Carbon Cycle, City Food and Resources and Local, Whole and Organic Foods

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.

Efficiency in our City

Today, Malique, Dani, Antoine, Kamaya, and I were in charge of making houses. While we were making houses, we kept color reflectivity in mind. Albedo is the reflectivity of an object. Since we knew that the albedo of the color white is low, we planned to make that the color, of the roof. Unfortunately, we were not able to make the roof white today because of time. A pro of low albedo colors on roofs is that it can reflect the sun’s harmful rays off of the building which cools up the building and they do not have to use too much energy for air conditioners and/or fans which helps contribute to saving energy. Other than not being able to finish, today was a very fun day.

Soil Engineering

Hey blog! Today we talked about soil engineering with Chris. Soil engineering is one of the many jobs that civil engineers do everyday. To build on soil, there must be certain characteristics with the soil. The moisture and stability of the soil is important to know before building a bridge or any form of road. We tested out different types of soil and a combination to see the different states of soil. On Monday, we will see the progress of the different soils separating.


Natural Cycles and Water Waste Disposal and Filtration

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.

Cycles and Water Filtration

Today in Smart Cities, we learned about Earth’s natural cycles and Water Filtration. Some cycles we learned about were the rock cycle, the water cycle, and the carbon cycle. Each individual cycle is important to engineers for planning, designing, and building a city. Some facts about water are that 780 million people around the Earth don’t have access to fresh water, 3.4 million people a year die from water-related diseases, there are 366 Quintilian gallons of water on Earth, and a burger takes 2,700 gallons of water to produce. Also, the average American flush uses more gallons of water than people in third-world countries use per person. We then did an experiment with pH after discussing what it was. In the end, we filtered water with dirt in it to make it cleaner. Our water was barely cleaned, while some groups had theirs looking almost like water.


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.
