Candles vary in color, shape and size and candle wax is made from a variety of materials, including gel and animal fats.
They can warm a room with their flickering displays of light, set a festive mood for the holidays and be literal lifesavers during power outages.
What do Candles Burn?
Assemble a clear glass canning jar, a cereal bowl, some molding clay and dye to color water. Place the clay in the bottom of the cereal bowl and then lodge the candle in the clay to hold it firmly in place.
Take some dark purple food coloring and add 3 tablespoons to a glass of water. Carefully light the candle and place the jar over the top so that it goes to the bottom of the water in the bowl. Notice that the candle goes out and the water level changes. The fact that the candle has gone out shows that it uses up air oxygen to burn and that the level of the water reflects the fact that water is a byproduct of combustion.
Making Candles Show fair-goers how candles are made. Buy candle wicks at your local hardware store, supermarket or online. You can make posters or a video that talks about the melting point of wax. Bring a hotplate and an old pan to melt the wax. You will need forms to pour your wax into.
You can use several different materials for your wicks, such as shoelaces, thread and jute string.
Then you can explain that the amount of wax absorbed by the wick influences its efficiency. Be very careful when handling hot wax because it can cause burns.
Sciencing Video Vault Burning Rates There is a hypothesis that white candles burn faster than colored ones. To test this, buy white uncolored wax candles, blue candles, green candles and other colored candles, all of the same shape and size. Put a large, visible timer on your display table and light the candles at the same time.
Have a large chart to record how long it takes for each candle to burn 1 inch. At the end of the fair, you can prove or disprove your hypothesis. Tips for a Good Project You should make your project interesting by using colorful posters or making interesting informative videos.
Models and and hands-on materials keep visitors interested. Also, be sure that your project and display are safe. Make sure that your electric supply can handle your hot plate and that you can safely pour out the wax from your pot. Candles can cause burns, so use caution when working with them.

be it. Although we recognize that science projects involving the burning of candles are often undertaken by elementary school students, the National Candle Association strongly discourages the use of candles by children, and does not recommend candle science projects for children under the age of 12, even with adult supervision.
