The document discusses the water cycle and evaporation. Two-thirds of Earth's surface is covered in water as part of the hydrosphere. The water cycle is the continuous movement of water between the Earth's surface and atmosphere, changing between liquid and gas states. One part of the water cycle is evaporation, where heat causes liquid water to slowly change into a gas. An experiment is described to observe evaporation rates in different containers over time.

Presentation - Climate Change in Lower Mekong River
This document summarizes a student's research on the hydrological effects of climate change in the Mekong River. The research aims to investigate how global warming may impact runoff, potential evapotranspiration, sedimentation, and saline intrusion in the Lower Mekong Basin. The results suggest runoff will increase during the weak monsoon season from November to February due to higher winter temperatures and increased snowmelt. More fine sediments like clay and silt are also expected to move through the river system as a result of changes in discharge and temperature. However, accurately simulating sedimentation levels over time remains challenging due to lack of long-term data. Overall, climate change is anticipated to bring higher precipitation and discharge to
Edu653watercycle
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water evaporates from bodies of water and condenses into clouds, where it falls as precipitation and either runs off into other bodies of water or is absorbed by soil, starting the cycle again. Key processes in the water cycle include evaporation, condensation, precipitation, and runoff. The water cycle is essential to sustaining life and natural systems on Earth.

Climate change is occurring as a result of human activities that are changing the composition of the atmosphere and trapping more heat. Temperatures are rising in both the lower atmosphere and the oceans. This is leading to changes like rising sea levels, more extreme weather events, and shifts in precipitation patterns worldwide. According to the EPA and other scientific organizations, the evidence is clear that the climate is changing due to greenhouse gases from human activities like burning fossil fuels.
Climate change
Climate change refers to changes in global or regional climate patterns over long periods of time. The document provides evidence that the Earth's climate is changing, with the average global temperature rising 0.74°C over the last century and decreases in snow and ice extent. Some impacts of climate change include rising sea levels which diminish coastal lands, more frequent droughts that threaten food and water supplies, and increased intensity of tropical cyclones. The main cause of current climate change is human activity like greenhouse gas emissions from the burning of fossil fuels. If greenhouse gas emissions continue to increase unchecked, the climate impacts could mirror those of Venus with a runaway greenhouse effect.
Water and weather, by Ángel Manuel García Garrido
The document discusses the water cycle and the differences between weather and climate. It explains that the water cycle involves water evaporating from surfaces and condensing in the atmosphere to form clouds. Clouds play an important role, accumulating water droplets. Weather refers to current meteorological conditions in a specific area and time, while climate describes conditions over a large area for an extended period. Key processes that affect weather include the greenhouse effect, Earth's orbit, continental positions, and astronomical factors.
Climate change
Human activities such as burning fossil fuels and deforestation are now the dominant cause of increasing global temperatures in recent decades. To mitigate climate change, humans must minimize activities that impact the climate like CO2 emissions and instead follow the principles of reduce, reuse, and recycle in order to gradually allow the Earth to recover.
DAV PUBLIC SCHOOL - Climate change2
Climate change is a significant change in weather patterns over long periods of time that can be caused by both natural factors and human activities like greenhouse gas emissions. Scientists study climate change by analyzing physical evidence from various climate proxies like ice cores, sediment records, and historical documents to understand past climates and make projections about future climate change. Global warming due to increased greenhouse gases is causing sea levels to rise through thermal expansion of the oceans and melting of glaciers and ice sheets, threatening coastal areas with flooding and erosion.
Danielleconvection Current
Convection currents are movements of materials caused by temperature differences that occur in the Earth's atmosphere, oceans, lithosphere, and mantle. Large convection currents in the mantle are hypothesized to move continents by the constant rotation of hot and cold material, carrying tectonic plates. Convection currents also increase volcanism and contribute to the greenhouse effect.

Climate Change
Human activities like burning fossil fuels are releasing greenhouse gases and aerosols into the atmosphere, contributing to changes in the climate. Temperatures are rising in both the lower atmosphere and oceans, with minimum temperatures increasing faster than maximum temperatures. Various regions are experiencing changes like heavier precipitation in some areas and drought in others, along with sea level rise between 0.08 to 0.12 inches per year on average.
Climate change final
Climate change is disrupting the water cycle and jeopardizing water, food, and energy security. It is causing more frequent and intense droughts, heavy precipitation events, melting glaciers, and harmful algal blooms. Higher temperatures lead to increased evaporation and dry periods interspersed with heavy rainfall and flooding. Many glaciers are retreating and may disappear, reducing fresh water sources for dependent areas. Glacial melting is also expanding ocean volumes. Climate change has warmed waters and caused more common, severe algal blooms that damage ecosystems and threaten human and animal health.
Water Cycle Notes
The water cycle describes the continuous movement of water on, above, and below the Earth's surface, through different phases. Water evaporates from oceans and other bodies of water, rises into the atmosphere as vapor, condenses into clouds, and falls as precipitation onto land or surface water, completing the cycle. Water is transferred through processes like transpiration, runoff, and groundwater flow, and is stored in reservoirs like oceans, clouds, glaciers, lakes, and soil.
Global warming by IBRAHIM
Global warming is defined as an increase in the average temperature of the Earth's atmosphere due to an increase in greenhouse gases like carbon dioxide and methane. This is trapping more heat in the lower atmosphere and enhancing the greenhouse effect. The impacts of global warming include more extreme weather events like floods and droughts globally. For India, global warming is already resulting in rising temperatures, changing rainfall patterns, and more frequent extreme weather events that are damaging its economy and society. Key impacts include threats to health, water resources, agriculture, forests, and coastal areas.
3. ESS Systems and Feedback Notes
This document defines and describes systems and feedback. It notes that a system is a set of interconnected parts that form a whole. An open system can exchange matter, energy and information with its surroundings, while a closed system only exchanges energy. Feedback occurs when a system's output is used as input, and there are two types: negative feedback which stabilizes a system, and positive feedback which increases departures from the average. Examples of each type of feedback in climate systems are also provided.
DAV PUBLIC SCHOOL
Climate change refers to significant and long-lasting changes in weather patterns over decades or millions of years that may include changes in average conditions or more extreme weather events. It is caused by both natural factors like ocean circulation, solar radiation, tectonic and volcanic activities as well as human factors currently causing global warming and climate change through human alterations of the environment. On a broad scale, the balance between incoming and outgoing energy from the sun determines Earth's equilibrium temperature and climate.
Enso as an integrating
The document discusses the El Niño Southern Oscillation (ENSO) phenomenon as a key part of Earth's climate system. ENSO involves fluctuations between warm (El Niño) and cold (La Niña) conditions in the tropical Pacific Ocean and atmosphere. It occurs naturally every 2-7 years and shapes weather patterns globally. The document outlines the dynamics and physics behind ENSO cycles, their predictability, impacts on climate and ecosystems, and importance for understanding Earth's complex climate.
Water Notes
Water is composed of hydrogen and oxygen atoms bonded together as H2O molecules. The uneven distribution of charges within water molecules results in polarity, with the oxygen end slightly negative and hydrogen ends slightly positive. This allows opposing charges between molecules to form weak hydrogen bonds. Hydrogen bonding between water molecules absorbs heat energy and requires more energy to change water's state, especially during phase changes. It also results in water having a density of 1g/mL and being less dense as a solid than liquid. Hydrogen bonding and the resulting pockets account for these unique properties.
The water cycle
The water cycle describes how water is recycled on Earth through evaporation, condensation, precipitation, and collection. Water evaporates from bodies of water into water vapor due to heat from the sun, condenses into clouds as it rises and cools, precipitates as rain or snow back to Earth, and collects in rivers, lakes, and oceans to repeat the cycle.
Changing Climatic Factors
Climate describes typical weather conditions that prevail over extended periods in a region, while weather describes the hourly or daily conditions. Climate change is identified by long-term shifts in temperature, precipitation, winds and other indicators. The IPCC reported in 2007 that the climate is changing rapidly due to human activities like burning fossil fuels and deforestation being the primary factors. If aggressive action is not taken to reduce emissions, global temperatures could rise significantly by 2100 leading to major impacts.
Climate Change & Anthropogenic Impact On Water Resources
Human activities are clearly influencing the climate system and causing changes that are affecting water resources in several ways. According to the IPCC, over half of the increase in surface temperatures since the 1950s is due to human greenhouse gas emissions. As the climate continues to warm, precipitation patterns are projected to change in ways that will impact water availability and quality. Infrastructure like dams and reservoirs has altered water flows, and building more could help address issues like declining storage capacity but also risks impacts on environmental flows. Managing these tradeoffs between human and environmental water needs is an ongoing challenge.

