PBL power-point shark week
This document outlines a project-based learning activity for 2nd grade students about sharks during shark week. The activity involves students researching two sharks of their choice from a list of 10 common sharks. For each shark, students will research and record its scientific name, length, lifespan, habitat, prey, and predators. Students will then create medals to honor each shark's service by drawing the medal image on the shark's pectoral fin, with different colored ribbons indicating danger levels to humans. The goal is for students to learn about various sharks through independent research using technology.

Ancient greece
Ancient Greece lasted from around 2000 BC to 146 BC. Greek society was highly stratified, with men having greater power and freedoms than women or slaves. Boys and girls were educated differently, with boys learning more subjects. Athens and Sparta also structured their societies in different ways, with Athens focusing on knowledge and Sparta on defense. The Greeks developed one of the earliest known alphabets and produced many great writers and philosophers. They introduced ideas like democracy, columns in architecture, and the Olympic Games that still influence modern society today.

Oil is collected from deep underground using large drills and pumps. It is found in places that were once underwater, where dead plants and animals were buried under layers of mud and sand over millions of years. Once extracted, oil is sent to refineries where it is cleaned and separated into useful parts like gasoline, diesel, and kerosene. However, oil is a finite resource that will eventually run out. It also harms the environment by contributing to issues like global warming, air pollution, and acid rain when burned as fuel. More sustainable energy sources could help reduce our dependence on oil.
Ancient china
Ancient China lasted over 5,000 years and made many important contributions. One was the Great Wall, built to protect dynasties over 1,700 years. Food depended on wealth, with poor people eating bland rice while rich ate meats. Leisure activities included music, games, and storytelling. Ancient Chinese inventions like the compass, gunpowder, paper, and printing are still important today.

This document summarizes an investigation into the relationship between height and jumping length. The hypothesis was that taller people would jump further than shorter people. Twenty people had their heights and jump lengths measured. The results showed that generally taller people jumped further, though some shorter people outjumped some taller people. On average, people jumped 20.4cm further than their height. The conclusion was that height influences jumping ability but other factors like individual jumping skill also affect results.
The finite times
We depend on oil for many products and energy, but it is a finite resource that comes from decomposed plants and animals trapped underground millions of years ago. Oil is collected through drilling and pumping from oil fields below the surface. While the oil industry is important for energy and jobs, it also causes environmental problems like global warming, acid rain, and pollution from spills. We could reduce our dependence on oil by using less energy and developing cleaner energy sources like solar.

Ancient greece report
Ancient Greece was a civilization between 800BCE and 146BCE located in what is now Europe. While the civilization ended thousands of years ago, it left many legacies still important today including the alphabet and Olympics. Education was important in ancient Greece though the content and accessibility differed between Athens, Sparta, and between boys and girls. Agriculture was challenging due to poor soil and climate but they grew olives, grapes, and wheat to eat along with fish and cheese. Society was highly stratified with democratic rule in Athens but only for adult men, and women and children had subordinate roles.
Ancient china
Ancient China lasted over 5,000 years, the longest of any civilization. Some key aspects of ancient Chinese civilization discussed are its unique architecture like the Great Wall, food like rice and noodles that depended on location in China, silk clothing that depended on wealth, and important inventions like the compass, paper, and gunpowder that originated in China and are still used today. The document provides details on these topics through several sections on architecture, food, clothing, and legacies of ancient China.
The finite times
Oil is a finite resource that comes from ancient plants and animals buried underground. It is extracted through drilling deep underground wells and pumping it to the surface. The oil is then sent to refineries where it is cleaned and separated into useful parts like gasoline. We are highly dependent on oil but it is not sustainable in the long run as we use it faster than it can be produced naturally. It also harms the environment when burned through air and water pollution. We need to reduce our oil usage through alternatives like recycling, bicycling, and using public transportation.

Coal is collected through surface or underground mining methods. Surface mining uses large machines to remove topsoil and rock layers to access coal deposits underneath. Underground mining involves using elevators to access deep tunnels where miners cut coal. Coal forms over hundreds of millions of years from decaying plant matter and is a non-renewable fossil fuel. Communities depend on the coal industry as it provides around 40% of the world's electricity and is used to make many other products. However, burning coal also harms the environment by releasing pollutants like carbon dioxide, sulfur dioxide, and nitrogen dioxide that cause issues like global warming, acid rain, and smog. Better management of the coal industry could involve using pollution control devices and transition

Wood comes from rainforests where loggers cut down trees using chainsaws or machinery. Lumber is wood from cut trees that is used to build houses, make furniture, and produce paper and pencils. The logging industry can damage forests by clear cutting, which removes all trees and damages animal habitats and the environment. A more sustainable alternative is strip logging, which removes trees in a way that mimics natural forest growth.
The finite times
The document discusses the wood industry and its impacts. It explains that wood comes from rainforests where loggers cut down trees using chainsaws or machines. The wood is then used to build houses, make furniture, and produce paper and pencils. However, logging large numbers of trees can damage rainforests and their ecosystems. Clear cutting whole areas can eliminate food and oxygen sources for animals and cause problems like flooding and global warming by reducing carbon dioxide absorption. A more sustainable alternative is strip logging, which mimics natural forest growth patterns.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

Length investigation
- 1. Length Investigation Aim: To investigate the relationship between a person’s arm length and head circumference. Hypothesis: I predict that head circumference is longer than arm length. Materials: measuring tapes pencil paper clipboard 20 people Method: 1. Draw a chart. 2. Write aim, hypothesis and materials. 3. Start measuring 20 students using tape measures. 4. Record the head circumference and the arm length of each student.
- 2. Results: Name Head (Cir.) Arm length Syakir 51cm 40cm Naina 52 41 Xella 53cm 39cm Alaa 63.5cm 43cm Yen yen 63.5cm 65.5cm Krishna 54cm 40cm Adam 54cm 51cm Nina 55cm 49cm Grace 48cm 43cm Ki joo 56cm 60cm Ms.yoshido 56cm 53cm Ms.odwyer 56cm 53cm Simon 56cm 47cm Takumi 56cm 49cm Genjiro 51cm 56cm Sang woo 53cm 58.3 Justus 60cm 61cm Hena 25cm 56cm Ki Jung 57cm 56cm Qiqi 53cm 47cm Average head circumference: 54cm Average arm length: 48cm
- 3. Conclusion: My hypothesis was incorrect. On average head circumference is 6cm longer then arm length. Discussion: It was difficult to predict that the head circumference and arm length was exact and it was not easy to measure all the people because they moved here and there. The results mean in the real world thatpeople will know about body proportions. I would like to learn more and more so I can get better at the investigations.
