Satellites and Space Stations

Today we learned about satellites and how they are made to go around a specific orbit. Also, about the names of each orbit. We also learned about the INTERNATIONAL SPACE STATION. It takes the space station about 90 minutes to just go around the EARTH once.  That way it’s able to outrun the EARTH and stay in orbit.  We also kept building with the LEGOs. Today i helped build the NUCLEAR POWER PLANTS, it wasn’t easy building it but after some work we came up with some good ideas and finally finished it. It still needs some final adjustments, but those will be made next time we work on the city.

Renewable Energy

Today in Science of Smart Cities, we learned about power generation. First we had a brief discussion of nonrenewable and renewable energies. Then we learned about the various sources of energy (hyrdo-electric, solar, nuclear, etc.). Then, we talked about the location of the power plants. After that we learned how nuclear, solar, and wind energies function properly. After that we had a huge assignment; to create a hydro-electric generator. My group contained Hafsah, David, and Erlyn. The three parts were wrap coil around the 8 holes in one part. Then, glue 7 magnets into 7 holes. Finally, glue pieces to a cylinder-like object to create a turbine. We are presenting tomorrow!

 

Geo-Engineering

Yesterday we learned about Geo-engineering which is a branch of civil engineering concerned with developing technologies to reduce the effects of climate change. We learned about cloud seeding which is when people use this boat to make water vapor which will make the clouds denser so that the clouds could reflect harmful rays to reduce the effect of global warming and climate change. But my favorite thing that we learned was is about the Algae which produces 80 percent of the worlds oxygen (O2). In the future we will have algae lamps that does not run on electricity, it glows in the dark, and it helps people breathe better.

Power Generation

Today we learned about different ways power plants create electricity. Also, how Wind or Water turns a mill which gives power to magnets and makes them spin which makes a Turbine spin which sends electricity to a place which distributes the electricity to different places. To add on, today we also did an activity where we built a HYDROELECTRIC model of a real HYDROELECTRIC POWER GENERATOR. We also learned that New York and other states use the NIAGARA FALLS as a HYDROELECTRIC power source.

 

Renewable Resources and Geoengineering

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.
