When i first got into this course i was excited to see my professor, how the class would be structured, and some of my peers and classmates. My initial reaction to this course was thinking it was a pretty intresting and fun class. I've never hated science in my life but i won't sit here and say its been my favorite class since i was little, with that being said i didnt want to make any assumptions on how this class would go for me so i just kept showing up to class and before you knew it i was learning and having fun in the process. My expirences in this course has been a great expirience, i say that because as a busy college student with little time to spear, i really appretiated my professor for not implemting home work as a part of the class, instead i am greatful that he pushed each and every last one of his students to work efficently and get everything done in class. I enjoyed this method of teaching and because of it i feel like i have learned quite a bit. The activites were never boring, they were fun activites that truly helped u learn about all sorts of things that has to do with physical science. I expected this to be just a regular boring science class but it was much more then that. I thank our proffesor for that. Lastly i feel like completeing the activites opened a new perspective when i think about science, now when i think about it i will think about it in a positive mind frame. I learned alot but what i truly enjoyed is that the information we were learning is very good and helpful information to know, and i appreciate that. It changed me as a [erson because now when i think of science instead of thinking "boring" ill be excited to learn something. In conclusion i feel like this was a great class and i definitley recommed this course to anyone, i gaurantee you will enjoy ur expierence.

Learning about this topic is very interesting and necessary. As someone who goes to the gym alot, youll often see me wearing my headphones listening to some loud music, so loud infact that on my health app it stated that my exposure to noise has been over capacity for a while. Further more i was very intrigued on what i could learn and boy did i learn a bunch. I did not know i can hurt my ears with street noise! Even less did i ever think i could hurt my ears by simply just eating my food in a chipotle. Moving on i will be taking the tips from the video and try to control the volume i am hearing things more often. Things like just putting the volume less on my music, moving away from loud areas to areas that are more quiet. Things like the app shown in the video that reads how loud something is can be pretty useful as well.

Hey everyone, as we all know the ocean is huge! The ocean covers over 70% of the surface of our planet. Altough With all this being true there are still certain places and people around the world that don't get their necessary amount of fresh water daily. These are usually the dryer places around the world. Think about a dessert. I think desalination of ocean water would be a great solution to provide fresh water to dry areas of the world becuase theres so much water out in the ocean that no negative effects will be the cause of using ocean water. There are two main techniques, you can boil the water, then catch the steam, leaving behind the salt. Or you can blast the water through filters that catch the salt but let the liquid through. This would create so much more available drinking water, I think its a step in the right direction and we should start as soon as possible.

Why did i select the topic i selected UNSG#2? I selected this topic of hunger because as humans i feel like the bare minnum for us is to have acess to food.  Extreme weather is a driver of world hunger. As global temperatures and sea levels rise, the result is more heat waves, droughts, floods, cyclones and wildfires. Those conditions make it difficult for farmers to grow food and for the hungry to get i will it be impacted by climate change?

About 200 million years ago, all the continents on Earth were actually one huge "supercontinent" surrounded by one enormous ocean. This gigantic continent, called Pangaea , slowly broke apart and spread out to form the continents we know today.

What caught my attention is how it listed the potential threat to our lives here on earth. It stemmed from issues like global warming, all the way to AI that can surpass human intelligence and take over, i learned a lot of good stuff.

What caught my attention in the video is the idea that bacteria and fungai have evolved to produce powerful enzymes that break down  materials into digestable nutrients. While this is true, they cant break down plastic! Breaking plastic takes up alot of heat that is deadly to most microbes, this means that plastic doesnt degarde, so it just piles up. Most of it ends up in the ocean and its really polluting our waters.

Week 2: Discussion Climate gentrification

# data[].attributes.body
Watching this great imformative video, opened my eyes to the reality of whats going on in miami. I didn't know there was a such thing as climate genterification going on, i only ever heard of the normal gentrification. The fact that homestead is 2 to 3 feet above sea level compared to little hatii being 6-8 feet above sea level caught my attention. Another fact that caught my attention is that 22 percent of public housing in little hati is owned by a company, in comparison to the rest of miami which is just 6 percent. Thats 3 times as much. What spoke to me were the nice people in the video from their communitys that are suceptible to weather gentrification saying they have a beautiful community. I think its wrong to push these residents away from their homes in order to rebuild or destroy their house to give to other people of higher class that make more money, that is very wrong. we're pushing the people that made this city what it is, the locals away which is really wrong.

After watching Adan Palerno's, story of sunest park here are my takeaways. Just like miami some parts of new york seems to be getting affected by gentrification. Its sad to see how in the begening of the video it showed the hispanic familys dancing having fun outside of their houses and then it shows how gentrification took that all away. It then goes into showing some parts of the narators life growing up, seeing his mom fight with the landlord, even taking him to court for some shady buisness, he saw his mom not give up and he wanted to do the same. He started helping his communites by painting the roofs of the buildings in his neighborhood to the color white to keep it cool, he also planted gardens on the roof so his community could become for sustainable. Lastly he went around mechanic shops to spread information on how to properly deal with waste and other important things. This opened my eyes to seeing if you really want something done, you can have it

The topic i choose was zero hunger, its so sad to think about the fact that we humans make enough food for all of us to eat comfortable, altough this fact is true, more the 800 million people go to sleep hungry on a daily basis. The root of this problem starts with the food waste we create, if we could fix that we should be fine for the years to come.

Coming into this topic, wind turbines in florida i was with the mindset that it wasn't very preveleant since i've lived in here basically my entire life and i havent seen a wind turbine like ever. Man was i wrong, i learned through some reaserch that its gonna become something prevelant. According to cleanenergy.orgTaller turbines and longer blades are capable of capturing more wind, which results in generating more electricity and reducing costs. In just five years, wind turbines have greatly evolved and are now more suitable for the Southeast.

I choose the first video "why the US isnt ready for clean energy" the point of the video is to explain that in order for us to have cleaner energy, we would need more re newable energy plants. What caught be by surprise was the fact of how expensive this would be somewhere around 400 millon dollars, which isnt cheap by any strech, but if its a country that can do it, its the US

Goal 2:We all know that going to sleep hungry isn't the best feeling, but did you know that more than enough food is produced to feed the entire global population? Regardless of this fact, as many as 828 million people around the world still go hungry. After researching I have concluded that the 3 main causes of hunger are Poverty, food waste, and lack of food. Did you know Paradoxically, every year, roughly one third of the food produced in the world for human consumption—approximately 1.3 billion tonnes—is lost or wasted.” If we just did a better job not wasting so much good edible food, i think this world issue can be resolved.

What caught ur attention and why?

what caught my attention is the amount of ways to get energy, and finding out the world uses 3trillon watts which is insane to think about. I learned that fossil fuels are a mane source of energy because of how efficent they are, but since we are running out, i think we should head in the direction of getting our energy from the sun and wind.
