How Heat Is Transferred
Essential Question: How Is Heat Transferred?

Nathaniel Weeldreyer, Tayib Rose
By: Jacob Stabler, Mikayla Grieser,
Conduction
Convection
The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
*The movement caused within a fluid of the tendency of hotter

* less dense material to colder and denser material under the infulence under the gravity
* Which consequently results in transfer of heat

Bibliography
Warming your hands on a heating vent for example.
Radiation
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
Essential Question

Real world examples:
Picture Page
Conduction: using a heated blanket to get warm.

Convection: Putting wet shoes on a heating vent to dry them faster.

Radiation: Lying out in the sun to get a tan.

Convection current: In the oven air is moving around due to the difference of temperature.

Heat: The sun burning the sand or a warm
fireplace.,
