The tropical rainforest is a unique ecosystem with constant high temperatures and rainfall. This creates a unique water and nutrient cycle. However, rainforests are threatened by human expansion and activities like agriculture, mining, and infrastructure development which can lead to deforestation and environmental degradation. While these activities may provide short-term economic benefits, they often come at the cost of significant environmental damage and loss of biodiversity.
Mangrove forests are ecologically and economically important and provide services to humans. Yet they are one of the most threatened ecosystems partially due to deforestation. Frequently dominating protected coastal areas in the tropics and subtropics at suitable inter-tidal zones are often subjected to disturbances that disrupt the structure of an ecosystem.

LINES ON THE GLOBE
Basic Understanding
1) Latitude – distance between two parallels measured north or south of the Equator.
2) Longitude – distance between two meridians measured east or west of the Prime Meridian.
3) Meridians – are imaginary lines that meet at the poles.
4) Parallels – are imaginary lines running in an east-west direction around the Earth.
5) Meridians and parallels – are imaginary lines that help in establishing locations of places on Earth.
Lines refer to “parallels and meridians”.
Distances refer to “latitudes and longitudes”.
Parallels of Latitudes
Equator – parallel located at the center and whose length is equal to the circumference of the earth.
Great Circle – largest parallel, the only Great Circle among the parallels.
Special Parallels
Arctic Circle – located at 66 ½ o north of the equator. It marks the northernmost limit of the Sun’s oblique or slanting rays.
Tropic of Cancer – lies 23 ½ o north of the equator. Marks the northernmost limit of the Sun’s vertical rays.
Equator – designated Oo latitude, located at the center of the Earth and divides the Earth into the Northern and Southern Hemispheres.
- The reference point in measuring distances north and south moving toward the poles.
Tropic of Capricorn - lies 23 ½ o south of the equator. Marks the southernmost limit of the Sun’s vertical rays.
Antarctic Circle - located at 66 ½ o south of the equator. It marks the southernmost limit of the Sun’s oblique or slanting rays.
Meridians of Longitudes
Meridians – line running vertically about the Earth.
• Two meridians opposite each other form a Great Circle.
• Meridians are arcs of Great Circles.
SPECIAL MERIDIANS
1. Prime Meridian – line designated Oo longitude and which passes through Greenwich, England. Also called Greenwich Meridian.
- It is the reference point in measuring distances eastward or westward.
2. International Date Line (IDL) – directly opposite of the prime meridian in a line designated 18Oo longitude.
- It is not a straight line that deviates eastward and westward upon crossing certain places to allow land areas and island groups to have the same calendar day.
This is a PowerPoint Presentation by my second class at the Cape Fear Center for Inquiry in Wilmington, North Carolina. . This presentation reflects an inquiry continuum within the thematic unit of geography. The students began by recalling what they already knew about the seven continents and then asked questions to shape their research. Students also discussed what research sources would most helpful to answer their questions. After two sessions of small group work in the computer lab, students created PowerPoint slides to synthesize their findings. This was a challenging but age-appropriate project because students had to also work cooperatively in collaborative groups, use technology responsibly and implement design ideas to support their final product

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. The tropical r ainforest is a unique biome with a constant temperature and a high rainfall. The level of humidity and denseness of the vegetation give the ecosystem a unique water and nutrient cycle. Rainforests around the world are threatened by the expansion of man.
3.
4. In general, tropical rainforests have hot and humid climates, where it rains virtually everyday. At some parts of the year the rainfall is extremely heavy, while in other parts of the year it will rain a lot less. Temperatures vary through the year - but much less than the rainfall. The graphic shows average rainfall and temperature in Manaus, Brazil, in the Amazon rainforest. Total rainfall is 2104mm per year, most of it during the rainy season from December to May. Notice how much the rainfall varies over the year: the highest monthly rainfall is in March with over 300mm, while the lowest is in November with less than 50mm. Meanwhile the temperature only varies by 2°C.
5. The shrub layer is at ground level in a tropical forest. It is dark and gloomy with very little vegetation between the trees. During heavier rainfalls this area can get flooded. The Under canopy is the second level up. There is limited sunlight. Saplings wait here for larger plants and trees to die, leaving a gap in the canopy into which they can grow. Woody climbers called lianas av oid having to wait for gaps by rooting in the ground and climbing up trees to get to the sunlight. The Canopy is where the upper parts of most of the trees are found. The canopy is typically about 65 to 130 feet (20 to 40 metres) tall. This leafy environment is full of life such as insects, arachnids, birds and some mammals. Emergents are the tops of the tallest trees in the rainforest. These are much higher, and give the trees an advantage (in terms of light) than the average trees that populate the forest canopy.
