2.11 Blown to Bits - The Digital Explosion
Today you will be reading parts of Blown to Bits Chapter 1

Part 1:

  1. Read pages 1-4 in Chapter One and Koan 4 about Moore's Law on pages 8-9 to learn more about how quickly our world has become digital. As you read, use the Double Entry Journal (File -- Make a copy for an editable version) to summarize and comment on at least four quotes or summarized ideas that the authors bring forward in this chapter. Discuss your quotes with your classmates. Read through the first four pages then create your summary or quotes. Once you have your quotes then write out your response to each quote.
  2. Watch the short video of Moore at the Intel website.
  3. Below is an image that represents Moore's Law graphically - the observation that the number of transistors per square inch on integrated circuits had doubled every two year since their invention. This means the speed at which we can process digital data increases exponentially every year. 

Part 2: Over the last 24 hours, list all the technology that you used. For example, did you use your phone to set an alarm? Make a running list of items that you used and then make a tally or count how often you used them during the day. Once you're done, consider how easy or difficult would it be to make it through a single day without using a computer. Which of your daily activities could you do without digital information or devices?

Part 3: Read pages 13-16 (Good and Ill, Promise and Peril) in Chapter One which takes a look at the positive and negative implications of the digital explosion. This is an important concept and one of the key components of the Explore Performance Task for the AP exam. Get into groups of 4 and use the Debate Team Carousel handout to discuss this concept further.
