Unit+3.+Energy+-+Sun+and+Earth

=Unit 3. Energy: Sun and Earth= //**Anticipated Length of Unit **// //Approximately 57, 50-minute classes //

//Since energy is the source of all life on Earth, sustainable and renewable energy sources that balance the needs of both ecosystems and human activity are essential. In this unit students are introduced to basic energy concepts as they design their own thermometers. The Earth's energy budget and energy technologies that can make direct use of energy from the Sun are studied during labs and and design projects. Students will explore passive solar energy technology tand use Google Earth to explore the potential of wind as a possible source of energy. Measuring the electrical output of wind turbines in order to determine the best blade designs leads into a case study of a wind energy capture design problem on top of a Manhattan building and to test methods of enhance the energy that can be captured from the wind, students will test arrangements of small scale wind turbines that mimic wind dependent systems in nature. //
