Science Report (Nature of Science) siteTo find out the effect of the thickness of a cookie on the ability of the cooky to support a finite amount of burthens instrumentoWeightso biscuitsoThreadBackground Information cookys argon designed to be strong so that they do not founder easily. (http//www.nzmaths.co.nz/Number/CrossStrand/biscuits.htm) A biscuit consists of flour, oil and other ingredients, which ar jam-jam-packed together into a brittle solid. Therefore, biscuits can stand up to a finite amount of cant before it breaks. HypothesisThe thicker a biscuit, the more than than weights it can support.VariablesIndependentoIncrement of Thicknesso rule of applying weightsoType of Biscuit oHow the Biscuit/Biscuits atomic number 18 fixed mode of Control (Independent Variables)oIncrement of Thickness Regular maturation of 1 biscuit thickness oMethod of applying the weights Placing the weights gently onto the biscuits, change magnitude the weight by 100g each time, until t he crackers break. oType of Biscuit Use identical Khong Guan Cheese CrackersoHow the Biscuit/Biscuits ar move The biscuits will be strung tightly together and hung on a hook.

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 balance would own caused the results to be more accurate. Secondly, whenever a new weight is added to the weight holder, the cast of the set-up shifts a little.Natue of Science essays research papers Science Report (Nature of Science) buzz offTo find out the effect of the thickness of a biscuit on the ability of the biscuit to support a finite amount of weights machineoWeightsoBiscuitsoThreadBackground Information Biscuits are designed to be strong so that they do not get it easily.
