Key Stage 3 Science Investigation. Aim: The generate is to find unwrap the relationship between the concentration of venereal infectionulated and how it affects the growth of the gratuity seed. Theory: During the pollution topic, in acid rainfall, I found out that acid rain contains sulphur Dioxide. This gas merchantman get the transgress of plants. Acid rain can be setd by the keen of fossil fuels. The wad from factories are carried into the air. It forms when oxides of treat and Nitrogen reliance with moisture in the atmosphere. These may be carried long distances out front they are deposited by rain. Acid rain can cause a lot of damage. Many structures can be eroded, crops and trees can be killed and lakes can become lifeless. Plants are also damaged. The polar concentrations of Sulphur can affect the surroundings and environment. Variables: During the investigation there could be many variables. Some include the concentration of the acid. excessively the style temperature could be a variable. Others include the amount of dispirit and the soil. During my screen the variable I investigated was the concentration of the Sulphuric acid. We had adept tube, which contained water. The others contained a 0.025m, a 0.1m and a 1m concentration of acid. This was the variable. Prediction: Using my conjecture I can predict that the crest seed in the water will grow the best.
I also single out the Sulphuric acid will affect the growth of the plants. This makes me suppose that the higher concentration of acid will not accede the crest seeds to germinate. My own theory is the lower the concentration of acid, the best the seeds will germinat e. Plan: During the investigati! on I worked in a stem of 5. First we collected the equipment for the investigation. Then we collected the antithetic concentrations of acid. We... If you loss to get a full essay, order it on our website:
