The document discusses diffusion and related transport processes. It defines diffusion as the passive movement of molecules from an area of high concentration to low concentration. Osmosis is defined as the diffusion of water molecules across a partially permeable membrane, from low to high solute concentration. Active transport is the movement of molecules against a concentration gradient, requiring energy. Key examples discussed include gas exchange in the lungs, nutrient absorption in the small intestine and placenta, and ion regulation in cells.

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.

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.

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

Teacher notes
This true-or-false activity could be used as a plenary or revision exercise on diffusion, or at the start of the lesson to gauge students’ existing knowledge of the subject matter. Coloured traffic light cards (red = false, yellow = don’t know, green = true) could be used to make this a whole-class exercise.
Teacher notes
This zoom activity could be used to lead students on a step-by-step journey down to the level of the alveoli. It could also be used to review prior knowledge. Students could be asked to say where alveoli are found and then additional questions could be posed to move them up or down the hierarchy towards a more precise understanding of their location.
Teacher notes
This four-stage animation shows how oxygen and carbon dioxide are exchanged in the alveoli. Suitable prompts could include:
Start: What is special about the shape of the alveoli and their position to the capillary blood supply?
Stage 1: Why is the blood arriving at the lungs deoxygenated?
Stage 2: What colour is haemoglobin?
Stage 3: Which other substances are produced during respiration?
Stage 4: Approximately what percentage (approx). of exhaled air is carbon dioxide? (4%)

Teacher notes
This illustration contains several discussion points relating to movement in and out of cells, including:
Rats escaping from prisonThis section of the illustration represents diffusion. The rats are running from the prison through the gaps in the fence (representing a partially-permeable membrane). The rats are running from an area of high concentration (inside the prison) to an area of low concentration (outside the prison), i.e. along a concentration gradient.
Prison guard watering wilted flowers
This section of the illustration represents osmosis. The water being sprayed from the hosepipe represents water particles moving from an area of high concentration to an area of low concentration (the parched soil), i.e. along a concentration gradient.
Objects being passed through the wire fenceThis section of the illustration represents active transport. The bags represent cellular substances and the fence represents a partially-permeable membrane. The bags are being passed from an area of low concentration (outside the prison) to high concentration (inside the prison), i.e. against a concentration gradient.
Teacher notes
This two-stage animation shows how substances are transported across the cell membrane. Suitable prompts could include:
Start: What kind of molecules are transported by active transport? (e.g. sodium and potassium in muscle cells)
Stage 1: Which process provides the energy for active transport? (respiration)
