moves up and down in a cylinder. Generally‚ the automotive engine uses four strokes to convert chemical energy to mechanical energy through combustion of gasoline or similar hydrocarbon fuel. The heat produced is converted into mechanical work by pushing the piston down in the cylinder. A connecting rod attached to the piston transfers this energy to a rotating crankshaft Engines having from 1 to 16 cylinders in in-line‚ flat‚ horizontally opposed‚ or V-type cylinder arrangements have appeared

creating a chemical reaction on fuel with air (compression and ignition)‚ and converting the energy into rotation (expansion). The intermittent energy source combined with the nature of this mechanism make the engine naturally vibrationprone. Multi-cylinder configuration and many of the engine design elements are reflections of the effort to reduce vibrations through the act of balancing.

left for 5 minutes. Control Variables: Variable How it is measured Why it needs to be measured Mass of beetroot cylinder A weighing scale should be used to ensure all beetroot cylinders weigh 1 gram. If the mass of the beetroot cylinder varies it may cause a difference in diffusion capabilities. Length of beetroot cylinder The in order to ensure the surface area is kept the same‚ each cylinder must be 2 cm long. This should be measured using a 15cm ruler. If the lengths are different it would result

Testing the effect of concentration on rate of reaction Plan: We are investigating the effect of nitric acid on calcium carbonate. We are doing this experiment‚ as we would like to understand the effect that acid rain has on limestone. We also want to understand how acid can have an effect on rate of reaction. The word equation for the reaction that will take place is: Calcium Carbonate + Nitric Acid Calcium Nitrate + Carbon Dioxide + Water The balanced symbol equation

“To stimulate life‚ – leaving it then free to develop‚ to unfold‚ - herein lies the first task of the educator. In such a delicate task‚ a great art must suggest the moment‚ and limit the intervention in order that we shall arouse no perturbation‚ cause no deviation‚ but rather that we shall help the soul which is coming into the fullness of life‚ and which shall live from its own forces. This art must accompany the scientific method.” Dr.Maria Montessori‚ The Montessori Method Comment on the
