수업 소개
This is a "Hands On" science class that continues the "What is Electricity" series. In this class the students will use their own voltmeter to learn how to measure electricity. The class is split into three sessions, each focusing on a major aspect of measuring electricity. Session 1: Measuring Voltage Explore the basics of a voltmeter Explain the three main aspects of electricity: Volts, Amps, Ohms Practice measuring battery to see how much life is left in them Explore voltage dropping as batteries die Explain Series vs Parallel for voltage Session 2: Measuring Amperage Review the Basics of the voltmeter Explain safety rules of measuring amperage Build a test set of conductive water and battery Explore measuring amperage as salt (conductivity) level increases Explain Series vs Parallel for amperage Session 3: Measuring Resistance Review the basics of the voltmeter Explain the concept of resistance Build a "homemade" resistor from pencil lead and paper Practice measuring resistance across the homemade resistor Explain series vs Parallel for resistance This is a very hands-on class offering the opportunity for students to perform the experiments themselves and gain skills with electronic tools. High emphasis is placed on safety rules. The experiments are very simple and possible for most young children to perform with minimal adult supervision. To participate hands-on, you must purchase the materials before class. This is available for purchase from the link below or you can bring your own.

학부모 가이드
Parents:
The experiments in this set of classes are fairly easy for young children, however, please gauge whether it is appropriate for an adult to be present in case the child has difficulty. Sometimes in the group setting, an individual child can feel overwhelmed with simple problems and miss out on a successful experience. I leave it to you as parent to gauge the child's capability to complete the experiments successfully.

교사 전문성 및 자격증
Electricity has been a big party of my life. As a teenager I was building computer circuits, robots, and discrete electric devices. I worked after school in my Dad's radio shack store repairing everything from radios to toasters to TV's. Through the decades I held on and developed this understanding through hands on experience as well as formal courses.
Perhaps more importantly I have a skill for explaining complex concepts in a simple easy to understand manner and a passion for plain true practical understanding to the next generation. Learning should be deep and fun!리뷰
