Wax Melting Experiment
Wax Melting Experiment September 20, 2010 Janine Nifco
Problem: At what temperature (degrees Celsius) does wax melt at?
Hypothesis: The class hypothesis is that wax melts at 60 degrees Celsius
Tools/Materials: Beaker, wax, heating plate, thermometer, pencil/paper to record things
Procedure: 1. Clear you area and make sure it is a safe area to work in
2. Prepare everything (thermometer in wax, wax in beaker, beaker on heating plate)
3. Turn on heating plate and record the temperature every 15 or 30 seconds or every minute (do it to your liking)
Conclusion/Results: The class started off well with the first chart but after 240 seconds, the beaker broke and the wax started slowly oozing out. We quickly realized and changed the wax into a different beaker and started the experiment again but started at a higher temperature. The wax then slowly melted and we figured out that wax melts at 70 degrees Celsius.
