candle burn slowly because the heat from the fire must an initial melt the wax before it can burn the wick. Candles vary in color, shape and also size and also candle wax is make from a variety of materials, including gel and also animal fats. These distinctions can cause candles come burn at different rates. Science jobs can explore whether color, temperature, product or placing will affect a candle’s burn rate.

Determine whether the shade of a candle affects its burn speed. Usage at least two the four various colors of candle that room the exact same brand, material and also shape. Mark a line around one inch down from the peak of each candle. Irradiate the an initial candle and, utilizing a stopwatch, time exactly how long it takes the wax to burn down to the line. Repeat for the 2nd candle that the same color and also average the results. Repeat the experiment for the staying colors that candles. Recognize why some colors would burn quicker than others.


*

Experiment through temperature to determine whether a room temperature candle will burn quicker than a frozen candle. Gather six similar candles. Location two in the freezer for 24 hours and leave the rest in the room you will do it be exploring in because that the very same amount of time. Light 2 candles at room temperature and also time just how long they burn. This develops a baseline for your experiment. Then light a frozen and a room temperature candle in ~ the very same time. Leave them to burn till they go the end on your own. Repeat burning because that the 2nd candles and also average the times. Identify why one candle burns faster.


*

Determine even if it is the product used to do a candle will affect how rapid it burns gather at least three different varieties of candles, such as beeswax, paraffin and also gel. Uncover candles of the exact same shape, size and color. Irradiate the very first candle and also time exactly how long the burns. Repeat through the other materials and also time those as well. Repeat the experiment a second time and also average every result. Determine which type of candle shed the fastest. Research exactly how each type of candle is do to it is provided a reason for her results.

Experiment to recognize whether heaviness will affect how fast a candle will burn. Bend one finish of two pieces the wire right into a one to form a base. Bending the other one so that a birthday candle fits right into it pointing up and another one fits pointing down. Sweet each candle in that is base. Light the upright candle and leave it to burn because that one minute. Watch the color, shape and size of the flame. Placed out the flame and weigh the candle in that is holder. Determine exactly how much mass was lost in burning. Ar the downward facing candle into a foil pan and repeat the experiment. The candle should be in ~ an edge of around 70 degrees from horizontal. If the angle is also steep, the dripping wax will placed out the flame. Note which candle melted faster and whether the colors and also shapes were different. Position a candle horizontally also or repeat the experiment, put the candle in a jar and enabling them come burn completely. Recognize whether the burn rate adjusted inside the jar.
