One of the first things I learned in this unit was conduction. Conduction is the transfer of energy by direct contact. One example of conduction is pancakes on a griddle. The second thing I learned was radiation. Radiation is the transfer of heat from one object to another without the use of matter. We get most of our radiant energy from the Sun here on Earth. The last thing I want to talk about is heat, the transfer of energy from warmer matter to cooler matter. Heat is transfered by conduction, convection, and radiation.
What I liked most in this unit was the popcorn lab where we cooked popcorn 3 ways and identified if they were conduction, radiation, or convection. We got to taste-test afterward! What I liked the least was doing tests and study guides.
In this unit we also learned about insulators and conductors of heat. The only conductor mentioned was metal. Why is water a conductor of electricity and not heat?