1. Anticyclones form due to Rossby waves turning away from poles, dense cool air over continents in winter, and semi-permanent high pressure zones associated with global circulation like subtropical high pressure.
2. The heat equator, where the most solar energy is received, migrates between the Tropics of Cancer and Capricorn, and the zone of heaviest rainfall migrates with it.
3. Short term climate change operates over periods up to 1000 years, with El Nino being an example of very short term widespread disruption.
Climate Adaptation presentation - Boston Bar Assn. 5/6/13
This document discusses the context for addressing climate change impacts and adaptation, with a focus on issues related to water management. It notes that current climate models show that if emissions continue unchecked, over half of currently inhabited areas on Earth could become uninhabitable by the year 2300 due to extremely high wet-bulb temperatures. The document also summarizes models that project increased precipitation in the Northeast U.S. under climate change. It argues that adaptation approaches will need to address both excess water from storms as well as water shortages, and that risks are often underestimated due to natural human tendencies.
Sea level change_auckland_nzis_agm_oct10
The document discusses past, present, and future sea level change in the Auckland region of New Zealand. It summarizes that sea levels have fluctuated by about ±1m over the past 6,500 years. Auckland has a reliable tide gauge record showing current sea level rise of 1.5 mm/year with no evidence of acceleration. For 2100, projections estimate a global sea level rise of 18-59cm, with New Zealand planning for 50cm and assessing impacts of a potential 80cm rise based on current understanding.
How and why our climate is changing in the Hudson Valley
The document discusses climate change in the Hudson Valley region. It provides an overview of the Hudson River Estuary Program and its goals of clean water, resilient communities, and environmental education. It then covers the basics of climate science, explaining how climate differs from weather, factors that influence climate like the carbon cycle, and trends of rising temperatures and carbon dioxide levels. Finally, it outlines three climate hazards facing New York - increasing temperatures, rising sea levels, and changing precipitation patterns - and how these risks are already impacting the region through more frequent heat waves, short-term droughts, and flooding events.
Ocean currents
Surface ocean currents are caused by winds and extend hundreds of feet deep, circulating heat around the globe by carrying warm water away from the equator and cool water from the poles. Deep currents are driven by water density differences, while upwelling and downwelling movements cycle nutrients and oxygen between surface and deep waters, impacting marine life. Ocean currents influence global climate by redistributing heat worldwide via transport of warm and cold water, changing overlying air temperatures.
Review#13 water and the climate
The document discusses ocean currents and their impact on climate. It explains that warm surface currents originate near the equator and flow north, while cool surface currents originate in northern regions and flow south. The currents curve due to the Coriolis effect caused by the Earth's rotation. Ocean currents affect climate by moderating temperatures - warm currents bring warmer temperatures to cool climates, while cool currents have the opposite effect. Being near large bodies of water also helps regulate land temperatures.
2. ESS Earth's Spheres Notes
The document discusses Earth systems science which considers the interactions between Earth's four main spheres - the atmosphere, hydrosphere, geosphere, and biosphere - as well as human impacts. It defines each sphere, including that the hydrosphere is mostly salt water, the biosphere contains all living things, the lithosphere includes the mantle and core, and the atmosphere surrounds Earth and drives weather.
Watercycleday2
The document discusses the water cycle, which is the continuous movement of water between the Earth's surface and the atmosphere through different states of matter. Water evaporates from bodies of water into vapor, condenses into clouds, and precipitates as rain, hail or snow back to the Earth where it collects in bodies of water or soil.

The document discusses conventions of music videos and how the student's music video challenges some of those conventions. Some key points:
1) Typical music videos feature a star persona singing along with the lyrics and visuals telling the story of the song. The student's video features a powerful female character dominating two subservient male characters, challenging gender roles.
2) It explores the ideas of voyeurism and a struggle for power between "good" and "sexual" female characters. Intertextuality is represented through a recurring chess motif.
3) The video attempts to portray a theme of lust and self-destruction inspired by the song's lyrics through contrasting frames and minimal skin/opposite
Copy of airmasses
Air masses are large regions of air with similar properties that form over land or water surfaces and transport those conditions as they move. When different air masses collide, they form boundaries called fronts that often produce unstable weather. Satellites allow scientists to observe fronts and predict where weather may change quickly and dangerously, which is important for warning communities of potential severe conditions.
Copy of air masses review
There are two main types of air masses: continental polar and maritime tropical. A front is the boundary between two air masses of different temperatures. Cold fronts occur when cold air moves under warm air, bringing storms and drier conditions, while warm fronts happen as warm air moves over cold air, which can produce light precipitation or fog and warmer weather afterwards. Doppler radar maps can show the locations of cold and warm fronts.

