  Solar System Maker

  Solar System Maker. This fun game allows students to create and print their own solar systems. They can specify planets, planet names, planet sizes, planet order, and whether or not planets have rings or moons. This activity can be copied directly into your Google Classroom, where you can use it for practice, as an assessment, or, to collect data.

  From Sand to Silicon: The Making of a Chip

   · Common sand has a high percentage of silicon. Silicon—the starting material for computer chips—is a semiconductor, meaning that it can be readily turned into an excellent conductor or an insulator of electricity, by the introduction of minor amounts of impurities: Melted silicon. In order to be used for computer chips, silicon must be purified so there is less than one alien atom per ...

  What is Solar Energy How Do Solar Panels Work? | SunPower

  When photons hit a solar cell, they knock electrons loose from their atoms. If conductors are attached to the positive and negative sides of a cell, it forms an electrical circuit. When electrons flow through such a circuit, they generate electricity. Multiple cells make up a solar panel, and multiple panels (modules) can be wired together to form a solar array. The more panels you .
