Which Candle Burns the Fastest?

Which Candle Burns the Fastest? | Science Fair Projects | STEM Projects
Let's see which candle color burns the fastest! We want to eat the birthday cake sooner! We'll light five candles, one red, one white, one yellow, one purple, and one blue, and time how long it takes each to burn.


The hypothesis is that the white candle will burn the fastest.

Method & Materials

You will set up the candles four inches apart, mark a line one inch down from the wick on each candle, light them all at once, and time how long it takes each to burn.
You will need a ruler, stop watch, black marker, candles, candle holders, and matches.


We found out that the fastest burning candle was the yellow one. Therefore, our hypothesis was incorrect.

Why do this project?

This science project is interesting because it shows how color can affect the burning time of a candle.

Also Consider

Variations to consider include making the mark on the candle two inches down instead of one inch down, and trying other brands and colors of candles.
