Students come to understand static electricity by learning about the nature of electric charge, and different methods for charging objects. In a hands-on activity, students induce an electrical charge on various objects, and experiment with electrical repulsion and attraction.
Students learn about wind as a source of renewable energy and explore …
Students learn about wind as a source of renewable energy and explore the advantages and disadvantages wind turbines and wind farms. They also learn about the effectiveness of wind turbines in varying weather conditions and how engineers work to create wind power that is cheaper, more reliable and safer for wildlife.
Students learn the history of the waterwheel and common uses for water …
Students learn the history of the waterwheel and common uses for water turbines today. They explore kinetic energy by creating their own experimental waterwheel from a two-liter plastic bottle. They investigate the transformations of energy involved in turning the blades of a hydro-turbine into work, and experiment with how weight affects the rotational rate of the waterwheel. Students also discuss and explore the characteristics of hydroelectric plants.
Students build their own simple conductivity tester and explore whether given solid …
Students build their own simple conductivity tester and explore whether given solid materials and solutions of liquids are good conductors of electricity.
Students learn how engineers transform wind energy into electrical energy by building …
Students learn how engineers transform wind energy into electrical energy by building their own miniature wind turbines and measuring the electrical current it produces. They explore how design and position affect the electrical energy production.
To explore different ways of using solar energy, students build a model …
To explore different ways of using solar energy, students build a model solar water heater and determine how much it can heat water in a given amount of time. Solar water heaters work by solar radiation and convection.
