Solar energy, the cycling of matter, and gravity sustain life on Earth. Ecosystems survive through energy flow and matter recycling. Water's unique properties, including its ability to dissolve compounds and change state, drive key Earth processes like the water and carbon cycles. The nitrogen cycle involves nitrogen fixation by bacteria, assimilation by plants, ammonification, nitrification, and denitrification, returning nitrogen to the atmosphere in a natural cyclic process.
All of the presentations that i have uploaded are made by me for school projects from 9-12 grade.For most of them you actually need to have learned something to recite and what you see on the presentations are just hints.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

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

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.

1. What Sustains Life on Earth?
• Solar energy, the
cycling of matter,
and gravity
sustain the
earth’s life.
2. Two Secrets of Survival: Energy Flow
and Matter Recycle
• An ecosystem
survives by a
combination of
energy flow and
matter recycling.
3. Water’ Unique Properties
• There are strong forces of attraction between
molecules of water.
• Water exists as a liquid over a wide
temperature range.
• Liquid water changes temperature slowly.
• It takes a large amount of energy for water to
evaporate.
• Liquid water can dissolve a variety of
compounds.
• Water expands when it freezes.
4. • Water moves through the biotic and abiotic factors in the
environment
• Ways water can move:
– Precipitation
• water moves from the atmosphere to the land in the
form of snow, rain, sleet and hail.
• During evaporation and transpiration (evaporation
from plants and through skin) water cools and
condenses, precipitation forms
• About 91% falls into oceans. The rest falls on land to
replenish the fresh water supply
– Evaporation
• Water moves from the land to the atmosphere
• Ground Water – when precipitation seeps into the
ground and becomes part of the water table
Runoff
Water that flows on top of the ground

6. The Carbon Cycle
• All living things have carbon in them
• All carbon that is on earth has been here since the
earth was formed
• Photosynthesis – carbon gets taken out of the air and
used by producers to make food
• Respiration- carbon gets put back into the air by
animals when they exhale
• Decomposition – breakdown of dead materials by
bacteria and fungi
• Combustion – carbon in fossil fuels is released while
burning
9. The Nitrogen Cycle
• 78% of the earth’s atmosphere is nitrogen
• Organisms cannot use nitrogen directly from
atmosphere
• Nitrogen fixation- when bacteria in the soil change
atmospheric nitrogen gas into usable nitrogen
• Lightening can also fix nitrogen
• Denitrification-different bacteria change usable
nitrogen into atmospheric nitrogen gas
10. Nitrogen Cycle
• natural cyclic
process in the
course of which
atmospheric
nitrogen enters the
soil and becomes
part of living
organisms
12. Nitrogen Fixation
• nitrogen gas is converted into
inorganic nitrogen compounds. It is mostly
(90 percent) accomplished by free-living,
nitrogen-fixing bacteria.
13. Nitrogen-Fixing Bacteria
• symbiotic bacteria living on the roots of
plants (mostly legumes and alders)
• cyanobacteria (formerly known as blue-
green algae)
• archaebacteria (also known as archaea) in
deep-sea hydrothermal vents
14. Nitrogen Fixation by Lightning
• The high energies provided by lightning
and cosmic radiation serve to combine
atmospheric nitrogen and oxygen into
nitrates, which are carried to the Earth’s
surface in precipitation.
16. Nitrogen Assimilation
• are assimilation of nitrates and ammonia
resulting from nitrogen fixation into the
specific tissue compounds of algae and
higher plants. Animals then ingest these
algae and plants, converting them into their
own body compounds.
20. Nitrification
• a process carried out by nitrifying bacteria,
transforms soil ammonia into nitrates,
which plants can incorporate into their
own tissues.
