Science Prezi (Which Candle Burns Faster?)
Transcript of Science Prezi (Which Candle Burns Faster?)
By: Gabbi Ward Which Candle Burns Faster? Red or White? You will need:
~ Red Candle
~ White Candle
~ Measuring Tape
~ Timer Next, measure the candles down to like, two inches. Mark the two inches spot with a Sharpie. Video Part 1 Video Part 2 My expirement tests Chemcials.
The purpose for this experiment is to test the chemicals in colored and white candles.
The question is: Which candle burns faster, red or white? What is chemistry?
Chemistry is the science of matter, espically it's chemical reactions.
Chemistry is concerned with atoms and their interactions with other atoms, particuarly with the properties of chemical bonds. What happens when you light a candle? When you light a candle, the heat of the flame melts the wax near the wick. This melted or liquid wax is then drawn up into the wick by capillary action. The flame's heat vaporizes the liquid wax to produce water vapor and carbon dioxide (the same byproducts that humans produce when exhaling). Information from National Candle Association website & Wikipedia Step 2:
Observations & Research Step 3:
My hypothesis is that the white candle will burn faster. I think this because I think the red candle would have more dye in it to change it's color. The white has dye, but I think it has less than the red. So, since the white has less, I think it will burn faster because it doesn't have to burn up all the dye and chemicals. Experiment:
For my experiment, I will measure and mark the candles. I will light the candles and start the timer. When one of the hits the mark, I will stop the timer and see how long it took. Step 6: Collect Results
My results were that they were pretty much the same burning rate. At first, the red one was ahead but the white one caught up. At the end, the red one was just a tiny bit more burnt. My hypothesis was wrong. I think the red ended burning faster because of all the chemicals in it. So basically I predicted the opposite of what actually happened. If I were to further investigate this concept, I would do the same experiment again, only with a different colored candle. THE END!!!!!!!!! Steps of the Scientific Method (a.k.a how I will do this experiment) Steps of the Scientific Method (a.k.a What I am using for this experiment!) Step 1: Question/Problem Step 7: Conclude
Chemicals in candles are quite alike, to be honest. I would like to try it with different colored candles. It would be cool to do that and see what those results could be. They could same or different. Chemicals are just funny like that. Until next time! Fast Fact:
Did you know that the chemical element phosphorus was observed in 1669 by Hennig Brand? Prepared from urine, it was the first element to be chemically discovered! Fast Fact:
Uranium was named after the newly discovered planet Uranus.
