Data & Results

📊 Data

The following table shows the rotational speed data collected during the experiment:

Number of Candles	Trial 1 (RPM)	Trial 2 (RPM)	Trial 3 (RPM)	Average (RPM)
1	0	0	0	0.0
2	0	9	13	7.3
3	18	13	15	15.3
4	22	22	25	23.0

Note: RPM = Rotations per minute

👁️ Additional Observations

• Temperature of air above candles (if measured): _____°C
• Time for carousel to begin spinning after lighting candles: _____ seconds
• Weather conditions during experiment: _____
• Room temperature: _____°C

📈 Results

After conducting the statistical analysis of the data collected, the results show a significant increase in rotation speed with more candles. The carousel did not rotate with 1 candle, but showed increasing rotation speeds as more candles were added.

The carousel achieved the highest rotation speed with 4 candles, averaging 23.0 RPM. The lowest speed occurred with 1 candle(s), averaging 0.0 RPM.

The data demonstrates a positive correlation between the number of candles and rotation speed. The relationship appears to be non-linear, with the most significant increase occurring when going from 2 to 3 candles. The percentage increase in speed from 1 candle to 4 candles was N/A (starting from 0).

🔍 Key Findings

• The relationship between number of candles and rotation speed appears to be non-linear, with accelerating increases as more candles are added
• The most significant increase occurred when going from 2 to 3 candles (from 7.3 to 15.3 RPM, a 109.6% increase)
• Data consistency across trials: Moderate variation observed, particularly in candle 2 and 3 trials, with candle 4 showing the most consistent results
• One candle produced no rotation (0 RPM), indicating a minimum threshold of heat energy is required
