Candle Experiment
In science today we placed a candle in a petri dish with water inside. Then we lit the candle and and placed a cup over the top of the candle to lock up the oxygen.
Aim - To see what happens to the water level when the candle is covered.
Hypothesis - I think the candles flame would go out because the candle was air trapped.
Results - The candle went out and the cup sucked up to the petri dish, so if you lifted the cup the petri dish would be sucked to the bottom.
Conclusion - The water rose because it was heating up. The flame was using all the oxygen and eventually it was all gone and the cup stuck to the petri dish.
