This document provides information about Marfan syndrome, a genetic disorder of the connective tissue. It affects multiple body systems including the eyes, cardiovascular system, and nervous system. In the eyes, it can cause lens dislocation and retinal detachment. In the cardiovascular system, it weakens the aorta wall and increases the risk of aortic aneurysm or dissection. In the nervous system, it causes the dura surrounding the spinal cord to stretch and put pressure on the vertebrae. There is no cure for Marfan syndrome, but regular checkups and early detection/treatment of issues can help manage risks. Lifestyle adjustments and sometimes surgery may be needed depending on the specific problems present.
What is expected from the Group 4 project?
1. Interdisciplinary collaboration
2. Appreciation of the implications of science and the limitations of scientific study
3. Development of teamwork
4. Development of planning skills
5. Exchange or sharing of both data collected and issues raised.
6. Approximately 10 hours of involvement time

Anthropogenesis is the genesis or development of the human race, especially as a subject of scientific study.
Hominization, also called anthropogenesis, refers to the process of becoming human and is used in somewhat different contexts in the fields of paleontology and paleoanthropology, archeology, philosophy, and theology.
Understandings:
Most species occupy different trophic levels in multiple food chains
A food web shows all the possible food chains in a community
The percentage of ingested energy converted to biomass is dependent upon the respiration rate
The type of stable ecosystem that will emerge in an area is predictable based on climate
In closed ecosystems energy but not matter is exchanged with the surroundings
Disturbance influxes the structure and rate of change within ecosystems
Applications:
Conversion ratio in sustainable food production practices
Consideration of one example how humans interfere with nutrient cycling
Skills:
Comparison of pyramids of energy from different ecosystems
Analysis of a climograph showing the relationship between temperature, rainfall and the type of ecosystem
Construction of Gersmehl diagrams to show the inter-relationships between nutrient stores and flows between taiga, desert, and tropical rainforest.
Analysis of data showing a primary succession
An investigation into the effect of an environmental disturbance on an ecosystem

Understandings:
The distribution of species is affected by limiting factors
Community structure can be strongly affected by keystone species
Each species plays a unique role within a community because of the unique combination of its spatial habitat and interactions with other species
Interactions between species in a community can be classified according to their effect
Two species cannot survive indefinitely in the same habitat if their niches are identical
ATL / Approaches to teaching and learning /Mariam Ohanyan
Inquiry-based Learning includes teaching methods built on students' individual knowledge and interests and emphasizes learning how to learn and how to find out, using both traditional and contemporary media. Each teacher has the mandate that the learning within their classroom must be engaging, relevant challenging and
Այս սահիկաշարը ստեղծվել է ավագ դպրոցի սաների և ուսանողների համար, որոնք արժևորում են գիտության մեջ հետազոտական աշխատանքի կարևորությունը: Այն հնարավորություն է տալիս առավել լավ պատկերացնել ՙՙվարկած՞՞ և ՙՙփոփոխականներ՞՞ հասկացույունները և հետազոտական հարց, վարկած ձևակերպելու ուղիները:
A clade is a group of organisms that have evolved from a common ancestor.
Cladograms are tree diagrams that show the most probable sequence of divergence in clades.
Evidence for which species are part of a clade can be obtained from the base sequence of a gene or the corresponding amino acid sequence of a protein.
Sequence differences accumulate gradually so there is a positive correlation between the number of differences between two species and the time since they diverged from a common ancestor.
Traits can be analogous or homologous.
Evidence from cladistics has shown that classification of some groups based on structure did not correspond with the evolutionary origins of a group or species.
The binomial system of names for species is universal among biologists and has been agreed and developed at a series of congresses.
When species are discovered they are given scientific names using the binomial system.
All organisms are classified into three domains.
Taxonomists classify species using a hierarchy of taxa.
The principal taxa for classifying eukaryotes are kingdom, phylum, class, order, family, genus and species.
In a natural classification, the genus and accompanying higher taxa consists of all the species that have evolved from one common ancestral species.
Natural selection can only occur if there is variation among members of the same species.
Mutation, meiosis and sexual reproduction cause variation between individuals in a species.
Adaptations are characteristics that make an individual suited to its environment and way of life.
Species tend to produce more offspring than the environment can support.
Individuals that are better adapted tend to survive and produce more offspring while the less well adapted tend to die or produce fewer offspring.
Individuals that reproduce pass on characteristics to their offspring.
Natural selection increases the frequency of characteristics that make individuals better adapted and decreases the frequency of other characteristics leading to changes within the species.

