BIOLOGY COURSEWORK GARY MCGORRIGHAN 10/A Aim The aim of this experiment is to see whether the relationship between the amount of light affects the amount of oxygen produced. Hypothesis I predict that the further away the light source is the less oxygen produced. This is mainly due to there being light further away from the beaker, this resulting in a lower rate of reaction. Secondly when the light is about average, this will allow there to be an increase in the rate of reaction. And thirdly the light being too close, this allowing the rate of reaction to stay constant. This is all due to there being chemical energy, therefore the more energy provided the more food the plant makes. Equipment 1000ml beaker Water Inverted funnel Inverted test tube Metre stick Stopwatch Container of sodium hydrogen carbonate Spatula Thermometer Lamp Glass block Blinds Variables Chart Independent Dependent Controlled Temperature Water Same Weed Same thermometer Same Stopwatch Same Ruler Plan I plan to do the experiment in an accurate and carefully controlled manner, taking into account all relevant safety issues. Firstly I...
