Computer Science & Digital Literacy


Week 18: Jun 1 - Jun 5

Last Meeting: Thu Jun 4 at 1:00pm
- be sure you are checking that you have at least an 80 or above for T4
- there are no new assignments coming so get caught up if you need to

Week 17: May 26 - May 30

Meeting: Thu May 28 - 11:00 AM

- leading lines - where the viewer of your photos attention is drawn to lines that lead to the main subject of the image. A leading line paves an easy path for the eye to follow through different elements of a photo

Here is my own photo that I took at the top of the tower in Provinetown - it is a view of the staircase from the top - I guess it could also be considered a Point of View photo along with Leading Lines

Week 16: May 18 - May 22

CSDL - Thu May 21 @ 3:00 pm


Week 15: May 11 - May 15

CSDL - Thu May 14 @ 3:00 pm -


- Internet of Things (IoT) - computing devices that can transmit data over a network without needed a human interaction. It can collect data, transmit data, and analyze data in order to take action - for example, a "thing" could be a person with a heart monitor implant, a farm animal with a biochip transponder, or an automobile that has built-in sensors to alert the driver when tire pressure is low
- point of view -
refers to the position the camera is in when viewing a scene. Are you laying on the ground, looking up at your subject? ... subjects can be dramatically distorted simply by where you place your camera
- rule of thirds
- in photography, the rule of thirds is a type of composition in which an image is divided evenly into thirds, both horizontally and vertically, and the subject of the image is placed at the intersection of those dividing lines, or along one of the lines itself

  • View: Rule of Thirds
  • Complete: Rule of Thirds Photo Assignment

  • View: What is IoT - Future of Tech
  • View: The Dangers of IoT
    - while this is a company ad the examples at the end are real
  • Complete: IoT Assignment
    - Look for a news article about an IoT device that has a benefit
    - Look for another news article about an IoT device that has been hacked
    - write a short summary of the articles, what the pro/con was, and your thoughts on these devices


Week 14: May 4 - May 8

Thu May 7 3:30pm

    Vocabulary: Week 14
    - Big Data - a broad term for datasets so large or complex that traditional data processing applications are inadequate
    -Moore's Law - a predication made by Gordon Moore in 1965 that computing power will
    double every 1.5-2 years, it has remained more or less true ever since

  • Complete: Google Trends Activity
    - you can create a Google Doc to answer the questions
    * be sure to put that in the CS folder!
    ** challenge:
    - for the search terms use: purple, red, green
    - then change the date range to the last five years
    - look at April 2016 and you will see a bump in the purple search

    - can you find out what caused it?



Week 13: Apr 27 - May 1


Week 12: Apr 20 - Apr 24

CSDL - Thu Apr 23 1:00-1:30pm

*** Be sure when you create a new folder or document for this class that you are in the Google Folder already - some of you are sharing docs with me but you don't need to do that if your work is already in the folder...


Week 11: Apr 13 - Apr 17

Week 10: Apr 6 - Apr 10


Week 9: March 30 - April 3

- CSDL Thu Apr 2 - 3:00 to 3:30 pm

Grades are moving to a pass/fail with a pass meaning you have participated and completed at least 80% of the assignments..... If you look in Powerschool you will see checkmarks, incomplete, and missing for assignments. You might want to be sure yours are all green checkmarks as that is what will be the deciding factor in passing the class. Questions? Just ask me via email or attend a Google Meeting.

Week 8: March 23 - March 27


Week 7: Mar 16 - Mar 20


Week 6: Mar 9 - Mar 13


- bit - smallest unit of digital data - can only be a 1 or a 0
- binary - a number system that only uses two numbers (0 and 1) - computers operate in binary (this is how information is processed and stored)
- byte - a collection of 8 bits - data storage is measured in Bytes - generally an uppercase B indicates Bytes
-- KB (kilo) = approximately 1,000 bytes (thousands)
-- MB (mega) = approximately 1,000,000 bytes (millions)
-- GB (giga) = approximately 1,000,000,000 bytes (billions)
-- TB (tera) - approximately 1,000,000,000,000 bytes (trillions)

hexadecimal number system - sixteen-digit number system where each number represents a power of 16
0 through 9, then letters (A = 10 up to F = 15)


Week 5: Mar 2 - Mar 6

Week 4: Feb 24 - Feb 28


  • animation - a series of images that create the illusion of motion by being shown rapidly one after the other
  • frame - a single image within an animation
  • frame rate - the rate at which frames in an animation are shown, typically measured in frames per second
  • property - Attributes that describe an object's characteristics
  • sprite - A graphic character on the screen with properties that describe its location, movement, and look.


Week 3: Winter Break

Week 2: Feb 10 - Feb 14


variable - A placeholder for a piece of information that can change.

parameter - An extra piece of information passed to a function to customize it for a specific need

randomNumber() - chooses a random number between a minimum and maximum value. 

domain name system (DNS): maps internet domain names to the internet protocol network addresses they represent and allows websites to use names, rather than difficult-to-remember IP addresses

Internet Protocol (IP) - the way devices communicate with each other

packets - Small chunks of information that have been carefully formed from larger chunks of information.

router (as part of the larger internet): a computer which receives messages travelling across a network and redirects them towards their intended destinations based on the addressing information included with the message.

tcp/ip protocol: TCP (transmission control protocol) takes care of the message by breaking it up into packets (what is going) while the IP (Internet Protocol) takes care of the addresses (where it is going)

to / from address: Like an IP address, included on every message sent over the Internet


Week 1: Feb 3 - Feb 7
