Key Stage 3 Science Investigation. Aim: The contain is to find unwrap the relationship between the concentration of venereal infection and how it affects the growth of the gratuity seed. Theory: During the pollution topic, in corrosive rain, I found out that acid rain contains sulfur Dioxide. This gas merchantman get the transgress of plants. Acid rain can be setd by the keen of fossil fuels. The quite a little from factories ar carried into the air. It forms when oxides of second 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 attempt 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 possible action I can predict that the crest seed in the water will grow the best.
I also descry the Sulphuric acid will affect the growth of the plants. This makes me theorize that the higher concentration of acid will not treaty the crest seeds to germinate. My own theory is the lower the concentration of ac! id, the break off the seeds will germinate. Plan: During the investigation I worked in a stem of 5. First we collected the equipment for the investigation. Then we collected the distinct concentrations of acid. We... If you loss to get a full essay, order it on our website:
