Make a Solar-Powered Water Fountain!
 
Making mathematical connections to other disciplines has become an increasingly important instructional strategy for teaching middle school (grades 6-8) students at the New Birth Christian Academy. As a middle school math teacher and a firm believer that mathematics should be taught in context, I am proposing the use of a solar-powered water fountain as a practical way of giving my students a deeper understanding of the mathematical ideas (algebra, number sense, geometry & measurements and data analysis) linked to the application of solar electricity using photovoltaic (PV) modules. This project will provided hands-on experience that is engaging, enjoyable and interactive. By responding quickly to sunlight, students will immediately see, hear and touch the effects of solar electric PV module as it moves the water.
 
The fountain will use a solar PV module (40 watts) to power a direct current (dc) 12V water pump and will allow for interaction so that students can test the effects of shading, orientation and tilt angle of the solar module. Students will: (1) conduct experiments relating to the use of photovoltaic modules in the generation of electricity; and (2) design and install a solar powered water fountain while integrating the used  mathematics (geometry & measurement, data analysis, number sense, and algebra) and other disciplines (Science, Technology, Art, Social Studies, and Language Arts).
