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.
