_____ ______ Before After Observations: At the very end the water… _____ ______ Before After 2. 5. candle Erlenmeyer flask 1. 3. 6. 4. water beaker Observations: At the very end the water… When the candle is lit… Prediction: Now let’s see what happens! The demo works TONS easier this way! Changes made to the lesson from the original: Materials- 1,000 mL beaker, tea light candle, 1,000 mL erlenmeyer. Keep the mouth of the erlenmeyer submerged during the whole demo. As always, practice beforehand, and be safe with the flame. Explanation: candle was lit air inside heated, expanded air escaped; (less air inside than before) candle went out air inside cooled and contracted air pressure outside pushed water in The reason this happened is because… Why I think this happened:
