Students will be able to:
use information from videos from the internet, supplementary texts, and classroom discussions to
-interpret from everyday examples the states of matter and explain how energy is added or released to change state (i.e. lake, cooking, glacier, snow, clouds or steam) .
-recognize that adding heat to or removing heat from a system may result in a temperature change and possibly a change of state
-describe and illustrate what will happen to the heat and kinetic energies within a glass of ice water if left out in a room vs. being left in a freezer and/or the refrigerator.
The do now was to describe and illustrate what happens to the heat and kinetic energies within a glass of water left out in a room verses being left in a freezer and/refrigerator.
Students watched a BrainPop movies on states of matter and on matter changing states. They learned that:
-solids turn to liquids when heat is added, the temperature at which a solid melts is its melting point. The molecules begin to move faster, and the kinetic energy increases.
-liquids turn to gas when heated; the process is called vaporization.
-some solids, such as dry ice, changes from a solid directly to a gas in a process called sublimation.
Remember science fair plans are due!
