My future with Chemistry

Lab Reflections

Final Words

I really did enjoy this course and hope future classes and students will enjoy it as much as I did to have yourself as a teacher. I believe you made the lessons much easier to grasp and understand which of course leading to the success of most likely everyone in the class. I hope next year in Chemistry may be as fun and educational as I had this year. If there were any tips that I would give to the next class you teach, it would definitely be to do the work and ask questions. Most definitely to study hard using the online resources you have given us and the mastery tests that you had put together for us. Studying and learning wasn't trouble at all but rather a breeze.

Enjoy what's left and don't forget to have fun!

The purpose of this portfolio is to demonstrate how prepared I am for the future, for when I am employed in particular I may need to work with all sorts of elements. Knowing the dangers of what some elements may do and how they react with each other is very important because having the knowledge could save myself or others from harm. Grade 11 Chemistry will better prepare me for the next level; Grade 12 Chemistry which will then prepare me for my post-secondary learning and into employment.

These labs actually mean quite a lot to me simply because I always wondered how for instance a full balloon may be getting smaller as the temperature changes. Or how heat may actually expand a container or just expand anything in general. I found learning these laws very useful to me because I may apply them later in life, understanding how molecules all around us work and react with one another.

The last unit and these last three labs had gone by very quickly and an enjoyable unit it was. I liked these labs because it deals with gas matter. Gases are of course everywhere, we inhale and exhale everyday and I enjoyed learning how it worked. I enjoy the topic and hope to learn more about it in grade 12 Chemistry and possibly research it more myself with spare time. I also liked the fact that this unit was quick and easy, it went by very fast because we did not spend classes learning the gas laws and instead just learned it very quickly at home then spent the days at school investigating the laws and doing labs. These labs of course needed much care and attention and I had learned that if I want a successful investigation/lab I of course have to have my full attention on the lab and in some way collaborate with the rest of my group to manage time more successfully. I realize that there may be just some things that I cannot do alone. I feel like these labs are developing my "Thinking Interdependently" skills. I do hope to have such a skill and have the trust to work with others in the future.

These are the three labs that we had done in class in which we had done to investigate Boyle, Charles, and Gay-Lussac's laws.

What do these laws mean to me?

The laws may not seem much but I enjoy how they relate to one another and see how they correlate. For example as Pressure goes up, volume will go down, but at the same time, if Pressure goes up, Temperature will go down. I do intend to learn more about these gas laws because I believe knowing these laws may be very important and knowing how the molecules around me react when changing any sort of variable. For example if pressure were to go up, the volume is expected to go down but also the temperature will go up at the pressure goes up. I simply enjoy how when one thing changes many other things changes, sort of like a chain reaction. Knowing these laws may just spark an idea in my head in the future and hopefully be beneficial to myself and/or my community.

Why I Chose This Topic

Chemical Trends

Did not have a picture of the dilutions lab we did, but the serial dilutions lab forced us to create a procedure and attain known concentrations/dilute the concentration from if it is too concentrated.

Dilutions lab and why it was significant

I myself enjoyed the dilutions lab because we see the process of it every single day in our lives. For example it may be coffee, it just some drinking crystals, but both go through the same process of enhancing a drink or adjusting it to our tastes. Since Serial Dilutions are widely used in all aspects of Science (Biology, Chemistry, and Physics) I believe that knowing how to do Serial Dilutions and knowing what it is is extremely important if I am looking to go into any specific field of such. I believe this illustrates my "Remaining Open to Continuous Learning" because I do believe that I will find a good use for Serial Dilutions in the future and I hope that I will learn more about the topic as I explore more into the Science fields.

Water Testing Lab

Titration lab

The chemical bonding labs and investigation of elements were a good way to access my ways to think differently and taught me how to look at the elements and how they bond. It demonstrated my "Creating, Imagining & Innovating" habit of mind. Since gaining this new found knowledge, when I bond the atoms together I'll understand why they would and wouldn't work together because I can now imagine how they are able to either share each others electrons, or if they give their electrons to one another.

Creating a Lab Procedure for the Water Lab

How/Why would this experience be important to me?

Lab Reflection/Why I chose this experience

Creating a lab procedure seemed rather hard although we all had just researched it, I wanted to understand why it is like this and to make sure it is correct. I tend to go through the procedure in my head and wonder if this works or not. Once finding the procedure for the water lab, I understood why it was like so, essentially how to get from point A to point B. I found the labs weren't just for yourself to do and discover, you have to create your own labs as well, your own experiments, thats a part of the process. To research and follow somebody else's procedure is one thing, to discover the importance of that lab, but to make one and discover your own research and discovery is a whole other task. I believe that we will be doing so a lot in grade 12 chemistry, to get to point B without help from the teacher, to figure it out on our own and discover for ourselves. The lab procedure is of course the most important part to doing your lab because you yourself must know how to do it before even trying to discover.

