For Ms. Alexander's Finals she decided to do a projectile project. We had to calculate the terminal velocity of the projectile and calculate the maximum high, speed and how long the projectile would take to reach the ground. I'm really proud of this project by the different aspects of it. We had to first design, build and test the catapult while doing the calculations needed for this assignment. This assignment represented Thinking and Problem solving 21st century skill. I believe it represented this skill by showing that with the right methods and the knowledge that you can test and achieve the said goal. It also shows the skill by Ms. Alexander giving us a said rubric and no other outside help. We had to work through our problem collectively and really figure out where the issues were with either the build or the calculations behind it. I feel like I really improved on the skill by furthermore proving to myself that even after making a mistake its not the end of the world and fixing the problem can be easy as one, two, three. The most difficult part of the task was the calculation aspect of it. If you mess up one number or even one decimal the whole thing falls apart, you had to make sure you dotted your I's and crossed your T's. I could improve this work sample by making a more sturdy build. After the end of the test it was near its final launches and nearly falling apart. If I would restart the project I would add more reinforcements to the cross beams and add more tension to the kinetic mechanism. This project relates from what I've learned from the past by using my background knowledge from one of my past classes Technology/Fabrication. I could easily apply this to the future by already have a feel for objects in motion and the math behind how everything in the world works.
