La ciencia del agua, ¡el líquido más asombroso!

This 14-week course will provide an engaging foundation to elementary science by focusing on the amazing science of water. The class will begin by covering the characteristics of mass and volume and the practical aspects of measurement.  A running theme throughout the course will be the physical and chemical properties of water.  We will measure the density of water and compare this to other liquids. The density of objects relative to water and how that relates to if the objects sink or float will be examined. The importance of water as a universal solvent for many solids to dissolve into and make solutions will be addressed, as will its importance in chemical reactions. The course will cover the states of matter, phase transitions, and the significance of thermal energy in these transitions. In addition, students will learn about the force of surface tension and how this force can be used to cause motion. The ability of water to be absorbed by certain materials and its ability to overcome gravity and climb up paper and trees will be examined in siphoning and chromatography. In addition, the presence of water on our planet and in the solar system will be covered. Along the way, students will be exposed to the scientific method, the metric system, fun activities, STEM projects, and inquiry-based science. The live classes will include interesting demonstrations.
