| 1. For this experiment, the independent variable is the type of candle used – unscented, rose scented and apple scented. The dependent variable is the reduction in the candle’s length after 30 minutes. This is determined by measuring the height of the candle before and after allowing it to burn for 30 minutes. The constants (control variables) are the length of the candle, the diameter of the candle, the allowed burn time and the room temperature. 2. The three types of candles are labeled according to their scents and numbered from 1 to 5 for each type. Their total ..... | ||
