How it works
This heat transfer graphic organizer asks the same three questions of conduction, convection and radiation. The answers line up across the page, so the differences between the three are easy to see.

What all three share
In every kind of heat transfer, heat flows from the hotter place to the cooler one, and it keeps flowing until both are at the same temperature. What changes from kind to kind is what carries it, so that is the question to ask of any example.
- Real scenes mix the three. A campfire shows them all at once, which makes it a good subject for the one-scene sheet.
- Convection needs something that can flow, so it is the usual way heat moves through liquids and gases.
Questions and answers
What are the three types of heat transfer?
Conduction, convection and radiation. Conduction passes heat between things that touch, convection carries it along in a moving liquid or gas, and radiation sends it as electromagnetic waves, which can cross empty space.
What is an example of each type of heat transfer?
A warm hand on a cold glass loses heat by conduction. A fan blowing warm air across a room moves heat by convection. The Sun warms the Earth by radiation. The filled-in sample uses these three.
What is the difference between conduction and convection?
In conduction the material stays where it is and heat passes from particle to particle; it is the main way heat moves within a solid. In convection the heated liquid or gas itself moves and takes the heat with it.
