Sharing about the reason for choosing to travel independently, Ty said: “Perhaps it is because I want my youth to be a little different. Before every trip, I have a feeling of fear, but after overcoming it, I want to go to more places. And another reason, there is a sister I know who inspired me with self-sufficient travel trips. She’s a girl, but if she’s brave like that, I can do it too!” Self-sufficient travel helps Ty balance in his studies. (Photo: NVCC) Nguyen Ty affirmed that she had conquered her limits or the things she thought she couldn’t do, and then she wanted to conquer more and more goals. Talking about the trip that left the most emotions in Ty, the friend was not afraid to share about his trip to Y Ty (Lao Cai). “Initially, I went “trekking” (in the form of hiking or climbing mountains, crossing all kinds of terrain) Lao Than in Y Ty. Due to the influence of the storm, it rained and thanks to this chance, I met two very interesting people, Uncle Lee and Ms. Van in Y Ty. After sharing a meal, I invited them to join for fun. During this trip, I experienced a lot of things like the landscape of the high mountains, how life in the mountains lacks electricity because I only use electricity while eating the rest, I have to light a fire in the kitchen to keep warm. … And the trekking journey of Lao Than in the rainy and stormy season is not easy, I slipped and fell several times when climbing the slippery slopes. However, this trip left me with a hobby of trekking, maybe in the future I will continue to go to the mountains higher than Lao Than”, Ty recalled. Photo Bill “Chill” at a coffee shop in Da Lat. In such self-sufficient tours, Ty made many mistakes because of his lack of experience. Billion shared: “Once, I booked a room on the wrong date, but fortunately, I was supported to change the date at no extra cost. There were times when I didn’t preview the weather forecast, so when I got there, I didn’t get much harvest. And even the times of not carefully calculating in terms of health to visit many places.” Ty’s memorable climb to Lao Than and Y Ty with new friends. Also from those mistakes, Ty has learned many valuable lessons for himself. From scheduling and organizing a reasonable plan, managing expenses, expanding relationships and connecting with people, he also has the opportunity to learn more about the culture in many different lands. listen directly to the story told by the natives. “Go a day, learn a smart sieve” and so, Nguyen Ty becomes more and more active and confident to conquer new destinations in the future. “The most important thing is to determine the route. , calculate and reserve costs if risks arise. If it’s your first time experiencing, you can choose places that are a little closer to you to be less surprised, and slowly go further. Ask people who have traveled alone many times what questions you still have. In my opinion, in today’s open world, it’s not too difficult to look up and prepare for the schedule. Every time I prepare to go, I go to pages like: Skyscanner, Booking.com, Vexere, DSVN… to see flights, train tickets, bus tickets, accommodation …”, Bill “reveals” the experience for those who travel independently for the first time. Trieu Dao Nguyen Ty always knows how to balance traveling and studying, so during high school, you have achieved some “terrible” achievements such as: Traditional Olympic Silver Medal 30/4 times XXIV Geography, Traditional Olympic Gold Medal 30/4 times XXV in Geography, First prize for Excellent Student in the City in Biology.

Female scientist – Dr. Lu Thi Ngan (born 1983), working at the Department of Biology, Vietnam Museum of Nature, Vietnam Academy of Science and Technology is a female scientist of Thai ethnicity, born and raised in a highland district in western Nghe An . Since childhood, she has been associated with the farming life and nature. Maybe that’s why her love for forests and trees has existed for a long time. Dr. Lu Thi Ngan on a trip to find ferns in Pu Luong, Thanh Hoa Dr. Lu Thi Ngan “In the past, when I was a child, I ate sticky rice every day, so I was very healthy. In the early morning, I often followed my grandfather, my mother went to the forest. Everyone worked in the fields, and I sat next to the fields and waited until dark to return to the village. That day, I couldn’t speak Kinh fluently.” She added, fortunately when she was in high school, she was sent to study at the Central Ethnic Minority Boarding School located in Thai Nguyen. Her love for nature is infiltrated in her blood, so she is particularly interested in Biology and won the National Encouragement Prize for excellent students. Entering university, Dr. chose the Faculty of Biology, University of Natural Sciences, Vietnam National University, Hanoi and went to work at the Vietnam Museum of Nature upon graduation. Here, she decided to choose to study ferns, a small group of plants that are not of much interest. Dr. Lu Thi Ngan said that not only has no scent, no color, no flowers, fruits, and ferns, it is also a very difficult industry to study because the morphological characteristics change a lot, many features require a new magnifying glass and microscope observed, moreover, for this industry, there are very few researches in our country, so there is a lack of databases for reference. That’s not to mention, except for a few species of ferns that grow wild on the street that we often see, most of the unknown ferns grow in high mountainous areas, rugged limestone mountains. “But I still love ferns, because they have a fragile beauty with a hidden vitality,” she asserts. The “terrible” values Dr. Lu Thi Ngan said that although there is no fragrance, no color, no flowers or fruit, the fern brings values ​​that many people cannot imagine. Dr. Lu Thi Ngan on a field trip. Ferns are a group that plays a very important role in evolution and biodiversity because they are widely distributed and occupy many habitats. “This is the second largest group of vascular plants and one of the first terrestrial plants to appear, about 300-400 million years ago,” she said. In addition, ferns have many uses in everyday life. Few people know that ferns are a source of food