Heat the bottom of the candle and secure it to a cardboard square on your lab counter. Light the candle and allow it to burn for several minutes. Note any changes. Briefly describe the burning candle.

When Columbus got here in 1492 when they were on the ship they had seen a light. They described it as a a small wax candle

One Quart Zip-Lock bag and fill it with 20mL of Hydrochloric acid, take a taped off Easter egg and fill it with 5.15g of baking soda. Insert egg in corner of bag and close bag. When ready to deploy flick egg to release baking soda into the acid to create a gas to fill the bag.

Candles are a convenient way of providing light and heat when no electricity is available. They are normally made from paraffin wax with a wick in the middle. Candles can also be made from soy wax or other plant wax, animal fat or bee wax. Wax acts as a fuel to keep the candle burning. The wick has to be an absorbent twine with

water, 2 tsp. coconut oil, about 15 drops essential oil, and a few drops of food coloring (depending on the color I wanted), ¼ cup Epsom salt, 5 bowls, and molds to put the mixture into. To create the different halves, I took half of each ingredient into separate bowls and added either ¼ cup lime juice or ¼ cup citric acid. First, I combined the baking soda, corn starch, and Epsom salt into a bowl. If I was using the citric acid, I combined that into the same bowl. Next, I combined my water, coconut oil, essential oil (optional), and food coloring (optional) into a different bowl. If I was using the lime juice instead of the citric acid, I would combine it into this bowl. It is very important you keep your wet and dry ingredients separate. Then, I slowly put a few drops of the wet mixture into the dry mixture and stirred. You want to put a few drops, then stir; add a few more, and stir again. You must do this step slowly to prevent any reactions happening between the citric acid and the baking soda. During this step, I discovered that the side with lime juice was much moister than the other side with citric acid. This made it difficult to mold the halves together because a slight reaction was occurring when I put them together. Next, I put the different mixtures into half a mold and stuck the halves together into the freezer for 2 hours. Then, I took the bath bomb and put it into a bowl full of warm water. Finally, I watched the reaction and recorded my

The Light bulb changed the lives of many people; it had a big impact on illuminating the night. The night was always dark until the light bulb was invented by Thomas Edison in 1879 and ever since then, the night has been able to be bright if people wanted it too. The story of the light bulb begins long before Edison patented the first commercially successful bulb in 1879; in 1800 Italian inventor Alessandro Volta developed the first practical method of generating electricity, the voltaic pile, made of alternating discs of zinc and copper, the pile conducted electricity when a copper wire was connected at either ended. An English inventor by the name of Humphrey

Break an Alka-Seltzer tablet into a few small pieces and drop them into the container one at a time. When the bubbles stop add more pieces of Alka-Seltzer to see it again.

The Cobb Museum had a collection of Old World oil lamps. One lamp was cream colored and teardrop shaped. The top was adorned with a thin u-shaped decoration. Small etched circles added a decorated touch. The top of the lamp had a small looped handle. At the back of the case there was an interesting oil lamp. It was tan colored with hints of red. The handle looked like the back fin of a whale. Next to the spout was a floral design. Two gazelles with long, thin horns graced the sides of the lamp (http://www.cobb.msstate.edu/museum/). The lamp that stood out the most was a black lamp with four spouts from Rome (Cobb). It was the only displayed lamp with multiple spouts. Two of the spouts were missing, but it was obvious where the missing ones would have been. The two remaining spouts had wide openings. The lamp had protruding triangles between each spout to give the lamp a diamond shape. All of the oil lamps in Cobb were varied and unique.

The students were able to relit the candle because they followed the stream of smoke was followed and carbon vapors and relights the already-hot wick. No experiment is perfect, during the candle lab many errors occurred. Some of the common errors that occurred during this lab were human, random, and systematic error. All of these errors could change the lab results.

9. put one of the thermometers on the rock and the other in the water/sand/gravel mix.

To make a bath bomb you need baking soda, corn starch, citric acid, Epsom salt, food coloring, a plastic mold, an essential oil for scent, and castor oil. Mix the dry ingredients together by adding ½ cup baking soda, ¼ cup of corn starch, citric acid, and Epsom salt. In a separate container mix the wet ingredients. For the wet mixture add three tablespoons castor oil, food coloring drops, one tablespoon essential oil, and one tablespoon of water. Mix well. SLOWLY add the liquid ingredients to the dry to ensure that the solution does not activate. Mix well. Tightly pack the plastic mold with the mixture, and let the molds sit over night or until ready for use. When you are ready to use the bath bomb gently tap both sides of the mold to release

A plastic mold is the only tool you really need to have to make your own citrus bath bombs. Molds can be found on Amazon or you can use a plastic ball ornament. You can also use any other item you might have at home for a mold for this project.

This experiment was conducted to determine if the light of a glow stick can be affected by the temperature of water. In this the researcher will try to find what temperature of water makes a glow stick glow brighter and how long it will stay lit. By proceeding in the experiment, the data collected proved the hypothesis to be correct. Warmer water caused the glow stick to glow brighter than it had before. On the other hand, the beaker with colder water made the stick stay lit longer and the room temperature water didn’t affect the glow stick as much.
