be used in drying of food to avoid contamination from towel. The consumers ought to know that organic food contains pesticides. In fact 95% of additives in organic food are organic. I. There are ways to decrease the pesticide amount that are got on foods, although

Make a plane of the investigation and a report for the investigation Assignment

Make a plane of the investigation and a report for the investigation There should be two sections in this . In this in - Assignment Example Basically, the duration of burning of the candle is dependent on the amount of oxygen. The word equation for the burning candle wax that supports this explanation is as given (Oldham, 2005). (Hydrocarbons) + Oxygen ----> Carbon dioxide + Water (Hydrocarbons). This experiment entails burning candles. One, two and three, candles would simultaneously be held on a tray while confined in a jar. Time taken by each of the candles before going off would be recorded. This experiment is considered following a thorough review of many literatures that show that there is lacking experiments done to explore the differences in the rates of Oxygen consumption between one, two or more candles. As a result, it has not been clear whether if the sets are set running under constrained Oxygen, which of the three would go off first. This experiment, therefore, helps correlate the amount of oxygen consumed and the number of candles. This in effect, would help steer clear any double concerning the dependency of candles on oxygen gas during the burning process. Moreover, the experiment can help ascertain the components of a candle as a bi-product of hydrocarbons. This experimental set up is divided into two sections: The experimental plan and the report section. Title The Burning Candles Experiment. Aim The aim of this experiment is to investigate the differences in the rate of Oxygen consumption between one, two and three candles. ... Time taken by the one, two and three candles before going off served as the independent variable. Material you need to carry out the experiment Materials to be used in this experiment include a tray, a stop watch, one, two, and three same sized candles, jar and match box for lighting the candles. Methods Observation as a method is considered to be the most and, therefore, the applied method in this experiment for data collection. Raw data/observations No of Candles Time taken for the Lambs to go off in Seconds 1 60 2 35 3 15 Results It was found out that one candle took the relatively longest time to go off followed by two candles and finally, three candles, which took the shortest time before going off. Discussion From the graph shown below, there is a linear correlation between the number of candles and the time taken for the candles to go off. It is clear that increase in the number of candles causes a significant decrease in time the candles take to go off. Taking into considerat ion the fact that the number of candles is directly proportional to the rate of the amount of Oxygen consumed, it implies that increase in the number of candles results into an increase in of the amount of Oxygen consumed. On the other hand, the less the number of candles used, the less the rate of amount of oxygen consumed thus the higher the time taken for the candles to go off. This is because the burning up of candles is purely depended on the amount of Oxygen confined in the jar. Therefore, increasing the number of candles causes a proportional increase in the rate of consumption of Oxygen. This causes the candles to go off at shortest time possible. This is explained by the linear graph shown below. The
