Have you ever wondered whether a candle burns more quickly on a hot day, than on a cold day? Or is it the other way around? This science fair project was carried out to compare how quickly a candle will burn at different room temperatures. The experiment was done by measuring how much of a candle will melt in 30 minutes when placed in an environment with surrounding temperatures of 20°C, 25°C and 30°C.

1. For this science fair project, the independent variable is the temperature of the room, i.e. 20°C, 25°C and 30°C. The dependent variable is the length of the candle after it has burned for 30 minutes. This is determined by measuring the length of each candle with a ruler before it is lit and after it has burned for 30 minutes. The constants (control variables) are the type and length of the candle, the diameter of the candle and the time the candle is allowed to burn. 2. Using the ruler and caliper, the length and the diameter of .....
