What Color Candle Burns the Fastest?

My topic was about burning candles. I wanted to find out what color candle would burn the fastest. My hypothesis stated that, if I burned five candles, one red, one white, one orange, one pink, and one blue, then the white one would burn the fastest. Why did I choose this as my experiment? Well I love to burn candles and wanted to know what colors to buy so that they would last longer.

Materials

The materials that I used were a , green marker, candles, and matches.

The variables that were kept the same were the candle’s brand, when we started to burn them, the length and width of the candle, room temperature, and distance between the candles. The only thing that was different was that the candles were different colors. To carry out my project I first set up the candles four inches apart. Then I marked a line half inch down form the wick on each candle. Then I lit them all at once. Next, I started timing how long it took each to burn. I stopped timing when the mark on each candle was gone. Finally, I recorded my data.

Each candle was spreaded apart and lit at the same time.

As you can tell the bright colored ones burnt the fastest. The light pink and the white was the slowest ones to burn.

Parents its Science Fair Time


Whitesburg School will hold its annual science fair on May 1, 2010 Each student is required to participate in this important learning experience. Student projects are to be completed at home independently by the student. All projects are to be brought to the school for display on May 1, 2010. We are asking you to assist your child in preparing his/her exhibit. Thank you for all your support. If any questions please call me.


Topics For Science Fair Projects

Engage Gear

Gears are used in tons of mechanical devices. They do several important jobs, but most important, they provide a gear reduction in motorized equipment. This is key because, often, a small motor spinning very fast can provide enough power for a device, but not enough torque. For instance, an electric screwdriver has a very large gear reduction because it needs lots of torque to turn screws, bu¬t the motor only produces a small amount of torque at a high speed. With a gear reduction, the output speed can be reduced while the torque is increased.

Engage Gear
Materials Needed: Two Nails, Glue, Thread Spools, Jar Lids, Card board, Sandpaper.





Glue the sandpaper strips around the edges of the lids and glue the spools to the bottom of the lids.











Push the two nails through the cardboard. These serve as the axels for your gear wheel.










Place a different size lid on each nail. Turn the lids using another thread spool as a handle.

Standards:

0507.Inq.1 Identify specific investigations
that could be used to answer a particular
question and identify reasons for this choice.

0507.Inq.2 Identify tools needed to
investigate specific questions.

Mini Lesson Plan

Make an Underwater volcano.

Materials needed: large glass jar, string, red food coloring, hot and cold water, paint brush, scissors, narrow neck small bottle.
















Hold the bottle by the loop of the string. Lower it gently into the jar of cold water.













Fill the small bottle with hot water. Add the food coloring to turn the water bright red.


















The hot red water rises from the bottle like smoke from an erupting volcano.




























This is what it looks like when using a large vase.

Science Behind It

Standards

Liquids can float and sink just as solid objects can. It all depends on something called " density." A substance with a lower density weighs less than the same volume of one with a higher density. An object or liquid will float only in a liquid more dense than itself.



You will need: Colored Water, Syrup, Vegetable Oil, Large Container, Selection of objects to float.



1. Carefully pour syrup into the container until it is a quarter full. It is easier if you pour the syrup over the back of a spoon.

2. Slowly pour the same amount of vegetable oil into the container. Then add the same amount of colored water.






3. The three liquids seperate into three layers and float on each other. Now add the objects you plan to float.







4. The objects float at different levels. They sink until they reach a liquid of a higher density than themselves. They float on that liquid.



Water is more dense than the oil but less dense than the syrup.
