Photovoltaic Efficiency
Read the Fine Print
Educational Use
Rating
0.0 stars

Through a series of four lessons, students are introduced to many factors that affect the power output of photovoltaic (PV) solar panels. Factors such as the angle of the sun, panel temperature, specific circuit characteristics, and reflected radiation determine the efficiency of solar panels. These four lessons are paired with hands-on activities in which students design, build and test small photovoltaic systems. Students collect their own data, and examine different variables to determine their effects on the efficiency of PV panels to generate electrical power.

Educational Use
Rating
0.0 stars

Student teams measure voltage and current in order to determine the power output of a photovoltaic (PV) panel. They vary the resistance in a simple circuit connected to the panel to demonstrate the effects on voltage, current, and power output. After collecting data, they calculate power for each resistance setting, creating a graph of current vs. voltage, and indentifying the maximum power point.

Pump It!
Read the Fine Print
Educational Use
Rating
0.0 stars

Pumps are used to get drinking water to our houses every day! And in disaster situations, pumps are essential to keep flood water out. In this hands-on activity, student groups design, build, test and improve devices to pump water as if they were engineers helping a rural village meet their drinking water supply. Students keep track of their materials costs, and calculate power and cost efficiencies of the prototype pumps. They also learn about different types of pumps, how they work and useful applications.

Solar Water: Heat it Up!
Read the Fine Print
Educational Use
Rating
0.0 stars

Students explore energy efficiency, focusing on renewable energy, by designing and building flat-plate solar water heaters. They apply their understanding of the three forms of heat transfer (conduction, convection and radiation), as well as how they relate to energy efficiency. They calculate the efficiency of the solar water heaters during initial and final tests and compare the efficiencies to those of models currently sold on the market (requiring some additional investigation by students). After comparing efficiencies, students explain how they would further improve their devices. Students learn about the trade-offs between efficiency and cost by calculating the total cost of their devices and evaluating cost per percent efficiency and per degree change of the water.

Rating
0.0 stars

People use energy in all aspects of their lives for cooking, lighting and entertainment. Much of this energy use takes place in buildings, such as our homes. To save money and reduce the impact on our environment, many people are reducing their energy use. One way is to hire engineers to perform home energy audits to understand the ways we use energy and identify ways we can conserve energy. In this activity, students act as energy conservation engineers and identify the ways energy is conserved or wasted. They also learn many ways to personally conserve energy everyday.
