The Small Bridge vs The 10 Pound Goliath


 Hey Visitor, in this class called Urban Planning we talked about the physics and math behind building a bridge. The history of architectural artifacts in history, where compression & tension exists in the bridge, why we need to know these things; and the math formulas required like law of sines, cosines, Potential  and Kinetic energy. After learning this we were asked to create a bridge that was able to support 10 Ibs while only building the bridge with glue sticks and 75 popsicle sticks. 

We didn't have a draft of the original building because we knew our idea will progress further and improve but the one that we ended up using is this.

     My partner and I had numerous conversations about the type of triangles we would use for our bridge. We believed that choosing the right triangles was crucial because they needed to support the weight effectively. The main challenge we faced initially was figuring out how to make the bridge stand. We decided to start by building a foundation and then adding popsicle sticks horizontally to it, so we could later incorporate the triangles. We opted for equilateral triangles for the sides because they are commonly used in bridge construction. We wanted to take a safer approach rather than attempting to create a completely unique bridge design.

After everyone tested their bridges, our class discussed how this project relates to SDG 11. One key point that stood out from the conversation was that bridges help connect communities. The creative process involved in bridge construction, where we had to consider resource limitations and safety precautions to bear the weight, mirrors the precautions architects take when designing structures for city plans.

As for our bridge, it did bend, but it successfully held the 10-pound weight for more than 10 seconds. I consider it a success, even though the bridge may not be the most visually appealing. I am delighted that it was able to support the weight, especially since this is the FIRST TIME I have had a project in this class that actually WORKED! Hopefully, my future projects will continue to be successful.

The Gulf War

 Hey Visitor, In this class called Policy, we looked at the 3 branches of government, the history of law-making, how law is interpreted, and what follows up to an act or a law. In this Unit of Policy we focused on the Judicial and Executive branch. In class we split up the Constitution to look over the 1st and 2nd article to dissect it to figure out what the President can and CANNOT do. Like how the President's appointed officials have to be interviewed and granted the position by Congress. How Congress rules over inferior courts, and etc. All of this was used to build our understanding if war can be justifiable. With our Field Experience to the Everett M. Dirksen courthouse we took a tour and analyzed how cases in court are processed,  how evidence is presented, then we had lunch with attorneys and a judge. Now proceeding to the project we were asked to identify a war and to see if we personally though that the war was justifiable with evidence and make an essay on it. I accidenta

K's Kitchen

  Hello Visitor, In Spanish we learned about ingredients, fruits, commands, and utensils that are commonly used in the kitchen; and learned how to form past participles. In this action project we were asked to create a menu consisting of breakfast, lunch, and dinner. My menu will be This is my video.  I would say the hardest part of the project was editing as my editing software was crashing as I was trying to put in audio clips making it more difficult under the time constraint I was under. I should've separated the editing process to 3 days so I can focus on Captions, Video clips, and Audio independently instead of altogether making the process more convoluted.

Unit 3 Action Project

Hi Visitor! This project was for the class called “Urban Planning” . This is our 3rd and final unit of the class and during this time we learned about Ancient cities and structures, City planning ideas, current problems in cities and solutions or hypothetical solutions, and how cities evolved differently like New York and Amsterdam. In this Project we were asked to pick an area that we wanted to improve and make at least 5 improvements to the selected area. The general area I chose was South Shore due to my previous knowledge of knowing that South Shore was disinvested in; and the specific address I chose was 2507 E 79th St since it has no current use and it has a lot of potential to be repurposed so I went with it.      The main purpose I had for this area was to create a community farm because according to data in 2019; 57% of residents in the South Shore area live in a food desert. So I thought this would be very beneficial for the South Shore neighborhood since this would provide