containing a lot of nutrients. Some species of ferns such as bud, bubble, cow’s hoof… are valuable and nutritious food sources. The berries of some ferns can also be eaten to combat thirst. Many species of ferns can be used for ornamental or decorative purposes, and even the fibers of the fern can be exploited to make handicrafts. In particular, phytochemical studies on ferns have revealed that they contain many valuable substances that can be used to make medicine. On the market, there have been many medicinal products and functional foods derived from ferns such as sunscreen pills, hair growth shampoos, decoction forms to help increase resistance when infected with viruses, improve symptoms. dementia (Alzheimer). Not only the fern has “terrible” value, but the researches of Dr. Lu Thi Ngan about ferns is also very “terrible”. After more than 10 years of silent research, until now, Dr. Lu Thi Ngan has announced 5 new genera, 30 new fern species for science and 37 additional species for the flora of Vietnam. Her research results have contributed significantly to the worldwide community of fern scientists. At the same time, these results also help to enhance and confirm the biodiversity value of ferns in Vietnam. Every job has its own feelings There are consecutive articles published in domestic and foreign journals, including famous international journals, there are continuously announcements of new species discovery, but behind these are difficulties and difficulties. problems of scientists, especially female scientists. With Dr. Lu Thi Ngan every job has its own difficulties and hardships. Dr. Lu Thi Ngan said, up to now, she can’t remember how many field trips she has gone through, how many forests, and how many mountains she has climbed. But these trips are nothing compared to the time when she decided to go to Chengdu Institute of Biology, Chinese Academy of Sciences to be a PhD student. At that time, her life partner was Dr. Do Van Truong, who works at the Vietnam Museum of Nature, is working as a PhD student in Germany. And my daughter just turned 3 years old. It was like that for a few years as a family of three in three places. Recently, on his personal Facebook page, Dr. Lu Thi Ngan posted a photo of the three of them on her husband’s birthday with the caption, “This is the first time the whole family is together on a special occasion.” The line of confession is enough to understand the hardships of scientists. However, Dr. Lu Thi Ngan is very calm. For her, every job has its own difficulties and difficulties. The important thing is that I know how to overcome to do my job and love it. For her, doing science is not only a job but also a passion and certainly in the coming time, researches on Vietnamese ferns will continue to be published in international journals.

12th grade students AT.1 Gia Dinh High School in Biology class. Illustration Ecology (Biology grade 12) is the part with close knowledge, easy to deduce, so it can be called “easy”. However, the amount of knowledge in this section is very much, so if not codified, it will be “difficult”. Ecology section consists of 3 chapters, 11 lessons, students need to systematize knowledge and understand ecological terms. Specifically in Lesson 35 Habitat and ecological factors , in Chapter I Individuals and biomes , students need the system of ecological factors to include Infertility factor (physical factor and chemical factor) and the existential factor (the organic world and the relationship between organisms). The example in the reference year 2021 Question 87: Which of the following ecological factors is the infertility factor? A. Worm. B. Light. C. Worms that eat rice leaves. D. Rice plants. We can easily know that answers A, C, D belong to the existential factor, and answer B is the physical factor – the infertility factor. Besides, we need to understand about ecological limit and ecological drive. In the ecological limit, it is necessary to know the tolerance interval, the favorable interval, the lethal point, the positive point and we can adopt the example of the ecological limit of Tilapia for easier understanding. Students need to be able to distinguish ecological drive and accommodation to avoid confusion we can remember accommodation is just a place of residence still Ecological drive shows the way that species lives. Next, we need to note about the adaptation of the organism to temperature, it is necessary to understand the two Principles of Becman and Alen. Becman’s Rule tells us that “Thermostats live in temperate regions larger body size compared with animals of the same species or closely related species living in warm tropics. We can remember quickly “Body size: animals in temperate> tropical animals”. About the Anlen rule “ Tropical animals that live in temperate regions have ears, tails, and limbs usually smaller ears, tails, and limbs of similar animals living in hot regions ”. Can remember quickly “ Sizing of parts: tropical animals> temperate animals “. Students in grade 12AT.1, Gia Dinh High School are making mind maps for lesson 35 One of the content that frequently appears in the exam is Lesson 40 Biomes and some basic features of biomes. First of all, they need a system of relationships between species in a community. Example from 2021 references Question 89: In biomes, which of the following ecological relationships belong to the supportive relationship between species. A. Parasites. B. Inhibition – sensitization. C. Competition. D. Symbiosis. When the systematization is easy, we can immediately choose the answer D. At the same time, it is necessary to understand relationship forms and take illustrative examples to easily remember. Test papers often give specific examples asking what relationship it is? Example from 2021 references Question 95: During the breeding season, females in the stork population compete for a favorable place to nest. Here’s an example of a relationship A. competing for the same species. B. supporting the same species. C. Assembly. D. cooperation. Based on the title “female individuals in the stork population” meaning “of the same species”, they “contested”. , We conclude this is an example of a competitive