Data Analysis Reflection

Article #1:

This article illustrates the use of fake social media accounts. These specific cases are related to the political world in which these articles are used to persuade and overall bully others into following their beliefs. These accounts are used when someone wants to go unnoticed but in the undercover form of a supreme leader. They allow this individual to share their message without having their face/image attached to the consequences. Many choose to use stock photos to try and cover their tracks. What they possibly don’t realize or if they are doing it intentionally, it is simply wrong, is that these fake accounts can hurt not only the carrer of many but the rest of their lives.

Article #2:

An article as such illustrates the importance of slow news. We need to take the time as journalists to give the correct news and not the news we primarily assume. In cases like these it can mean the difference between stating that someone is dead or alive, not whether Brad Pitt and Jennifer Aniston are back together or not. I do not understand the logic behind posting a missing person image when it is entirely fake. It is a serious matter for those affected and it is not something we should be using social media to perform. Unfortunately, there are cases where these posts are intentionally fake and used to target individuals and put the spotlight on them.

Article #3:

This last article speaks about how social media can be used for (political) advertising and then deleted at the push of a button. Instead of having face to face debates we are using these different formats to share our thoughts. People can influence others without having to give reasons other than the name attached to the account. It also illustrates how people can target individuals for their skin colour, race and or religion again by the push of a button. We are able to hide behind our screens and discriminate against millions in a matter of seconds. We need to remember to use social media for good and not for reasons of hurting one another to help ourselves or our campaigns.

Math Video: The Pythagorean Theorem

Below you will find our group project for Math Honours 9, a documentary and white board style video regarding the Pythagorean Theorem. In this video there are 4 main categories: the life of Pythagoras, explaining the Pythagorean Theorem, proofs of the Pythagorean Theorem and finally real life examples in which one can use the Pythagorean Theorem. We worked really hard on this video and had a lot of fun making it. We hope you enjoy!

Everything I Know About Exponents

Prescribed Learning Outcomes for Exponents:

1) Represent repeated multiplication with exponents

2) Describe how powers represent repeated multiplications

3) Demonstrate the difference between the exponent and the base by building models of a given power, such as 3^2 and 2^3.

4) Demonstrate the difference between two given powers in which the exponent and the base are interchanged by using repeated multiplication, such as 3^2 and 2^3.

5) Evaluate powers with integral bases (excluding base 0) and whole number exponents.

6) Explain the role of parentheses in powers by evaluating a given set of powers such as (-2)^4, (-2^4) and  -2^4

7) Explain the exponent laws for multiplying and dividing powers with the same base.

8) Explain the exponent laws for raising a product and quotient to an exponent.

9) Explain the law for powers with an exponent of zero.

10) Use patterns to show that a power with an exponent of zero is equal to one.

11) Explain the law for powers with negative exponents.

12) Use patterns to explain the negative exponent law.

13) I can apply the exponent laws to powers with both integral and variable bases.

14) I can identify the error in a simplification of an expression involving powers.

15) Use the order of operations on expressions with powers.

16) Determine the sum and difference of two powers.

17) Identify the error in applying the order of operations in an incorrect solution.

18) Use powers to solve problems (measurement problems)

19) Use powers to solve problems (growth problems)

20) Applying the order of operations on expressions with powers involving negative exponents and variable bases.

….Anything else that you know about exponents.



Power: an expression made up of a base and an exponent.

Base: the number that gets multipled by itself in a power.

Exponent: however many times you multiply the base by itself in a power.

Integral base: a base that can be negative, positive or even zero.

Variable base: a base that is a letter in which it represents or can replace a number.

Exponential form: a shorter way to write a repeated multiplication.

My Digital Footprint

My digital footprint video is a way for me to share information about safe media use with my peers and teachers. Answering the questions found in the video made me reflect on the both the positives and negative uses with social media. We need to always remember to try to build a strong digital footprint, not one that will hurt us down the road. If you have any questions or compliments about this video, please feel free to leave a comment down below. Thanks for watching!
