Introduction: This report required the successful identification of two unknown substances through experimental testing on a selective collection of materials and equipment. For the first substance (which will be either tin or aluminium)‚ two tests shall be done to ensure a decisive and educated decision onto what the substance is. The first step utilizes the dramatic difference in density between the two substances by measuring the volume and mass of the unknown substance. By calculating the volume

produced bronze by heating copper and tin with charcoal. * Iron Age (1000 BCE – 1 CE) – iron steel and lead was used for tools‚ weapons and pipes. Iron is much harder than bronze. * Modern Age (1 CE – Present) – main metals are iron‚ aluminium and steel‚ which were used for pipes‚ buildings‚ transport and electrical cables. This is the age where technology of iron and steel improved. Around the 1880’s‚ there was a significant move towards new alloys and metals‚ including tungsten steel
