Grade 11

Titration Lab

Curricular Competency Reflection

The slow addition of a solution with a known concentration (sodium hydroxide) to a solution with an unknown concentration (hydrochloric acid), was used to calculate the molarity of hydrochloric acid. The end point in a titration is when the reaction is complete. As an indicator was used, the finish line of the titration was when the solution stayed a pale pink for at least 30 seconds. Within both trials an average of 14.14 mL +/- 0.20mL was used in the titration.

Core Competency Reflection

During this lab I actively supported and encouraged my peers. I created a collaborative and upbringing environment. By thinking back to in class lessons and activities I applied that knowledge in the lab to connect the strategies upon accuracy with my partner. By emphasizing respect and inclusivity I allowed my partner to speak their voice and thoughts creating a sense of belonging. Moving forward I plan to enhance my collaboration skills and involve all team members diverse thoughts and opinions.

Initial volume 0.11mL +/- 0.05mL (trial 1)

Initial Volume 0.00mL +/- 0.05mL (trial 2)

Final Volume 14.03mL +/- 0.05 mL (trial 1, trial 2 was not taken picture of)

Transforming Parabolas

Equations

Parent Function: y=x² My Function: y= 4(x+1)²-2

Graphing

My quadratic equation, y = 4(x + 1)² – 2, introduced multiple transformations to the parent function. It brought about both vertical and horizontal shifts, as well as alterations in the parabola’s shape. With a positive h-value of 1, the parabola shifted to the left of the x-axis, moving the vertex one unit to the left. Simultaneously, the negative k-value of -2 shifted the vertex downward by two units along the y-axis, resulting in a final vertex of (-1, -2). Moreover, the a-value exceeding 1 led to a narrower parabola.

Self Assessment

  1. In this assignment I used a verbal description and a visual graph. In a written paragraph showing my understanding of parabolas and transformations I connected it to math terms we’ve learned in class as well as the visual graph I created.
  2. In my paragraph I used the words quadratic equation, vertical/horizontal shift, vertex, to explain my understaffing of transformations.
  3. By using bolded text on each topic within the assignment I talked about, it is evident to see when a new topic starts. When creating my graph in demos I made sure there was no overlapping or messiness to it. Everything is clear and easily readable.

Where the Blood Mixes Assignment

Where the Blood Mixes Literary Paragraph 

There are many examples within the literature that illustrate the character of Mooch. It is evident from the story that mooch is a complex induvial. To start Mooch is an untrustworthy man. He shows his unreliable nature when he “continues to steal June’s money.” Even after June pours her heart out to Mooch in confidence that he will stop lying to her, he continues to take money from her. Additionally, Mooch is emotionally unstable. He suffers from PTSD after “attending residential school as a child.” He was sexually, physically, and emotionally abused. He shows his unstable attitudes by always drinking away his problems. His friends are always there for him as they continue to pay for his drinks and always go easy on him. And finally, Mooch is a “sensitive individual.” He does this by always being there for the people he loves. For example, he took Christine from Anna when Anna committed suicide. As well as when Floyd was going through the reunion with his daughter. To conclude, it is evident Mooch has both positive and negative attributes to his character. 

Facing a Challenge

The first time I tried this problem I found it challenging because I was confused as to what to do with the x squared. The first mistake I made was trying to put both sides of the equation back into the radical. There was a question just like it in group work, however it wasn’t my turn with the pen and I was just watching and observing. When I got to this workbook question I realized this was like a group work question and went back and remembered the strategy my group members came up with. I used the zero product property rule all the way back in 1.2, and factoring. I really enjoyed solving this problem because it showed how important factoring is, and how we can apply it into more complex problems. Next time I encounter a problem I will look through the notes and examples more.I try and use the examples almost as if they were a formula that I can “cut and paste” into any problem.
