Objectives/Goals The purpose of my science project was to see if the density of different metals has a correlation with their thermal conductivity. Methods/Materials To test my experiment, I constructed 18-1 cm^3 cubes of various metals (aluminum, brass, copper, steel, and zinc) into blocks measuring 3x3x2 cm^3. I weighed each block to determine the density of each metal. After the density of each metal was determined, I marked the surface of each block black to equalize possible radiation due to their naturally occurring color differences. I then placed an ice cube onto each block and timed how long it took the ice cube to melt completely. I performed this test eight times for each metal at this volume, also with blocks measuring 4x4x1 cm^3 and 5x4x1 cm^3. A control variable for each test was used by constructing blocks of wood with the same dimensions. Results The results of my experiment determined that the density for each metal remained consistent
