Making Observations and Recording Data for Solar Powered Water Pumping
Students use a solar module and water pump to test how quickly one cup of water can be pumped.
Students use a solar module and water pump to test how quickly one cup of water can be pumped.
Students first explore with 0.5 Volt solar cells to see whether adding cells to a circuit increases the amount of water pumped by a small pump. They are introduced to parallel and series wiring. They then design and carry out a formal experiment to test...
Through a series of inquiry activities, students will discover the properties of the chemical reaction of dissolving CaCl 2 in water, the effect of stirring, and of adding baking soda and sodium polyacrylate crystals. Once initial data is collected,...
Students will learn the basics of solar power and the difference between photovoltaic solar power and passive solar power. They will also learn the pros and cons of solar power and be able to describe the advantages and disadvantages of using solar power...
Now that students are familiar with how mechanical electricity generation works, they will build a wind turbine powered by a box fan. Different teams will test different turbine variables to see how the amount of electrical power is affected. After each...
Students use a solar module and other materials in conjunction with a water pump to test how quickly one cup of water can be pumped.
With all the pieces in place, this Unit’s final lesson asks students to code a spreadsheet that calculates and mathematically predicts the environmental impacts of different energy sources and strategies over a 50 year timespan. Divided into five...
Students will plan and condict an investigation into solar photovoltaic technologies to determine what variables affect the output of panels. They will calculate and compare their exploration of solar panels to their previous investigation of wind turbines...
Students will work with local government staff or another local energy professional to propose a way to create enough solar power energy to supply the annual energy needs for a real building. Students will be provided with on-site options, and will...
Students will explore ways that the sun can be used to heat water and the variables involved in the efficiency of using the sun to heat water for use in homes or businesses. They will determine this through taking measurements of their solar water heaters...
