erudition Report (Nature of Science)AimTo find pop step up the effect of the thickness of a cookie on the ability of the cooky to support a finite standard of freights ApparatusoWeightsoBiscuitsoThreadBackground Information Biscuits are designed to be strong so that they do not crumble easily. (http//www.nzmaths.co.nz/Number/CrossStrand/ biscuits.htm) A biscuit consists of flour, oil and other ingredients, which are packed together into a brittle solid. Therefore, biscuits can stand up to a finite pith of pitch before it flunks. HypothesisThe thicker a biscuit, the more weights it can support.Variables commutativeoIncrement of ThicknessoMethod of applying weightso shell of Biscuit oHow the Biscuit/Biscuits are placed Method of mesh ( freelancer Variables)oIncrement of Thickness Regular increment of 1 biscuit thickness oMethod of applying the weights Placing the weights gently onto the biscuits, increasing the weight by 100g each time, until the crackers devote. o the atrical role of Biscuit Use resembling Khong Guan Cheese CrackersoHow the Biscuit/Biscuits are placed The biscuits testament be strung tightly together and hung on a hook. (Refer to plot 1.1) DependentoThe number of weights that can be hung on the biscuits mapping 1)Drill a hole in the middle of the biscuit with a needle.2)Hang the weight holder on the biscuit.3)Place 100g weights one by one, until the biscuit breaks (Refer to draw 1.1)4)Repeat the examine with 2,3,4 and 5 biscuits5)Repeat the essay 3 times6)Calculate the average weight required to break the biscuits of different thickness7)Plot a graph to identify the principal(prenominal) trend of this experiment.8)Formulate a conclusion from the results. Margin of ErrorAs the weights obtained are 100g weights, they are not precise. Therefore, if a biscuit breaks when a 200g weight is hung on it, it does not mean that the biscuit breaks at 200g. It is just an skinny amount. To utilize a spring balance would have caused the results to be more accurate. Secondly, whenever a new weight is added to the weight holder, the position of the set-up shifts a little.Natue of Science essays research papers Science Report (Nature of Science)AimTo find out the effect of the thickness of a biscuit on the ability of the biscuit to support a finite amount of weights ApparatusoWeightsoBiscuitsoThreadBackground Information Biscuits are designed to be strong so that they do not crumble easily.
