Conduction and Convection
Two flasks hold colored water, one yellow and the other blue. Set the starting temperature of each flask, choose a type of material to connect the flasks, and see how quickly the flasks heat up or cool down. The flasks can be connected with a hollow pipe, allowing the water in the flasks to mix, or a solid chunk that transfers heat but prevents mixing.

LEARNING OBJECTIVES:
- Observe that heat flows from warmer objects to cooler ones until temperatures equalize.
- Measure heat transfer via conduction and convection.
- Observe that metals are better conductors than nonmetals.
- Determine that hot fluids tend to rise while cold fluids tend to sink.
- Compare conduction and convection.
VOCABULARY:
- conduction, conductor, convection, insulator
