Use a technological problem-solving process to design, construct, and evaluate the reliability of a device to detect static electrical charges, such as an electroscope. |
| (f) |
Explain, with reference to electron transfer, the production of static electrical charges in some common materials such as flannel, fur, wood, plastic, rubber, and metal. |
| (g) |
Describe the operation of technologies that have been developed based on scientific understanding of static electric charge and discharge (e.g., air filters, fabric softeners, lightning rods, automotive painting, plastic wrap, grounding straps, Van de Graaff generator, and photocopiers). |

Outline the contributions of people from various cultures to modern understanding of static electric charge and current electricity (e.g., Thales, Robert Boyle, Benjamin Franklin, Michael Faraday, Nikola Tesla, Georg Ohm, Alessandro Volta, André-Marie Ampère, James Wimshurst, and Robert Van de Graaff), and past and present careers that require an understanding of static electric charge and current electricity. |
| (i) |
Identify dangers to the human body associated with static electric charge and discharge, and current electricity, and discuss how technologies such as grounding straps, lightning rods, grounded plugs, fuses, and circuit breakers are designed to minimize such dangers. |
| (j) |
Design and safely conduct an investigation to determine the resistance of various materials such as copper wire, Nichrome wire, graphite, rubber tubing, wood, glass, distilled water, and ionic solutions to electric current. |
