Burning Speed of Scented and Unscented Candles

Burning Speed of Scented and Unscented Candles | Science Fair Projects | STEM Projects
Do scented candles burn faster than unscented ones? Let's find out by comparing the burning speed of scented and unscented candles.

Hypothesis

The hypothesis is that unscented candles burn more quickly than scented candles.

Method & Materials

You will measure the height of the candles before and after burning them for 30 minutes, and compare the reduction in the candle's length.
You will need 5 unscented candles, 5 rose scented candles, 5 apple scented candles, a ruler, a caliper, a stopwatch, and a box of matches or lighter.

Results

The results showed that all candles became shorter by 25 to 30 mm in 30 minutes, with an average length of candle burned being around 27mm. This proves that the hypothesis that unscented candles burn more quickly than scented candles is false.

Why do this project?

This science project is interesting because it is a simple experiment that can be done with materials that are easily available. It also shows how the burning speed of candles is not affected by the scent.

Also Consider

Variations of this experiment can include comparing the burn rate of different colored candles, or comparing the weight of the candle instead of its height.
