Boiled Ice

You’ve probably seen that graph that shows what happens when frozen water is heated and changes state until it’s a gas (http://www.kentchemistry.com/links/Matter/HeatingCurve.htm). If so, you may have thought something like “Wow, this is beautiful, but there’s a LOT more info here that I can understand.”

In this lab, we’ll actually take class time (3 days), give students ice that they heat until it melts into a liquid and then later becomes a gas, while they take temperature readings every 2 minutes. Then they’ll graph their results, and what they’ll see is that beautiful graph that they completely understand.

Student Handout, PPT and Teacher Notes (in the notes area of the ppt)

UPDATE- here’s a super-simple handout I made for students. It should simply things, and save time. ALSO- second time around I did one setup of this for the class instead of each group having their own.