The Importance of my Investigation/Experience

There are many reasons as to how this experience may have been important to me. For example: I wish to persuade people such as students in the school even that the fountain/tap water is not dirty and they do not need to thirst themselves in the day or have to go and buy soda or bring bottled water all the time. The fountains are actually rather handy and convenient to have everywhere but many people overlook it because they may be unsure whether or not it is safe or unsafe to drink.

Coming up with our own procedure for this lab was not extraordinarily difficult simply because the lab was about finding an element an unknown element in the waters. To do so, just like in class where we had created a flow chart to examine which elements were contained in which water. And from there we had experiment and recorded out process.

I felt that this was one of the best and funnest experiences of the labs we have ever done because they were both interesting as to how we could either test what is in our water and doing a titration lab to determine an unknown concentration of an acid or base. I believe everyone sees water and acids or bases being used in their everyday lives and why not have some fun identifying what they may be. I believe this demonstrated my "Responding With Wonderment and Awe". This made me "wow" for finding out what sort of things were in which water. I saw it as a fun experience and definitely was a simple yet useful thing to know as I slip my way into adulthood. I enjoyed the titration lab as well because it was also just as fun finding the unknown concentration of the acid and maybe I will try to do this myself one day looking at a different acid or base. I didn't feel like it was a task at all but of course a very fun little activity with my classmates that helped passed the time in my day.

The reason this experience was so important to me was because it allowed me to physically see how the elements were bonding together and seeing how they come together as one or how they just won`t fit together for a good reason. Now knowing how the elements bond, I am able to recreate the experience of putting the elements together mentally because creating the structure is extremely easy once I can put it together in my head.

Why I Chose This Topic

My investigation on Atomic Radius, the highest point being the atom with the highest radius and lowest point being the atom with the lowest radius

I chose this particular topic because participation in the task of finding the periodic trends of elements really helped me understand each elements significant property. So when mixing these elements and looking at compounds, it expands my knowledge of thinking when conducting experiments and helps me understand why one element will be more reactive than the other and why one will react in such a way with another as well. This lesson really expressed my "Remaining Open to Continuous Learning" habit of mind.

The Importance of my Investigation/Experience

The investigation on our first look at periodic trends, when we had to plot the points of whichever trend we had chosen, for example I chose atomic radius with my partner and we found out that going left and down on the periodic table had the highest atomic radius from the atomic nucleus to the outermost orbit because it had the most shells going down and the least energy trying to pull everything together from the electrons on the outer shell. This resulted with Francium having the highest atomic radius and Helium having the lowest atomic radius. This concluded with my partner and I noticing that the Alkali Metals having the highest radius within their groups and Noble Gases having the lowest.

just lose its colour

I chose this particular part of our unit because Mr. Griffith had said it was one of most important unit of our semester. I realized after doing many calculations within other lessons that I always went back to using this chart and calculating from there. Then the sudden thought hit me; that I should always be going back to basics. This taught me that I shouldn't be making things so complicated all the time but rather taking a step backwards and breaking it down into its basics just like math. I feel that this experience allowed me to "Think Flexibly" because rather than making it so complicated and be so narrow-minded, I decided to take a different approach afterwards and go back to basics.

Lab Reflection

I decided to reflect on this lab experience of finding the quanitity of water molcules or amount of hydrates in the chemical because I found it rather interesting how our experiment went aside from everyone elses using a different chemical, rather than just the chemical like Copper (II) Sulfate turning a different colour when heated, my Iron (III) Chloride melted and the hydrate chemicals of course also evaporated. It was a rather fun and simple experiment seeing how the chemical reacted and also because I did accidently inhale a little bit of the chemical and the chlorine stinging my nose. I thought it was rather cool seeing how strong the chemical actually was myself considering how it was used in WWI I felt that I made a good amount of connections that day with the experiment that I had conducted with my partner. I feel that I took "Responsible Risks" with this lab, seeing what else I could note about the reaction.

Experience of Chemical Reactions Lab

Chemical Reactions Unit Test & Mastery Tests Reflection

This particular chemical reactions lab was the most fun in my opinion and it definitely showed me "Responding with Wonderment and Awe." Whilst learning how the chemicals reacted and learning how what type of reactions react in that way, it was clear that this particular period of experimenting how the chemicals react was fun yet a great learning experience. For example before I was never able to just look and understand how the chemicals displaced or how the chemicals reacted, but after this learning experience, I can take these examples and differentiate their reaction types!

The mark I had acquired on this test would not be as high if it wasn't for the mastery tests that I was able to use to study with. For example, I did not remember all of the functional groups right away, but once I had done the mastery test about 4 times, I was able to get 100% every time I tried it with ease. Also, studying from the mastery tests are a lot easier for me because they're online and you simply take a little bit of time to quiz yourself. To me, the results showed when comparing to my previous test; before I did not feel like I needed the mastery tests and thought I knew it all already. I believe this reflection represents my "Striving for Excellence and Precision" skills because I feel that after the disappointing mark of my first unit test, I felt the need to seek aid on my studying and the mastery tests helped me with just that.
