GRAPHSupports HypothesisCaption: The graph is showing the temperature change of different materials over 20 minutes for trial 2.Summary: Copper has the highest temperature change (9.5C) and plastic has the lowest change in temperature (0C).

GRAPHMeanCaption: The graph is showing the mean temperature change of different types of conductors over 20 minutes for all trials.Summary: Copper has the highest temperature change (8.90C)and plastic has the lowest change in temperature (0.13C).

GRAPHStandard DeviationCaption: The graph shows the standard deviation of the collected data.Summary: Copper has the highest Standard Deviation with 0.54C and both plastic and glass has 0.09C of standard deviation.

In conclusion, copper would be a better conductor comparing with aluminum, plastic and glass.Based on the results of this experiment it can be concluded that the smaller specific heat capacity, the faster the substance can transfer thermal energy.Based on my research, this happened because copper has a smaller rate of specific heat capacity than other three materials.The independent variable was conductivity of different materials and the dependent variable was waters temperature.
