Electrical Tools and Symbols
This is Lesson 6 of 7 in the National FFA Organization’s Electricity Unit, a supplement to the Agricultural Technology and Mechanical Systems CDE. It introduces students to common electrical symbols and tools, teaching them to identify and draw symbols and use them to create simple circuit diagrams using the “Watt’s That Symbol?” worksheet and a video.

Common Core – Reading: Informational Text
- CCSS.ELA-Literacy.RI.9-10.1Cite strong and thorough textual evidence to support analysis of what the text says explicitly as well as inferences drawn from the text.
Common Core – Science & Technical Subjects
- CCSS.ELA-Literacy.RST.9-10.2Determine the central ideas or conclusions of a text; trace the text's explanation or depiction of a complex process, phenomenon, or concept; provide an accurate summary of the text.
- CCSS.ELA-Literacy.RST.9-10.4Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 9-10 texts and topics.
- CCSS.ELA-Literacy.RST.9-10.9Compare and contrast findings presented in a text to those from other sources (including their own experiments), noting when the findings support or contradict previous explanations or accounts.
Common Core – Speaking and Listening
- CCSS.ELA-Literacy.SL.9-10.1Initiate and participate effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grades 9-10 topics, texts, and issues, building on others' ideas and expressing their own clearly and persuasively.
- CCSS.ELA-Literacy.SL.9-10.4Present information, findings, and supporting evidence clearly, concisely, and logically such that listeners can follow the line of reasoning and the organization, development, substance, and style are appropriate to purpose, audience, and task.
