Following the accident at the Fukushima Daiichi Nuclear Power Station nine years ago, the seniors started a water quality survey in the Chaya Marsh near the school and discovered Chara braunii , Nitella axilliformis Imahori, Closterium moniliferum, and Nostoc commune. According to the literature, these algae were found to adsorb Sr2+ and Cs+. Currently, it is about 180 tons of contaminated water continues to increase daily, and will not be able to be stored on site in the remaining two years. The government is considering releasing it into the ocean,. Therefore, we’d like to treat the contaminated water in the tanks with these algae and prevent it from being released into the ocean, so we took over the research from seniors and worked on it. The purpose of this study was to clarify the adsorption conditions for Sr adsorption of Chara braunii and the efficient Sr2+ absorption conditions of Closterium moniliferum, and predict the amount of evaporation using Nostoc commune, and to predicted how long for the treatment of Tritium water currently on site. Firstly, Chara braunii by varying the photon quantity to investigate crystals containing Sr could be formed. As a result, that the amount of photon quantum was increased, Next, using Closterium moniliferum, investigated the relation between Sr2+ absorption and photosynthesis, and it was verified that the Sr2+ absorption increased by immersion in BaCl2aq. The results showed that Sr2+ absorption was related to photosynthesis, and immersion in BaCl2aq increased Sr2+ absorption. Finally, we investigated the phenomenon of disappearing intracellular water into vapors by changing the wavelength and quantum amount in the Nostoc commune . As a result, it was confirmed more water was lost than natural evaporation during 4weeks. In addition, the treatment of Tritium water with Nostoc commune is expected to take about 10 years, and the possibility of treating contaminated water in a shorter period than to treatment with ocean release (about 40 years). In the future, we would like to proceed with verification toward the practical application of contaminated water treatment system utilizing these algae.

Abstract "When the Well is Dry, we will know the Worth of Water." Most of Egypt and the world suffers from water and petrol shortage. With the current consumption rate, two-thirds of the world's population may face water shortages by 2025. These are water pollution, overpopulation, and agriculture, leading to wastewater from landfills and pipes that seep into the ground and may pollute the water, making it unfit for human consumption and waste more water. Besides, some accidents happen to water distribution and irrigation systems, causing a significant loss in water. According to the ministry of water resources, in 2016, the need for freshwater is 67 billion cubic meters. On the other hand, Egypt receives only 55 billion cubic meters (2.6 billion cubic meters of them evaporate during runoff). Also, one of the wasting water methods in modern irrigation systems is water leakage from pipes as the water transmission and distribution lose about 31% of the produced water due to pipe leakage. Besides, Every day more than 3.3 billion liters of treated water – 20 percent of the nation's supply and 234 million liters a day more than a decade ago – are lost through leaking pipes in England and Wales. Many reasons lead to leakage in pipes like water pressure, clogs, and corrosion. The leakage in pipes does not exist in the lines of water only. Also, the pipes in a petrol can cause dangerous accidents like the accident in the Bahira government that led to the death of 6 people and made 19 in a dangerous state. Our project designed a system that can detect fluid leakage and deal with it fast to prevent the wasting of fluid by using sensors and electronic circuits. Our system provides us with information about the fluid (like the amount of the flowing fluid and its speed). Therefore, if there is a difference in the reads, we understand that there is a leakage in this region, and the system will automatically stop the fluid flowing through the pipes. the system will locate all the leakage sites and send them to the mobile app with the amount wasted and the actions taken.

There is approximately 4 billion plastic microfibers per square kilometer littered on the sea bed. These plastic microfibers are like poison to the aquatic life. This problem needs to be taken care of. The solution that we have is the U.G.C.S (Underwater Garbage Collecting System) . This device is an invention that is capable of cleaning the ocean floor in bulk in an innovative and efficient manner. It is a device which collects waste accumulated at the sea bed. It uses high-powered motors attached at the edges to navigate through the sea. It uses a variety micro-controllers as it’s brain. It also has two cameras at the top-right and bottom-left corners in order to locate areas with a high plastic micro-fiber concentration. It uses Lipo batteries as it’s power source. It’s body is made of Polycarbonate 3D printed plastic. It is coated in a waterproof material in order to prevent water from interfering with the electronic components.

Our oceans, coasts, and estuaries are home to diverse living things. These organisms take many forms, from the tiniest single-celled plankton to the largest animal on Earth, the blue whale. Understanding the life cycles, habits, habitats, and inter-relationships of marine life contributes to our understanding of the planet as a whole. Human influence and reliance on these species, as well as changing environmental conditions, will determine the future health of these marine inhabitants Humans influence the whole environment even if they don’t notice , the growth of men and our increasing reproduction over the years results to an over consumption of nutritious products , which makes us exploit the wildlife more and more and in the same time take parts of its habitats for us to life in and throwing our non-needed materials in what’s left of the world. And that’s a big problem because the Eco-System was just fine before we started over exploiting it in a greedy and unreasonable manner, and since the ecosystem’s parts are related altogether in an ongoing circle , the absence or the destruction of one part of It may lead to the unbalance and even destruction of the whole organized system. And that’s why as humans, it is our first duty to take care of nature generally and both fauna and flora specifically, not because of a moral code of some kind; but to protect Humanity from ourselves, and to preserve the human kind from destruction and extinction. And that’s the main goal of our project, that’s to help us organize our fishing exploitative activities with how much can the environment handle from it.
