Introduction Does the number of lit candles affect how high the water will rise inside the cover? The prediction that was used was if the number of candles does affect the height of the water, then as more candles are burned the water will get higher. The hypothesis was the number of candles does affect the height the water rises. Some background information in this experiment is that the water will rise when the oxygen is burned and there is space for the water to rise. Experimental Design In this experiment we had a dependent, an independent, and some control variables. The independent variable is the number of candles we lit and burned, and this was the independent variable because we changed how many candles were lit at one time. The dependent variable in this experiment was how high the water rose inside the cover, and this was the dependent …show more content…
First, a clear pan was filled with water, and re die was added to the water. 2. A blue plastic box was placed in the center of the water; a little bit of the plastic blue box was visible above the water. 3. 4 candles were placed on the plastic blue box. 4. One candle was lit of the four but all four were kept on the plastic blue tray the whole time. 5. A glass cover is placed over the candles, and the platform. 6. It took a little while, but soon the water started rising into the glass cover. 7. The data is recorded in a data table, and this experiment was replicated 3 other times. 8. The other candles were also later after the one candle was lit. the other 3 went in order form 2, then 3, then 4 candles lit at a time. 9. The average was found and the data was graphed.
