energy
Our Standard Goals for this Unit:
WE WILL KNOW...
-When warmer things are put with cooler things, the warmer things lose heat and the cool things gain it until they are all at the same temperature.
-A warmer object can warm a cooler object by contact or by distance.
-Conduction is the transfer of thermal energy between things that are touching.
-Conduction happens with one object. (For example, thermal energy can be conducted through the handle of a metal pot.)
-Convection is the movement of thermal energy by the movement of liquids or gases.
-Convection in the oceans and atmosphere helps to move thermal energy around Earth, and is an important factor influencing weather and climate.
-Radiation is the transfer of energy by electromagnetic energy on Earth. Part of this energy, light, is used by producers to make food.
-Radiation can also happen in other circumstances, like sitting in front of a fireplace.
-Heating and cooling can cause changes in the properties of materials, but not all materials respond the same way to being heated and cooled.
-Heating and cooling cause changes in the properties of materials, such as water turning into steam by boiling and water turning into ice by freezing.
-Many kinds of changes occur faster at higher temperatures.
-Some materials conduct heat much better than others, and poor conductors can reduce heat loss.
