Welcome to my academic blog! My name is Chehwan Kim. This blog will keep track of my high school life and academic activities.

Introduction Really feels like this post should have been the first one, apologies for that. I want to focus on introducing the concept of aquaponics in general. So What Is It? Aquaponics combines aquaculture with hydroponics. In this system, fish are raised in tanks, and plants are grown without soil. The nutrient-filled water from the … Read more
Introduction Aquaponics is an interesting concept, accessible to anyone. It is an eco-friendly, efficient, smart way of growing plants and fish, at the same time. This post, rather than focusing on the social aspects of aquaponics, will dive into a bit of biology. What nutrients are given by fish to plants? Ammonia is used here. … Read more
Introduction Aquaponics requires us to monitor certain factors for the system to run well. This can be done by human work, but it can also be automated by using Arduino Uno. What to do I would like to explain what the system is and what the benefits are. I intend to use an Arduino Uno, … Read more
What is this new type of experiment? From the sources that I read about hyrdoponics, aeration was important for the plants to get enough air. It also prevents bacteria and algae from growing, which is the same reason why we can drink flowing water but not still water. In the first method I did, which … Read more
Both the kale and lettuce have died. It could be because it did not get enough sunlight. It was right next to a window but the window was a little above the plants. It could also have been because I stopped giving it water. It’s true hyrdoponics do not constantly need to be watered. However, … Read more
Documentation The plants are growing more and we can start to see the stem. Impressions I’m glad that results are showing right away. Both the kale and lettuce are going well. After a day or so, when the stems start to grow over 2cms, I should pick out some of the seeds that have sprouted. … Read more
Why I Started this Activity Aquaponics is a way to grow plants and raise fish at the same time. The method produces food with less arable land, less pollution, and less resources used. I grew a lot of interest in that method, and researched some information about it. Hydroponics is not the same as aquaponics. … Read more
