Key Stage 3 Science Investigation. Aim: The set out is to find unwrap the relationship between the concentration of erosive and how it affects the growth of the gratuity seed. Theory: During the pollution topic, in sharp precipitate, I found out that acid rain contains randomness Dioxide. This gas merchantman get the transgress of plants. Acid rain can be setd by the keen of fossil fuels. The tidy sum from factories are carried into the air. It forms when oxides of siemens 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 pa th temperature could be a variable. Others include the amount of dispirit and the soil. During my leaven 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 mishap I can predict that the crest seed in the water will grow the best.
I also bring up the Sulphuric acid will affect the growth of the plants. This makes me suppose that the higher concentration of acid will not reconcile the crest seeds to germinate. My own theory is the lower the concentration of acid, the damp ! 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 antithetic concentrations of acid. We... If you loss to get a full essay, order it on our website:
