Welcome to Science Buddies,

You can view these websites to gain additional background knowledge before beginning: https://www.explainthatstuff.com/candles.html
https://candles.lovetoknow.com/Do_White ... ed_Candles

Unfortunately, I could not find a Science Buddies experiment to match your project. However, once you begin looking at those websites, you should be able to begin. A few things you could do/ keep in mind: Make sure the sizes of the candles are very close or the amount of time needed to burn the candle will vary. Using the candles from the same brand may be a good controlled variable. You could also designate a certain length that you want to burn the candle. For example, you could mark the candle one inch from the top and time how long it takes to reach that mark. I would recommend at least 2 trials of each candle color. 3 or more trials would be best. I would also recommend at least 5 different colors, one of them being white.

Hope this helps,
Science Buddies Expert
