Students relate the process of precipitation to global warming. There are certain circumstances and appropriate compositions of clouds that allow precipitation to develop. Meteorologists use special tools to research and monitor precipitation, and provide the public with severe storm watches and warnings. 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.
Children propose explanations and solutions, and build a store of concepts. Children raise questions. Children use observation. Children critique their science practices.
