The purpose of the science project was to find out, “How does changing the insulation material affect the temperature of the hot water in the glass?” The hypothesis is, “If changing the insulation material affects hot water in the glasses, then the cotton balls will make the heat of the water stay longer than the other insulation materials.” The independent variable was the temperature and it was measured with a thermometer in Celsius. The newspaper had the highest average for the first and third trial. The foam had the highest average for the second trial. Averaging the average results, the foam had the highest mean. The results show that the hypothesis should be rejected because the foam had the highest temperature mean. An inference is that