6. Vegetation in the rainforest has evolved characteristics which help it survive in this unique environment. Here are some examples:- Fan Palms Fan palms have large, fan-shaped leaves that are good for catching sunshine and water. The leaves are segmented, which allows excess water to drain away.
7. Buttress Roots Rainforests have a shallow layer of fertile soil, so trees only need shallow roots to reach the nutrients. However shallow roots aren't great for supporting huge rainforest trees, so many tropical trees have developed huge buttress roots . These stretch from the ground to two meters or more up the trunk, which help anchor the tree to the ground.
8. Lianas Lianas are woody vines that start at ground level, and use trees to climb up the canopy where they will spread from tree to tree to get as much light as possible.
9. Strangler Figs Strangler figs start at the top and work down. The seed is dropped in a nook at the top of a tree where it starts to grow, using the debris collected there. Gradually the fig sends aerial roots down the trunk of the host, until they reach the ground and take root. As it matures, the fig will gradually surround the host, the aerial roots will criss-cross the trunk and start to strangle. Meanwhile the figs branches will grow taller, dominating the sunlight, while invasive roots rob the host of nutrients. Eventually the host will die and decompose leaving the hollow, but sturdy trunk of the strangler fig.
10. Rainforest water and nutrient cycles Rainforest ecosystems are characterised by heavy convectional rainfall , high humidity and lushness of vegetation, and nutrient-rich but shallow soil. These factors give rise to a unique water cycle and nutrient cycle .
14. Humans intervene in tropical rainforests in order to bring real or imagined benefits to themselves or the local population. The short-term benefits of clearing rainforest areas usually include: · land for agriculture, houses and roads · jobs for local workers in road building, logging agriculture, extractive mining, building etc · The generation of income (often in valuable foreign currency) for the LEDC where the rainforest is located, when wood, minerals, and other resources are sold. · Scientific investigation into the rainforest plants may provide new food sources and medicines. These benefits, however, come at a heavy cost. Clearing rainforest threatens the survival of many plant and animal species and can lead to serious environmental degradation. Widespread deforestation damages the whole biosphere - the balance of living and non-living things on planet Earth - with serious long-term consequences for humans.
15. Positive impacts of human intervention · Improving transportation by building roads and airports provides jobs and benefits local people who use the roads. · Transportation improves access to raw materials like minerals and timber. Rainforest resources can be transported away and sold. · Profits from selling resources can be used to bring more development to a relatively poor country. For example, the tax a country raises from the sale of rainforest resources can be used to build schools and hospitals. · Selling raw materials , f or example tropical hardwoods such as ebony and mahogany, are valuable resources that can be sold for a good price abroad, bringing in foreign currency. People in MEDC's such as those in Europe and North America use hardwoods for garden furniture and hardwood flooring, for example. · Mineral deposits in the Amazon include bauxite (the main constituent of aluminium), iron ore, manganese, gold, silver and diamonds. Minerals can be sold with profits benefiting the LEDCs. · Infrastructure , hospitals and education can be improved from the money gained from selling natural resources. · Large-scale farming is another important way to bring money into a poor country, and to provide food for the country's growing population. Large-scale farming also employs local workers. · Small-scale farming is important for providing food for rainforest communities and landless poor of Brazil. Often these people have been displace from land in other parts of the country and have no other land to live on to produce the food they need to survive.
16. Problems of human intervention · Roads divide up parts of the rainforest and can cut off connections between different biotic and abiotic systems. For example, a road can stop monkeys such as the Golden Lion Tamarin from travelling to gather food and, in turn, distribute seeds to re-sow plants in the forest. · Land clearance for farming, transportation and mining can lead to deforestation . Hardwood trees take many years to grow, so can be difficult to replace. · Farming is estimated to be responsible for 25 percent of the Amazon forest being cleared. · Fertile soils that make farming possible are quickly washed away when the forest is cleared for farming, mining or transportation. · Loss of animal habitat occurs when trees are cut down and animals that live in them have to find somewhere else to live. Hence, deforestation can result in endangering animals and plant life, or even causing them to become extinct. · Profits from large-scale farming and selling resources often go back to MEDCs or large companies and don't benefit rainforest communities.
