Convection

Today's learning target: Describe how heat transfers by convection.

Students read a short reading about convection. As they read, they completed a graphic organizer writing down important details (definition, characteristics, examples, and nonexamples). Once student finished reading, I showed an excellent clip that describes convection. Copy and paste the link below to check it out:

The next time we meet, our class will discuss our notes.

Big Idea: Convection is a form of heat transfer in a fluid by circulating currents. Air that is heated becomes warm and less dense which makes it rise. As this air moves further away from the heat source, it cools. Cooler air is less dense which forces it to sink back towards the heat source where the process begins again.


Practice: None
