Critical Reflection

At the start of this course, I thought this module would be like other communication modules in polytechnic. However, I found that this module was very engaging compared to others as there was more emphasis on interacting in class with each other. I learnt a lot about communication and critical thinking through this module. One key takeaway from this module I took is the skills to find information and properly cite them in my reports. I did not know much about how to find information for technical reports beyond just searching it up on google scholar. While doing the technical report for this module, I found that using key words for searching made it easier to find relevant information quickly. For citations, I was taught how to cite in polytechnic in my communication modules, but the importance of citation was never emphasized in polytechnic. Most of the time, just having a reference page with the links to the sources you took from was enough. The only times I had to properly cite my ...

Team Blitz technical report introduction draft 1

Singapore's overall waste disposed of 2,841 tonnes in 2020 while in 2019, Singapore had 2,984 tonnes. The overall waste disposal had been reducing since 2016. However, recycling rates were reduced from 59 percent in 2019 to 52 percent in 2020.  The current waste management system in Singapore is through public waste collectors appointed by the NEA to serve domestics and trade premises by geographical sectors. Waste collection vehicles are driven from location to location and collect waste from rubbish bins or HDB Centralised Refuse Chutes (CRCs). Subsequently, waste is delivered to waste-to-energy-plants or off-shore such as semakau landfill. Other than general waste collection, there are dedicated recycling trucks that only collect recyclables. Collected recyclables are sent to a Material Recovery Facility (MRF) to be sorted into different waste streams, and sent to local and overseas recycling plants. We define efficiency based on the money spent to haul the waste. The less money...

Summary Reader Response

The article “Scientists create living concrete from bacteria and sand”(2020) by Corless introduces the usage of bacteria in concrete mixes to make concrete that is able to take in CO 2 . Cement production contributes 8% of the world's carbon emissions. With how much we use cement in our construction projects and developing nations also using more concrete to build their nation, the search for greener alternatives to cement is key to sustainability. One alternative that could change our construction is the use of bacteria in cement to create "living concrete". The bacteria in the cement is a type of cyanobacteria that is able to perform photosynthesis. Corless(2020) explained "The team used a 3D sand–hydrogel scaffold that they inoculated with Synechococcus sp. PCC 7002 (Synechococcus) — a photosynthetic cyanobacterium that converts CO2 to sugars during photosynthesis. Cyanobacteria are well known to survive extreme environmental conditions, including high and low tem...

The article “Scientists create living concrete from bacteria and sand”(2020) introduces the usage of bacteria in concrete mixes to make concrete that is able to take in CO 2 . With cement production being one of the world’s leading contributors of CO 2 production, researching greener alternatives to cement production have become important to making construction greener. Many alternative production methods and substitute materials are being explored by researchers but so far none of them can provide cement’s desirable properties. Researchers from University of Colorado Boulder mixed sand, a hydrogel, and bacteria to create a living substance with the strength of cement-based mortar and the prospect to perform photosynthesis. The researchers used a 3D sand–hydrogel scaffold that they inoculated with Synechococcus sp. PCC 7002 (Synechococcus) — a photosynthetic cyanobacterium that converts CO2 to sugars during photosynthesis. Cyanobacteria are known for their ability to survive in extrem...

Soul of communication

Communication and critical thinking is vital for me. Poor communication will cause misunderstandings in the workplace. Both employees and employers have to be able to communicate effectively for the work to be done with minimal errors. Critical thinking is important for everyone especially leaders as it allows us to think rationally, identify problems and form a logical argument. This makes communication clear which allows the team to function. Both communication and critical thinking will be vital for me in the future as it will allow me to communicate my ideas properly. This will help in advancing my career as it shows what I am capable of to my employers.
