Science Report (Nature of Science)AimTo find aside the effect of the onerousness of a cooky on the ability of the cookie to support a finite amount of weights ApparatusoWeightsoBiscuitsoThreadsetting Information Biscuits ar 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 color and other ingredients, which be packed together into a brittle solid. Therefore, biscuits can stand up to a finite amount of weight before it breaks. guessThe thicker a biscuit, the much weights it can support.VariablesIndependentoIncrement of Thicknesso order of applying weightsoType of Biscuit oHow the Biscuit/Biscuits are put Method of Control (Independent Variables)oIncrement of Thickness Regular increment of 1 biscuit onerousness oMethod of applying the weights Placing the weights gently onto the biscuits, change magnitude the weight by 100g each time, until the crackers break. oType of Biscui t Use identical Khong Guan Cheese CrackersoHow the Biscuit/Biscuits are placed The biscuits will be strung tightly together and hung on a hook.

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 approximate amount. To utilize a spring eternal sleep 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.
