Hypothesis: when melted, a candle will lose mass and become lighter.
Aim: to determine if candles lose mass when burnt and how much mass is lost from different candles when melted
Method:
a) Equipment:
5 different candles
Centigram
Timer
Plastic plate
Matches
b) Method:
1. Collect the equipment and set it up
2. Burn a candle for one hour and calculate mass loss at 10 minute intervals in percentage mass loss
3. Repeat step 2 for the other four candles
4. Observe the changes of the candles and other notable points of the experiment
5. Record results in a table and also plot the results on a graph
6. Clean up experiment area and put away equipment
