Introduction In this lab I observed the burning of a candle very closely. I found out that the candle needs oxygen to burn‚ that it produces carbon dioxide similar to the way that my body produces carbon dioxide‚ and that a candle produces water as a second waste product.

Finally‚ I learned that neither the solid wax‚ nor the melted wax‚ nor the wick burns when a candle is lit. In fact‚ the

The Drill team has taught me the importance of persistence. I joined the drill team my Sophomore year of high school. My first year flew by. Everything was a novelty‚ and I loved the new styles of dance that I was learning. My second year of Drill Team was similar to the first. Things were still a novelty‚ but I was starting to catch onto concepts‚ routines‚ and schedules.

One of Milton’s strengths used in his epic Paradise Lost is his vivid imagery. He uses imagery not only for visual impact but also for reinforcing themes and characterization.
