Candles burn slowly due to the fact that the warmth from the fire must first melt the wax before it can burn the wick. Candles differ in color, shape and also size and also candle wax is make from a range of materials, including gel and animal fats. These differences can reason candles come burn at different rates. Science tasks can check out whether color, temperature, material or positioning will influence a candle’s burn rate.

Determine whether the shade of a candle affects its burn speed. Usage at the very least two of four different colors of candle that are the exact same brand, material and also shape. Mark a line about one inch under from the optimal of every candle. Light the very first candle and, utilizing a stopwatch, time just how long it takes the wax come burn down to the line. Repeat for the 2nd candle of the very same color and average the results. Repeat the experiment for the remaining colors the candles. Determine why some colors would burn much faster than others.

Experiment v temperature to recognize whether a room temperature candle will certainly burn faster than a frozen candle. Gather six identical candles. Ar two in the freezer for 24 hours and also leave the rest in the room you’ll be experimenting in because that the exact same amount of time. Light two candles at room temperature and also time just how long they burn. This establishes a baseline for your experiment. Climate light a frozen and also a room temperature candle at the very same time. Leaving them to burn until they go the end on their own. Repeat burning for the 2nd candles and average the times. Identify why one candle burns faster.

Determine whether the material used to make a candle will influence how fast it burns gather at the very least three different species of candles, such together beeswax, paraffin and also gel. Uncover candles of the same shape, size and color. Irradiate the first candle and time just how long it burns. Repeat v the other materials and also time those together well. Repeat the experiment a 2nd time and also average each result. Recognize which type of candle shed the fastest. Research how each form of candle is make to supply a reason for her results.

Experiment to determine whether heaviness will affect how fast a candle will burn. Bend one finish of 2 pieces the wire right into a circle to type a base. Bending the various other one so that a date of birth candle fits into it pointing up and also another one fits pointing down. Weigh each candle in that is base. Irradiate the upright candle and leave it to burn for one minute. Watch the color, shape and size that the flame. Placed out the flame and weigh the candle in that holder. Determine just how much mass was lost in burning. Place the downward dealing with candle into a foil pan and repeat the experiment. The candle need to be at an angle of about 70 levels from horizontal. If the edge is too steep, the dripping wax will placed out the flame. Keep in mind which candle shed faster and also whether the colors and also shapes were different. Position a candle horizontally too or repeat the experiment, place the candles in a jar and enabling them come burn completely. Determine whether the burn rate changed inside the jar.
