Birthday Candle Mystery
Something very “mysterious” and unexpected happens when you pour a little water into a pan, set a birthday candle in the middle of it, light it, and cover it with a glass beaker. This activity allows your students to wrestle with a surprise ending that, not only did they not expect, they will be challenged to explain. This is science the way it was meant to be taught.
UPDATE- here is a much easier way to do this demo! See notes area of the ppt.