Evolution occurs when heritable characteristics of a species change.
The fossil record provides evidence for evolution.
Selective breeding of domesticated animals shows that artificial selection can cause evolution.
Evolution of homologous structures by adaptive radiation explains similarities in structure when there are differences in function.
Populations of a species can gradually diverge into separate species by evolution.
Continuous variation across the geographical range of related populations matches the concept of gradual divergence.
Personal Project Guide by Mrs. Mariam OhanyanMariam Ohanyan
The Personal Project is an independent assignment that can be on any topic and take any form as long as it has a strong connection to one Area of Interaction. If you choose the right Personal Project, it will give you the opportunity to share with others something that is important to you, and it will be an exciting and rewarding experience.
It is your project that demonstrates the skills you have developed over the years in the Middle Years Program (MYP). The Personal Project holds a special place of importance in the MYP, as it is a culminating even which is completed in the final year of the program (Grade 10).
You will be working on your project over the course of many months, so be sure you pick a topic in which you have a strong interest or genuine curiosity. The project will consist of the actual project, the process journal that documents your ideas and work throughout the project, and the personal report which will be summarize your overall experience.

С каждым годом на нашей планете становится все
меньше и меньше диких животных. И это понять
нетрудно: увеличивается количество населения в мире,
а чем больше людей, тем меньше места для обитания
животных.
3.
Кое-кто может подумать, что животные
исчезают только из-за охоты человека на них. Однако
без рациональной и обдуманной охоты, регулирующей
численность птиц и зверей, вряд ли сейчас
существовали бы косули, олени, сайгаки. Многие виды
животных исчезают от косвенного влияния человека
на их жизнь. Дело в том, что человек невольно
отнимает у своих «меньших братьев» естественные
места обитания животных, их кормовые участки.

Сейчас важно сохранить любой вид животных,
которых природа создавала в течение долгих миллионов
лет.
5.
А зачем надо сохранять диких, особенно редких и
исчезающих животных? Пожалуй, над этим вопросом
многие не задумываются. Но если и подумают, то и
ответ для него находят быстро: если животных какого-
то вида так мало, то они, видимо, не имеют никакого
значения в природе, так что и после их исчезновения
жизнь на Земле не остановится. Ведь таких примеров
история знает немало. Однако те, кто так думает,
глубоко заблуждаются.
6.
Дело в том, что фауна нашей планеты —
это не случайное скопление различных
видов животных, а единая, согласно
функционирующая система и выпадение
любого, самого незначительного на
первый взгляд звена ведет к серьезным
изменениям.
7.
Чтобы сохранить богатство живой природы Да еще
умножить его, человеку предстоит многое сделать.
Правительство заботится об охране и
воспроизводстве животного мира с первых дней своей
власти. Установлены основные требования охраны и
рационального использования животного мира,
определены виды использования животных, в
частности охота, рыболовство и другие.
8.
В нашей стране ведется большая работа по
обогащению и охране природы, а успех этого во
многом зависит от каждого из нас.
Как сохранить диких, особенно редких и исчезающих
животных? Эту проблему решают ученые во многих
странах мира.
9.
Животный мир является одним из основных
компонентов природной среды, важной составной
частью природных богатств нашей Родины. Он служит
источником для получения промышленного,
лекарственного сырья, пищевых продуктов и других
материальных ценностей, необходимых для
удовлетворения потребностей населения и народного
хозяйства нашей страны. Кроме того, животный мир
используется в научных, культурно-просветительских
и эстетических целях.
13.
Роль животных в биосфере и жизни человека
чрезвычайно велика.
Разнообразие видов животных полезно для человека.
Они служат источниками питания, технического и
лекарственного сырья, хранителями генетического
фонда для улучшения пород домашних животных.
