AIM: I am carrying out an investigation to see which alcohol is the best fuel. I will do this by experimenting with different alcohols and setting them alight and measuring different factors. I will analyse all my results and try to discover patterns‚ which should help me to conclude which alcohol is the best fuel. PLAN ==== This is how my experiment will be set out: ========================================== Keeping this experiment a fair test ===================================
