 * = **Digital Information** ||
 * **Unit EQ: How do computers make students or employees more productive** ||
 * **LEQ: Is the transistor the greatest invention in the last 50 years?** ||
 * **Activating Strategies:** take out paper and [|list things that have transistors in them]?(link to video) ||
 * **Acceleration/Previewing/Vocabulary:** Write a sentence using the following words: Digital, Binary, Analog, Information. Call on 2 students. ||
 * **Teaching Strategies and Distributed Guided Practice/Summarizing Prompts:**
 * 1) Check Math Lab Homework [[file:Math calc lab.doc]]


 * __Digital Information__**

Digitial vs Analog * Analog, varying voltages, [|volumes], rotations
 * Analog - uses dials for output - [|clock with hands], [|speedometer]
 * Digital - Digit means #.
 * Divided up into specific increments and assigned #s -
 * Digital [|clock]digital [|speedometer]

Microprocessors: Transistor is a switch without moving parts. > Digital Information [|Moodle Quiz #2] ||
 * [|Fetch, Decode, Execute] Mention how math lab shows how slow we are!
 * Transistors are made from silicon. Silicon is a semiconductor. A material whose conductivity can change.
 * Scale of Transistors : How big is a [|human hair?] About 100 microns in diameter. That means a[| transistor]is just 0.045 microns wide. [|Transistor Timeline]
 * [|Binary Code]
 * Bits zeros and ones
 * show CAT binary overhead slide
 * [|Pixels](video)
 * Dots in a digital image.
 * Show rollerblade overhead ||