The hydrologic cycle
The rates of movement of water and the quantities involved the cyclic processes are the major aspects involved in the hydrological sciences. There is an endless circulation of water among all the spheres of the earth. It is popularly known as the hydrologic cycle. It is necessary to learn about the hydrologic cycle, when we intend analyse the water resources of the region and the world.
Hydrologic Cycle
Water is essential for life and the hydrologic cycle distributes it around the planet. The cycle involves evaporation, transpiration, condensation, precipitation, collection as runoff or infiltration into groundwater, and storage in oceans, glaciers, and ice caps. Climate is influenced by the hydrologic cycle as warm air holds more water vapor and rising air cools, causing precipitation. Changes to the cycle, such as intensification due to climate change, can produce more extreme flooding and drought.
Hydrosphere Presentation
The hydrosphere refers to all the water on, under, and over the surface of the Earth, including oceans, seas, lakes, rivers, groundwater, and water in the atmosphere. It makes up about 0.023% of the Earth's total mass and covers around 70% of the Earth's surface. Water circulates through the hydrosphere in the water cycle, driven by energy from the sun that evaporates water from oceans, rivers, and lakes, where it rises into the atmosphere and condenses to form rain or snow and returns to Earth. The hydrosphere supports all life on Earth and its motion influences climate patterns globally.
Hydrosphere Presentation
The hydrosphere refers to all the water on, under, and over the surface of a planet, including the oceans, seas, lakes, rivers, ice caps, groundwater, and atmospheric water vapor. It makes up about 1% of Earth's total mass and covers about 70% of Earth's surface. The hydrosphere is always in motion through various processes of the water cycle, with water circulating between the oceans, atmosphere, and land through evaporation, condensation, precipitation, and runoff. Water pollution from human and natural sources threatens the hydrosphere by contaminating water bodies.
Bm
The document discusses various topics related to freshwater and saltwater habitats on Earth. It describes how fresh water makes up a small percentage of the total water on Earth, found in lakes, ponds, rivers and streams. It also discusses the water cycle, how water is constantly recycled from clouds to ground and back again. Finally, it touches on how human activities like pollution can negatively impact water quality in oceans.
hydrosphere and water pollution
The document discusses the hydrosphere, which refers to Earth's combined water resources. It describes how water exists in different states within the hydrosphere, including oceans, ice, vapor, and liquid water found in streams, lakes, soil and groundwater. It also summarizes the water cycle, in which water is stored and moves between different parts of the hydrosphere through processes like evaporation, condensation, precipitation and runoff.
Jc
Water is a chemical substance with the formula H2O that can exist as a solid, liquid, or gas. It is transparent and allows sunlight to reach aquatic plants and is the major component of cells. The water cycle is driven by the sun and involves evaporation, condensation, precipitation, runoff, infiltration, groundwater discharge and springs. Ocean surface topography varies in a similar way to land topography and influences ocean currents, heat transport, and sea level changes. Tides are caused by gravitational forces from the moon and sun, resulting in two high and two low tides daily in most coastal areas. Human pollution and development are deteriorating ocean ecosystems.

The document discusses water resources and the hydrological cycle. It begins by defining the hydrological cycle and discussing its major processes. It then explains that water exists in three forms - solid, liquid, and gas - due to climatic variations. Water is essential for life but must be preserved and used carefully. The document further analyzes the hydrological cycle and how water circulates between the oceans, atmosphere, and land in vapor, liquid, and solid forms. It also notes that while water is abundant globally, freshwater availability does not always meet demand.
Fresh water
The document discusses the water cycle and distribution of water on Earth. Most (97%) of Earth's water is saltwater found in oceans. The remaining 3% is freshwater, with 76% bound up as ice in glaciers and ice sheets and less than 1% available for human use. Water is constantly circulated through the water cycle, driven by energy from the sun. In the cycle, water evaporates from oceans and land into the atmosphere, forms clouds, and falls back to the Earth's surface as precipitation like rain or snow.
The Hydrologic Cycle
The document provides an overview of the hydrologic cycle. It begins with an introduction explaining that water circulates continuously between different spheres of the Earth. It then discusses the major components of the hydrologic cycle, including precipitation, evaporation, transpiration, runoff, infiltration, and others. Finally, it explains concepts like condensation and how precipitation forms from water vapor in the atmosphere. The overall document serves to describe the world's water circulation and the relationships between different elements of the hydrologic cycle.

