    • File Size Video- (4min)
  • Video- Text compression widget with Aloe Blacc
  • Lesson 9- Students use the Text Compression Widget to experiment with compressing songs and poems and try to find their ‘personal best’ compression. A video introduces important vocabulary for the lesson and demonstrates the full features of the widget. Students pick a text they think will be ‘easy’ to compress and one they think will be ‘difficult’, paying attention to why some texts might be more compressible than others. As a wrap-up, students discuss what factors make some texts more compressible than others.
  • Lesson 10- Students are introduced to lossy compression via the Lossy Text Compression widget. They apply this concept and their prior knowledge of sampling to create their own lossy compressions of image files using the Lossy Image Widget. Students then discuss several practical scenarios where they need to decide whether to use a lossy or lossless compression algorithm. The lesson ends with a discussion of the situations where lossless compression is important and the situations where lossy compression is important.
  • Using abbreviations and symbols is a form of compression, where we try to represent the same information with fewer characters.
  • Use the Text Compression Widget to experiment with compressing songs and poems and try to find your ‘personal best’ compression.
  • The widget we are using is an example of lossless compression
  • The compression percentage at the bottom of the screen is calculated by comparing the number of bytes in the original message and the number of bytes in the compressed message.

  1. Take This Binary Quiz (5pts)- You may use your notebook/journal.
  2. Website- Computer Counting Number Converter
  3. Websites- Binary Converting Video Game- Challenge Someone / Binary Game 2

Errors-

  1. New Vocab Term - Overflow Error- An error that occurs when the computer attempts to handle a number that is too large for it. Every computer has a well-defined range of values that it can represent. If during execution of a program it arrives at a number outside this range, it will experience an overflow error.
  2. Watch Video (8min)- How Gangnam Style Broke YouTube
  3. Read Article- The Y2K "Apocalypse"

    • Can't Create all fractions (Not Enough Bits)
    • We cna represnt some depending on how many bits we have
    • Video- Convert 3/4 to binary
  5. Quiz Wednesday on Gagnam Video, Y2K Article, and Binary Fractions (5pts)

 

New Topic- Letters and Keyboard Buttons expressed in Binary

  1. My PowerPoint For Text and Binary
  2. Vocab Term- Protocol- Rules and regulations we all agree to use
  3. We know how computers count using binary now, but what about text, words, sentaces?
  4. Representing Text in Binary
    • ASCII (American Standard Code for Information Interchange) is one of the most common character encoding standards.
    • Originally developed from telegraphic codes, ASCII is now widely used in electronic communication for conveying text. As computers can only understand numbers, the ASCII code represents text (characters) with different numbers.
    • This is how a computer ‘understands’ and shows text.
    • The original ASCII is based on 128 characters. These are the 26 letters of the English alphabet (both in lower and upper cases); numbers from 0 to 9; and various punctuation marks. In the ASCII code, each of these characters are assigned a decimal number from 0 to 127. For example, the ASCII representation of upper case A is 65 and the lower case a is 97.
  5. Watch video (8min)- ASCII (Binary as Text)
  6. ASCII Chart- Sample ASCII Chart
  7. Let's try it...
    • What does this say- 01010101 01010011 01000011
    • Can you write your first name in Binary???
    • My name (Casey) is in the graphic to the right -->
    • Write in Binary- "Hello, I am ____. I am ____ years old."
    • There are online converters (like this one) if you want to wimp out and cheat
  8. Sending text messages is really sending binary numbers. It all comes back to zeroes and ones, always! Binary is KING!!!
  9. Use your code.org Log-In code
  10. Complete Code.org Unit 1 Lessons 4-6 (6pts)- Due by start of Class on Wednesday
  11. Syllabus- Wednesday

  • Code.org Discussion
  • Every Class- Ctrl, Shift, R
  • Make-Up Quizzes- Any Brunch
  • Quiz- 5pts
  • Vocab- Analog, digital, metadata, pixel, and sample
  • Students explore how black and white images are represented. Students use the black and white pixelation widget on code.org to represent each pixel of an image with black or white light. They learn how to sample an analog image using small squares of uniform size (each represented with a black or white value) and reflect on the pros and cons of choosing a smaller or larger square size when sampling.
    • Pixel- Picture Element, smallest square on a screen
    • Pixel- White or Black pixel for today
    • 0 = Black (Light Off), 1=White (Light On)
  • Watch Video- Screen Histury (2min)
  • Analog Data - Data with values that change continuously, or smoothly, over time. Some examples of analog data include music, colors of a painting, or position of a sprinter during a race.
  • Digital Data - Data that changes discretely through a finite set of possible values
  • Sampling - A process for creating a digital representation of analog data by measuring the analog data at regular intervals called samples.
  • Metadata- Information about data/files
  • Watch Video on your monitor, turn on CC- B&W Pixelation Tutorial (3min)
  • Solo or With Friends, Complete Code.org Unit 1 Leeson 7 (2pts) Including Challenge A, B, & C

Day 2- Thursday August 13- Binary is King!

----------

Binary Numbers-

In this lesson, students will practice representing numbers in binary (base 2). Students can convert between binary (base 2) and decimal (base 10) numbers. They will practice converting numbers and explore the concept of place value in the context of binary numbers.

  • Counting Systems
  • Base 10
    • We are amazing at counting in Base 10
    • 10 Digits on our hands?!?!?
  • Base 2. Why binary?
    • Transistor- Electric current or voltage
    • Digital- 0 or 1, A or B, Yes or No, On or Off, etc...
  • CPU- Central Processing Unit
    • Made of Transistors (No Electricity = 0, Electricity = 1)
    • iPhone 16 Pro has 20 Billion Transistors in it's CPU
    • Silicon- Conducts Electricity
  • CPU Clock Speed
    • Frequency of Checking the Transistors
    • IPhone 16 Pro 4 GHZ (4 Billion Times per Sec)
  • Moore's Law-
    • The observation that the number of transistors doubles approximately every two years. This has historically led to exponential increases in computing power and a decrease in the cost of computing. While originally a prediction of a trend, it has become a guiding principle for the CPU industry and a driver of technological advancement.
  • Let's act like CPUs and count in binary
  • Website- Computer Counting Number Converter
  • Website- Binary Converting Video Game- Challenge Someone
  • Bit and Byte
  • Binary Quiz Monday next week!
