Students can develop portfolios or collections of their work demonstrating their classroom-based performance. Portfolios emphasize the student's role in constructing understanding, support cooperative learning, and are effective.
Wind is the motion of atmospheric air measured relative to the rotating Earth.
It is the sun's energy that supplies the forces to move air. There are secondary circulations caused by land and oceans, and tertiary circulations caused by local topography. Winds are caused by the temporal variations in air temperature and air pressure. Children plan and carry out investigations. Children communicate using a variety of methods.