The document summarizes key concepts about water, including its physical and chemical properties, the water cycle, humidity, phases of water, and more. It discusses how water vapor condenses to form clouds and rain, which then flows into rivers and oceans. The unique properties of water make it essential for life on Earth.
Our earth is mostly water
- The Earth has just the right conditions to support liquid water, which covers 70% of the planet's surface and is essential for life. Water is constantly circulating between the oceans, atmosphere, and land in the water cycle.
- In the water cycle, energy from the sun evaporates water from oceans, lakes, and other bodies of water into water vapor in the atmosphere. Water vapor condenses into clouds and falls as precipitation. Precipitation returns to bodies of water, soaking into the ground as groundwater, or running over land as surface water back into oceans, restarting the cycle.
Power point presentation

Water cycle review
The water cycle involves the continuous movement of water on, above, and below the Earth's surface. It includes four main parts: evaporation where the sun turns water into vapor, condensation where water vapor in the air condenses into liquid water forming clouds, precipitation where clouds become too full and water falls as rain, snow, or hail, and collection where precipitation is collected in oceans, lakes, rivers, soil, or underground.
Severestorms
Thunderstorms are common storms that produce lightning and thunder through heating of the air. They form in three stages - air rises to form clouds, moisture falls as rain or hail when clouds can no longer hold it, and static electricity builds from air moving in opposite directions causing lightning. Thunderstorms usually form ahead of cold fronts in warm air and can sometimes spawn tornadoes in areas where warm, moist air meets cold, dry air masses like the Great Plains and Mississippi Valley.
Reviewandseverestorms
An orbit is the path of a planet as it travels around a star. A planet's orbit is its trajectory through space as it revolves around the star at the center of its planetary system. Orbits allow planets to travel through space in a regular and predictable pattern around their parent star.
Meteorology energy absorption
Heat energy is absorbed by objects in a manner similar to how sponges absorb water, with the heat entering the object and warming it over time as more heat is absorbed. This process of heat absorption can be seen when cooking a Thanksgiving turkey in the oven, as the turkey initially cool and raw but slowly heats up and cooks through as it absorbs more heat. Different objects absorb heat at varying rates, with dark colors generally absorbing more heat than light colors due to dark colors absorbing more light.
Hurricanes
Hurricanes are large, swirling storms with very low pressure and winds between 75-200 mph that form over warm ocean waters. They rotate counterclockwise around an inner eye with light winds. When hurricanes make landfall, they cause significant damage to buildings, trees, and cars from high winds and storm surges that push water inland, especially in shallow coastal areas. The Atlantic and Eastern Pacific hurricane seasons run from June-November, though most storms occur in the fall. Hurricanes are named from rotating lists to identify them.
Earthrevolution
Earth revolves around the sun once every 365 days. A revolution is the time it takes an object to complete one orbit, while rotation refers to an object spinning on its axis. The length of a year is different for each planet depending on how far it is from the sun, with closer planets like Mercury having shorter years than Earth and more distant planets like Neptune having longer years.
Airmasses
Air masses are large regions of air with similar properties that form over land or water surfaces and transport those conditions as they move. When different air masses collide, they form boundaries called fronts that often produce unstable weather. Satellites allow scientists to observe fronts and predict where weather may change quickly, which is important for warning communities of potential dangerous conditions.