relationship with a species. So for this type of question, we rely on phrases, keywords, and clauses of the question to make inferences. The next and most frequently appearing examples on the test are food chains and food webs. Regarding the food chain, we need to note that there are two types of food chains: the food chain starts from the autotrophic organism and the food chain starts from the organic humus decomposing organism. In food chains and webs, it is easy to confuse the “number” between the nutrient level and the consuming organism. Illustration : Floating plants -> Invertebrates -> Small fish -> Large fish Floating plants are organisms that produce a level 1 nutrient Invertebrates are a primary consumer but are a tier 2 nutrient. Small fish is a tier 2 consumer but is a tier 3 nutrient. Larger fish are tertiary consumers but are a level 4 consumer. Example from 2021 references Question 103: Feeding the food chain: Rice plants Deep eating rice leaves Field frog Hawthorn cobra. In this food chain, which organism belongs to the tertiary consumer group? A. The hawk. B. The bronze frog. C. Worms that eat rice leaves. D. Cobra. With a clear understanding and clear knowledge system, it is easy to identify the Cobra as a third-order consumer. Through basic analysis of the above contents, we easily recognize one thing: Knowledge of Ecology is not difficult, just systematized by mind maps, images, tables, … then we easily solve the questions in the exam. Please plan to systematize your knowledge with mind maps for the Ecology section to do well the 7 questions of Ecology in the high school graduation exam. Based on the 2021 high school graduation exam illustrative exam questions, we can see that the Genetic Mechanism and Variation 9 sentences (with 1 sentence of high application), The genetic rule has 10 sentences (4 sentences with high volatility 2-sentence population genetics (1 sentence highly manipulated), 1-sentence application of genetics, 1-sentence Genealogy genetics, 6-sentence evolution (1 sentence to apply), 7-sentence ecology (1 sentence and Biology in Grade 11 has 4 sentences. Thus, basic knowledge is 7.5 points, applying 1.5 points low and applying 1 point high. We can see that the content of Biology subject with a huge amount of knowledge, to facilitate learning and review students need to systematize knowledge is essential. If students have a clear study and study plan, scoring 7-8 is entirely possible.

At the National Science and Technology Contest for high school (HS) students of the 2020-2021 school year organized by the Ministry of Education and Training in Thua Thien Hue province in March, Trang Si Thai and Nguyen Tran Thanh Ngan – Grade 11B student Ly Tu Trong High School (Nha Trang City) won the third prize with The Plantae software – identifying and providing scientific information of plants. Plant identification applications With the desire to help students find more quickly and effectively about trees …, Thai and Ngan came up with the idea of ​​writing application software to help users identify and support information as well as the uses of species of herbs, plants … The two children said: “Currently, there are many plant identification products on the market, but few students pay attention and use them in learning. Therefore, we want to provide an easy and convenient way to access information flow, and at the same time increase students’ knowledge about these plants ”. The teacher instructed Thai and Ngan to study the rose tree. The software is written for the Android and iOS platforms with 2 main languages: English and Vietnamese. The mechanism of this application is that when the captured image is processed in many steps. After the image is sent to the server, the image will be analyzed and recognized. If the name matches the tree species in the system, the data about that plant species will be retrieved. In August 2020, Thai and Ngan software were officially published on the Google Play store for the Android platform under the installation link: dstteam.com/App-ThePlantae. In the process of implementing the project, the 2 students met many difficulties. “Our biggest obstacle is finding a source of medicinal herbs for analysis. In addition to the available medicinal plants being grown on the school campus, we have to actively seek and ask the guidance of the teacher to have more different species of plants outside, helping with the experiment. the software is more accurate ”, Thai expressed. Teacher Nguyen Lam – instructors Thai and Ngan said: “As teachers of Biology, to help them do scientific work and have extensive knowledge for each plant is one of the important steps. Therefore, I have supported and directed the two children to create diagrams of plant species so that they can synthesize all the knowledge of the curriculum quickly and effectively ”. 4,000 people installed and used Through nearly 10 months of development, The Plantae application on Android has been optimized and has about 4,000 people installed and using. The application supports users to recognize more than 12,000 species of herbs and plants. In addition, this application provides more information to the user about that plant species; Treatment directions for some species … Instructions for installing the software The Plantae. Mr. Lam said: “After the national science and technology competition, the software has been continuously updated, developed, and upgraded with new features to achieve more efficiency, smoother and more accurate … Currently, this application has been widely used by students; especially for students specializing in block B in the process of learning and searching information about plants, medicinal herbs … “. According to Thai and Ngan, in order to better support users, the software should be further researched and improved to improve the accuracy and speed of recognition processing. In addition, data on software also needs to be updated, so that, image data and scientific information about plants will be more complete and accurate. It is expected that in the near future, The Plantae will assist users in assessing the health status of plants, giving better instructions for plant care. THANH TRUC
