Chemistry Period 8 Title: Observations of a Candle
Research Question: Observations are needed to explain the physical world.
Introduction: Candles are very useful in science and society. They help provide light and fire for people. Candles are made out of primarily wax. Wax helps a candle burn. A candle runs on a flame and fire needs oxygen to burn and keep the flame alive. In this lab, we had to observe a burning candle. We did this to see the physical …show more content…
First, we had to observe the candle before it was lit. This was done to see how it changes after it is lit.
2. Second, we had to light the candle. The candle was stored inside of the petri dish with aluminum foil inside of it.
3. Then, we observed the lit candle. We had to watch the candle burn for a couple of minutes. We had to see how the candle has changed from before it was burnt to this point.
4. Then, we had to acquire a 250-mL beaker and fill it with water just half way. We then had to put the bottom of the beaker right on the flame for one second. We did this so we can observe what happens to the bottom of the flask once it hits the flame.
5. Next, we had to pour the water into the petri dish. Finally we put the 500-mL flask over the candle. We had to observe what happened to the candle during that time period. We did this so we can see what happens when a flame is cut from oxygen.
Results:
Table A- Observations of the unlit candle. Table B- Observations of the lit candle. Table C- Observations about the beaker of water having been exposed to the candle flame. Table D- Observations of the Erlenmeyer flask and the lit
