Titration Lab

Communication Core competency

In my titration lab my partner and I communicated thoroughly to understand what role each of us wanted to do. We communicated to see if more water was needed and to see how much we should add. While my partner was swirling I was dropping the base in to neutralize the acid. We both contributed to the set up as well as the clean up afterwards.

Artifact

Critical Thinking

The artifact I chose was my in-class write “Mi última vacación”. I thought carefully about what I wanted to say first before translating and writing my words in spanish. I made sure to double check for grammar and spelling errors, as well as to make sure I was using the right words and tense. I looked through my notes and found inspiration for what to write and I made sure my story was cohesive and made sense. Next time I would like to challenge myself more by expanding my vocabulary.

Transforming Parabolas

  1. The red parabola with the vertex at (0,0) represents the parent function f(x)=x², which has not been transformed yet.
  2. The thin black parabola demonstrates a vertical shift up using a positive k value, y=2(x+4)²+4, and stands for the y value in the vertex (-4,4).
  3. The blue parabola demonstrates a vertical shift downwards using a negative k value, y=1/3(x-6)²-2, and stands for the y value in the vertex (6,-2).
  4. The green parabola demonstrates a horizontal shift to the left, making the h value positive in y=2(x+2)²+2, and it also stands for the x value in the vertex (-2,2).
  5. The yellow parabola demonstrates a horizontal shift to the right making the h value negative in y=(x-6)²+2, it also stands for the x value in the vertex (6,2).
  6. The purple parabola demonstrates a vertical stretch since the value of a in y=9(x+7)²+2 is greater than one making it taller and thinner, and since it is positive it opens upwards.
  7. The thick black parabola demonstrates a vertical compression since the a value in y=1/4(x+9)²+5 is less than one making it shorter and wider.

Equations used

  1. f(x)=x²
  2. y=2(x+4)²+4
  3. y=1/3(x-6)²-2
  4. y=2(x+2)²+2
  5. y=(x-6)²+2
  6. y=9(x+7)²+2
  7. y=1/4(x+9)²+5

Communication Core Competency Reflection

I can understand and share information in a clear, organized way. I am able to prove my ability to understand parabolas and each value involved by completing my assignment and talking about how each of the values affects the parabola. I paid attention during my lessons and took in all the information necessary to be able to comprehend the subject. I also looked over my work multiple times to make sure I was clear and understanding for anyone else who wants to understand parabolas.

I think about what I am going to convey and to whom I will convey it. In this project I took time to make sure I understood what I was writing and doing, as well as making sure my parabolas followed each rule provided for me, so it is important that my writing is understandable for my peers and teachers who want to follow along. I ensured that the explanation in my project consisted of correct spelling, relevant mathematical vocabulary, and appropriate punctuation.