Earthlayers rocks
The document discusses the different layers of the Earth, including the crust, mantle, inner core and outer core. It then provides analogies comparing the Earth's structure to an apple. Finally, it outlines the three main types of rocks - igneous, sedimentary, and metamorphic - and provides a brief description of how each type is formed through melting, layering of materials, and changes caused by pressure and heat respectively.
Volcano ppt
The document discusses four volcanoes: Cinder Cone Volcano, Mount St. Helens which is a composite volcano and erupted in 1980, Kilauea volcano in Hawaii which is a shield volcano and currently erupting.
Industrialization and immigration
The document discusses how industrialization changed manufacturing and immigration patterns in the United States. It describes how the Industrial Revolution led to the rise of factories, which attracted many immigrants to urban areas for work. Immigrants often faced difficult working conditions in crowded cities and had little money upon arrival. The first stop for many immigrants between 1890-1914 was Ellis Island, where they underwent health screenings before entering the country.
Homestead act ppt
The Homestead Act was passed in 1862 to encourage settlement of the Great Plains by offering citizens 160 acres of government land if they improved the land by building a home and planting crops within 5 years. While the requirements seemed easy, many settlers lacked farming experience and the land was dry, making farming difficult. Less than half of the 2 million people who claimed land under the Homestead Act lived there long enough to own it. Pioneers built homes out of sod blocks when wood was scarce.
Trailof tears ppt
The document summarizes the Trail of Tears, which was the forced relocation of the Cherokee Nation in the 1830s. The Cherokee were removed from their ancestral lands in Georgia and other southeastern states following the Indian Removal Act of 1830. Over 4,000 Cherokee died due to the poor conditions during their march west to Indian Territory (now Oklahoma). Some Cherokee escaped the removal by hiding out in the Appalachian Mountains of Georgia and North Carolina.
Regions southeast-growingseasonandcoal
The document summarizes key aspects of agriculture and industry in the Southeast region of the United States. It notes that the long growing season allows for the profitable growth of crops like peanuts, oranges, soybeans, rice, and cotton. It also discusses how coal was an important resource historically, though mining it was dangerous work until labor unions advocated for improved safety conditions and regulations in the late 19th century.
Autumn in the northeast
Autumn is a popular season in the Northeast due to the beautiful changing colors of the broadleaf trees. As temperatures fall and daylight decreases in September and October, the leaves stop producing green pigment and take on vibrant red, orange, and yellow hues. These colors last only a few weeks before the leaves die and fall from the trees. The Northeast has many forests due to its proximity to the ocean and high levels of precipitation, providing trees with the water they need to thrive. Tourism increases during autumn as city residents travel to rural areas to view the colorful foliage.
Southeast mississippi
1. The document describes the Mississippi River, the longest river in the United States which flows north to south and empties into the Gulf of Mexico.
2. It discusses how the river grows broader and deeper as it flows south, fed by tributaries like the Missouri and Ohio Rivers.
3. The final paragraphs explain how the Mississippi River delta deposits rich soil as it empties into the sea, forming wetlands in Louisiana that help control floods and provide habitat.
Slavery beginnings
Slavery in the U.S. Africans were forced onto crowded slave ships for the brutal Middle Passage journey across the Atlantic to the Americas, where over 20% died from diseases and cruel conditions. Survivors were sold into slavery and forced to work long hours on southern plantations growing cotton and tobacco, often living in small dirty cabins. They were punished harshly if they disobeyed or tried to escape, and slavery led to the American Civil War.
Lincolnbday
Abraham Lincoln turns 200 years old and delivered the famous Gettysburg Address 87 years after the Declaration of Independence in 1776 to help reunite the nation after the Civil War battle at Gettysburg by calling for equality and honoring the soldiers who died there.
Leading up to civil war
The document summarizes the key events leading up to the start of the American Civil War. It explains that the Northern states had growing cities, factories and railroads while the Southern states relied on plantation agriculture and slavery. Southern states increasingly feared that the North would pass laws to end slavery and damage the Southern economy. After Abraham Lincoln was elected as president in 1860 on a platform to stop the expansion of slavery, several Southern states seceded from the Union to form the Confederate States of America. The Civil War began when Confederate forces fired upon and forced the surrender of Union troops at Fort Sumter in South Carolina in April 1861.
Introto c wbattlesandemancipationproc
The document summarizes key events of the American Civil War, including battles such as Bull Run, Antietam, and Gettysburg. It discusses Abraham Lincoln issuing the Emancipation Proclamation in 1863 to emancipate slaves in Confederate states, and his delivery of the Gettysburg Address that same year at the dedication of a national cemetery at the Gettysburg battlefield. The war concluded in 1865 with Confederate General Robert E. Lee surrendering to Union General Ulysses S. Grant at Appomattox Court House.

A Strategic Approach: GenAI in Education
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.
