Catapult Project

In this project, me and my partner worked very well. We frequently discussed design ideas and proposals for new improvements to give us a farther distance. We’d also frequently test out our catapult and talk about any issues we notived. I was valuable to my team as i did ssveral important calculations involving the accurate placement kf several catapult components, using frig to find the max distance we could move our catapult forward on the cardboard base and determining the minimum required distance for a 100%. My partner was valuable as they were skilled eith their hands, being able carry out the construction of the catapult carefully and efficiently. In this project, i learned that everyone has their strengths and weaknesses and in a project, to produce the best result, the group members should work on parts that they are most familiar with, whether it be doing the art on a poster board or writing content for a tri fold presentation.

Titration is a technique used to find the concentration of different substances. It involves reacting a solution of a known molarity with a solution that has an unknown molarity. In acid-base titrations, an indicator such as phenolphthalein is used to determine when the titration has reached its equivalence point, a point in which the moles of acid are equal to the moles of base. You know you’ve reached the endpoint of a titration when the indicator substance is the lightest shade of it’s indicating color. In the case of phenolphthalein, its when the substance has turned a very light shade of pink. In this lab, titration was used to find the molarity of hydrochloric acid when mixing hydrochloric acid with sodium hydroxide. In our experiment, we came to a concentration of 0.02046 (0.02 with significant figures applied) molar.

Core Competency: Communication

I can work with others to achieve a goal. This was seen in our experiment as me and my partner frequently communicated with one another to ensure we have all the correct materials and the correct quantities of each solution. During the titration procedure, we also frequently relayed the volume of the burette to each other as well as how long it took for the pink color in the phenolphthalein to dissipate. This allowed us to get a better understanding of how close we were to the equivalence point.

A number of different events occurred on the same day as my birthday. Some of these include:

1. In 1945, the Red Army (The Soviet Army) penetrated 25 miles through the German lines in Southern Poland.
2. In 1990, In Virginia, Douglas Wilder was elected as the first African American governor of a US state.
3. In 1931, The bridge connecting New York and New Jersey was named the George Washington Memorial Bridge.

My favorite website is YouTube.com. I chose this site because it has a wide range of different videos for almost anything. For example: if I’m struggling with a homework concept, I could watch a video to help me understand it, if I want to listen to music, there’s a vast amount of YouTube channels for each genre to suit my interests. In conclusion I greatly enjoy going on YouTube and the amount of content on the site grows more and more each day. http://www.youtube.com

This is House of Stairs, a lithograph by M.C Escher. I chose this picture because I find it fascinating. When I see this picture, I wonder where all the stairs lead to and if they’re all somehow connected. I also really enjoy this picture because it reminds me of my grandfather who sketched similar works of art like this one. I originally found this lithograph in an M.C. Escher artbook/biography that was given to me by my grandfather, but I got the image from Wikiart.org

I find this video very interesting and meaningful. It follows the story of a man who dies in a car crash and meets God in the afterlife. They talk about the meaning of life and the man soon discovers that he represents all of humanity, as God’s child. This video makes me think about whether or not my life and what I do during it will really make a difference and if humanity will ever mature and grow fully as God intended.
