Today, I learned about Smart transportation systems like by reducing the use of gases such as methane and CO2. I learned mass transit is more effective than personalized vehicles because they allow large numbers of people to travel long distances using the least amount of fuel possible. I also learned about new innovative ways scientists are trying to improve public transportation through the SMT rail and Straddling bus. The SMT rail involves a single rail with a car attached. when payment is given the car arrives at the stop/location you wish to be at then lets you off. Similarly, the Straddling bus, is a double layer bus that allows cars to pass through underneath to reduce congestion caused by large vehicles. I also learned about Smart Highways and Cars. I learned that by making cars aerodynamic,convenient, safer, and with higher fuel economy, cars become more efficient. Towards the end of the day, i found out that depending on the material used as pavement, either cement or asphalt, can change the durability and smoothness of the road. While cement is more durable, asphalt is smoother and in the long run, more expensive.
I learned about the Carbon Cycle, the process in which carbon is exchanged throughout the earth. Carbon cycles through the Biosphere, Pedosphere, Geosphere, Hydrosphere, and Atmosphere through respiration emissions, photosynthesis, and ocean uptake. Photoplankton absorbs carbon and transfers it through the sea’s ecosystem. I also learned about the difference between Local, Whole, and Organic foods. Local food is food made in the neighborhood. Whole food is food shipped from outside the state or country. Organic food is food without preservatives and pesticides. Finally, I learned about City food and resources, essentially, the things required or needed to create a functionally operating city. Markets, government , and reactions to disasters are important parts of a city as one provides food, leadership and ways to deal with problems we cannot control.

I learned about the natural cycles that occur in the world such as the carbon cycle, water cycle, and the rock cycle. The carbon cycle is the transfer of carbon throughout the environment. Carbon travels through trees, oceans, soil and the sky. The water cycle is when water evaporates and condenses, the precipitation occurs releasing the water stored in the clouds. Finally, the water runs off and the process begins again. In the rock cycle, rocks change from Igneous, Metamorphic, and Sedimentary rocks.
Towards the end of the day, we learned pH and water waste removal and filtration. PH is the measurement of hydrogen ions content in a substance/measure of acidity. Water Waste Disposal is the process in which dirty unclean water, not grey water, is filtered back into tap water that can be reused in homes. resin is used to attract dirt together which allows it to be removed. The dirty water is mixed and filtered. Finally, chlorine is added to purify the water. It is then distributed to every day homes for use. I also learned that continuous filtering of dirty water gradually cleans out dirty particles within the water.

Today, I traveled to the Museum of Natural History and observed many exhibits with my group I learned that dinosaurs are considered dinosaurs because of the positioning of their hip bones and that their spines continue through their tails. I also learned that universe was started by dark matter that caused the Big Bang. At the space exhibit I learned that the galaxy included all matter and space. At the Global Kitchen exhibit I learned that food from all over the world comes together to create the everyday dishes that we eat. Finally I learned that birds especially ostriches resemble dinosaurs because their hip bones are similar and that they had feathers at the tops of their heads just lie dinosaurs.

Today at SoSC I learned about problems like global warming and climate change, Geoengineering, Power Storage, and renewable ways to create renewable sources of energy. In the beginning of class we learned that global warming and climate change have disastrous effects on the earth. They increase the earths overall temperture, killing off animals living in the polar ice caps, cause droughts, and natural disaters all over the world. we also learned about Geoengineering, or earth engineering. I learned that Greenhouse Effect disturbs the Earth’s process of reflecting the suns UV rays. I also learned that it also decreases the earth’s albedo, or its reflectivity to sunlight. we learned ways scientists are trying to combat the problems of cllimate change with Cloud Seeding the Algae Street Lamp, and Ocean Seeding. Cloud Seeding boosts the earth’s ability to reflect sunlight while the Algae street lamp decreases the amount of Carbon Dioxide in the environment. Towards the end of the day, I learned about power storage. I learned that I should save as much energy as possible and ways to improve our energy grid by incorporating network communication. At the end of the day we learned about new renewable resources like a hydrogen fuel cell. I did an activity in which I demonstrated the workings of a hydrogen fuel cell. i used nickel plates placed in water connected too a battery. This created a reaction thaat seperated the H2O into H2 and O. The H2 is used to generate energy. This produces no harmful waste and is a efficient way to generate cleaner electricity.
