An Investigation Into How the Thickness of Insulation Affects the Time a Drink Takes to Cool Down · Aim In this investigation I am trying to find out how the thickness of insulation around a drink in a cup affects the time a drink takes to cool down. I want to find out if insulation does affect the cooling time of a drink and if so how. I would like to produce an unbiased and fair set of results. I would like to produce results that match my prediction and the scientific theory behind them. I would like there to be an obvious trend in the results and a pattern which can be easily be used to predict further results when changing the thickness of the insulation. Preferably there would be no anomalous figures. I aim to undertake a safe and well-planned investigation after which I will be able to arrive at a thorough and decisive conclusion. I aim to do the right amount of experiments for there to be an accurate result, not to do too many unnecessary ones. I will conduct some preliminary experiments to decide on what measurements I will take and also what range of thickness to use. My overall aim is to perform a safe, well planned, precise and conclusive investigation into how the quantity of insulation affects the time it takes for a drink to cool down. · Prediction My prediction is that the more the thickness of the insulation is increased the longer the drink will take to cool down. I also predict that for every two layers added the temperature change will go down by about 2oC. I do not predict that all of my results will follow a line of best fit exactly as that would be very hard to achieve but they will probably have a trend. There is a possibility of getting one or two anomalous results but I hope that my results will follow a pattern. Here is a graph of how I expect my results to look:
