Convection in a Pan

Students watch a demonstration using a plastic bag and a hair dryer to create a hot air balloon. After the demonstration, they discuss the results and whether or not hot water behaves the in the same manner as hot air. They conduct their own experiments using soapy water in a pie pan and heating it with a candle. After observations are recorded, they compare the experiments and discuss how this relates to what is going on in the mantle of the Earth.

Hi, I was recently hired as a middle school science teacher in Newark, NJ. I received a call on a Friday and was asked to begin the following Monday. As a new teacher, and with only 3 days to prepare, I was really feeling the pressure. The school requires 2 weeks of lesson plans every Sunday, so I began searching the web for help. Thank goodness I found Lesson Planet. I still use the site everyday to form great lessons and activities for the kids.
