Chemistry 11 Titrations

What is a titration? A titration in a chemistry experiment requires the use of a burette with a solution being poured into another solution with a known volume until the reaction is just complete. You can simplify this by saying its just like mixing two things until you reach the right spot. We used titration in our lab when we mixed an average of 14.23mL of NaOH into our Erlenmeyer flask that contained 10.0mL of HCl. Before mixing 3 drops of phenolphthalein was added to see the titration. The endpoint of a titration is when the reaction is complete and both solutions are mixed perfectly, we knew when we reached the endpoint of our titration when the pink color that we would see when mixing the liquids was taking longer to vanish, then when it would take 30s of the color being very light pinkish before vanishing. Our finished results was the titration taking an average of 14.23mL of NaOH to complete.

Collaborating Reflection

I can take on roles and responsibilities in a group; I do my share.

I was in a duo group during this lab experiment but was left to be solo after my group member got sick, he did some of the dirty work and he’s usually the one that does better on the physical lab part while I do most of the sheets. I was forced to relearn it by myself and take on both roles. I ended up doing all of my trials and getting the numbers we were expected to get. I also ended up completing the lab, and helping my sick group member complete it after I finished both the lab and the handout.

My Parabola

My Parent Function and Equation

Significance of “A”, “H”, and “K” In My Equation

The significance of “A” in my equation determined both the way the parabola would face, and how thin or wide it was. The higher the number, the skinnier my parabola would end up being. If my number was “-5” instead of “-2”, it would still face downwards but the parabola would be a lot skinnier. If the “A” value was just “5” it would now shift upwards and be skinnier then “-2” because the “A” value is positive and a higher number. The significance of “H” in my equation would represent the X value my parabola sits at, just opposite. In my equation my “H” value is “-6”, but because its opposite so the X value that it sits at would just be “6”. If I switched the “-6” to a “-2” it would switch to the X value of “2” on my graph. The “K” value is very similar as it moves the parabola up and down instead of side to side. Except for my “K” value, it is what it looks like. As my “K” value is “+1”, my parabola sits at the Y value of 1. If I were to swap my K value from “+1” to “-2” it would switch down to the -2 Y value. It is also important to mention that both my “H” and “K” value came from my vertex which would be, (6,1).

Self Assessment

I represented the same mathematical idea in multiple ways by giving examples on what would happen If I changed the values I was given. I also showed how they represent each aspect on the formation of my graph.

Some of the relevant mathematical words I used would be “Parabola”, this is the actual shape of my graphed equation. A few more would be my values, “a”, “h”, “k”, “x”, and “y”. these all represented specific changes in my equation and also points or movements of my Parabola. At the end I also explained my “vortex” and how it plays and important part plugging in numbers into the equation.

I used the website “desmos.com” to format my graph and show it in the most clear and understanding way as possible. I also showed the equation I used for the graph and explained the important and recognizable details of the equation. I also kept this Edublog sectioned and titled to separate the information and keep it clean.

Facing a Challenge

These types of questions were very new to me as I haven’t worked on radicals for over 6 months and I am in general just a slow learner when it comes to math. It took a little bit of thinking to make way through parts of the questions until I eventually learned it with help.

My main mistake was everything to do with restrictions. Restrictions is a whole entirely new topic for me and as I mentioned earlier, it takes me a lot more time to learn these new solving methods, and restrictions were no exception as they confused me quite a lot.

After all my struggles I asked one of my group members who knew how to do these questions and were clearly good at it, how to do restrictions and if my current answers were good. They gave me tips and helped me understand radicals more as well and showing me restrictions.

I need to remember how to plug in numbers and equations in all the ways you can, as well as finding restrictions and simplifying radicals to the best of my ability. A bunch of other smaller things that also go into this but I basically have the majority of them covered

Next time I encounter a difficult problem I would ask one of my group members, one of my smart friends in another class, or watch a few videos online.

Math Self Assessment

How do you prepare for a test? Does this seem to work for you? Are there changes you need to make to ensure your are successful?

I’m not a good at remembering or in general math so I take extra measures for each math test. I usually get peer tutored by a friend to ensure I understand the work, or I get my work checked and corrected / taught by my brother who is attending grade 12 physics currently. For math tests, I usually get a few hours of peer tutoring the day before or 2 days prior to the test, as well as multiple hours studying at home. Recently I believe I have been missing some things to study that are testable which is effecting my mark. I am studying a lot I just believe I need to spread out that study time and ensure I understand everything rather then mastering the more important parts.

What is your strength in group work? How do you use this to actively contribute during group work activities?

My strength in group work is overall just working together, understanding ideas, and expressing my methods and thinking. I use these skills to showcase my work in an orderly format while expressing the ways I do the given questions. I also learn best when I am grouped up with friends that I can communicate with and ask as many questions as I can.

CPR Reflection

My Learning of CPR

  1. What was something you learned that you didn’t know or consider before?  

I didn’t know the steps and important key factors to preforming CPR. I didn’t know the 30 chest compressions rule, the safety processions and form.

  1. What is a key takeaway from the Theory or Practical CPR unit? 

the hand over wrist form, and knowing how to to the EAD + knowing how to assess hazards.

  1. How does this unit connect to the nutrition unit learned previously?  

Because having a bad nutrition can lead to attacks that require CPR and sometimes an AED to revive the patient.

Core Competency Reflection

I can describe how learning about CPR relates to my life
My family has a history of heart attacks and strokes, I may need to use it incase something like that happens. My mom also has high blood pressure.

One of the ways I can see using this learning to help others is… 
If someone ever asks me how to preform CPR I can confidently tell them the steps and the rules I learned

One area of CPR in which I’d like to spend more time learning is… 
I would like to learn more terms, also have perfect form and confidence.

Core Competency Self Assessment

Out of the many topics we learned in class, I studied and tried most during the World War 1 unit. Out of the World War 1 unit I learned most about trenches and trench warfare. I learned new studying methods and I was proud of how interested I was in the World War 1 unit and the test. I studied long, hard and got a mark I’m proud of. I would like to get back in the working mood after being sick for a while. Grades is an important thing I am focusing on this semester.

Career life Education Core Competency Reflection

How would you describe your personal identity? How is it similar or different than that of people around you?

Everyone’s personal identity is completely unique. Millions of people may share the same personality type, but no one is the same. I would say my personal identity changes all the time based off confidence, grades, and stress level. Other peoples personal identities may change or may not based off of things happening in their life. They can control how things in their life effects their personality type. Some people may not be able to change how they act. Bad things could be happening at home and people just snap or can’t control it in that state of mind.

I can identify my strengths and limits, find internal motivation, and act on opportunities for self-growth. I take responsibility for making ethical decisions.

Identifying your rights, wrongs, and what to do next time is important for self growth. Thinking before doing something that could have a giant impact on your life. Thinking to yourself “Is it a good idea to jump in this low tide risky water”? Is a reasonable thought. Know your worth, don’t let people take advantage of you and be the best person you can. People will respect you more if you take your time to make good decisions as well as being yourself and the best version of yourself.

Core Competency Goals

  1. Some of the ways I work to build and maintain relationships are…

Commonly communicating, checking up on people, and being hanging out when friends.

  1. What contribution have you made to our school or community that you feel good about? How did you get started doing that?

I have picked up trash, put my trash in the correct bins, and I did not litter.

  1. How have you improved this year in…?

Confidence, more dedication to school / grades, engaged with more people.
