Accidents are unexpected events or happening at home, school, on the road or at work which can lead to injuries or death. It can cause pain, sorrow, discomfort or deformation of the body. Some accidents are caused by mistakes, stubbornness, carelessness or disobedience. The accident at home is called domestic accident. TYPES OF ACCIDENT 1) BURNS: These are caused by hot objects like hot iron. Burns could be caused through fire incidents. 2) BITES: These are caused by animals such as snakes, dogs, insects etc. Some insect’s bites may lead to itching of the spot and its surroundings. This may later lead to a serious discomfort. 3) BRUISES: These are marks on the skin which results when one falls of hit by a person in a fight. This action causes the swelling of the skin. 4) SCALDS: Scalds are caused by hot water, hot oil or acid if it mistakenly touches or pours on the body. 5) CUTS: These are caused by sharp objects such as knife, blades, scissors. 6) ROAD ACCIDENTS: These are caused by Reckless driving, bad roads(potholes). 7) AIR AND SEA ACCIDENTS: These are mainly caused by poor weather and engine failure. It can lead to materials and human beings lost. 8) RAIL ACCIDENTS: These are caused by bad railways and careless crossing by motorists. THE FOLLOWING ARE THE WAYS OF PREVENTING ACCIDENTS. 1. Do not play near an open fire or flame. 2. Do not run up the staircase but walk smartly. 3. Do not dare a strange dog. 4. Do not play with sharp objects likes blades, knives and scissors. 5. Do not play with harmful insects. 6. Avoid rough plays to prevent bruises and wounds and other forms of accidents. 7. Remove all objects that can cause a fall on the way. 8. Wear dry rubber slippers before operating an electrical appliance like Television, refrigerator and pressing iron. 9. Always obey your parents’ instructions. 10. Always keep the floor clean at all time.

A Prairie Guard Dog I am on a journey. My trip is to a prairie. It is in the outdoor world called nature. Many animals live in a prairie habitat. This place has what prairie dogs need to survive. A prairie has a lot of grasses but few trees. Without places to hide, a prairie can be dangerous for some animals. Good Morning! It is early in the morning. First, I see a prairie dog. I name him Pete. He peeks his head out of his burrow underground. He looks around. Then Pete calls loudly to his family, "Yip!" He lets them know it is safe to come out. Soon four prairie dogs come out. Pete is the guard and he is restless. He cannot rest because he is always looking around for danger. This allows the other prairie dogs to safely munch on grasses and seeds. They can also groom each other or work on their burrow. A Scare Oh no! Pete spies a large badger! When he sees it, he gives a loud bark, "Yap! Yap!" His family recognizes the warning. Some hide in tall grasses, and some jump into the burrow. The badger runs at Pete, but the watchful guard is able to escape into the burrow. I am glad he is able to get away from danger. After a few minutes, Pete peeks his head out again and he is back on the job. Break Time The sun gets higher, and it is hot now. The prairie dogs slip into their deep burrow where it is cooler. Even Pete goes in. Tunnels, like hallways, lead to different areas. There is a sleeping room. There is a room used like a bathroom. The prairie dogs cover up roots and seeds in one room. Later, they eat the buried food there. Second Shift I keep watching the burrow. Finally, the sun begins to set and a different prairie dog peeks its head out. I name him Gary. Pete must be off duty. "Yip," Gary calls. The other prairie dogs come back out. The prairie dogs eat and play until the moon is high in the sky. Then they go to sleep in their burrows. I wonder if Pete will be back on duty. I will see in the morning.

Animal Rights and Diet Success Criteria I can explain key terms which describe the type of diets people have I can explain the advantages and disadvantages of different types of diet Animal Rights and Diet Match up the terms with the meaning Term Meaning Omnivore - eats fish but no other type of meat Vegetarian - eats most types of meat and vegetables Pescetarian - doesn’t eat any products that come from animals Vegan - doesn’t eat meat but will eat dairy products like milk Place the different diets on a spectrum All meat No animal products at all Vegetarian Vegan Omnivore Pescetarian Omnivore Omnivore Most people in the UK are omnivores Match the countries with the amount of meat eaten per person per year Country Meat per person per year India 9.9 kg USA 4.4 kg Bangladesh 120 kg UK 111.5kg Nepal 84.2 kg Australia 4 kg Numeracy How much meat is consumed in the UK per year? (Amount of meat eaten X the UK population) 2. How much meat is consumed in Bangladesh per year? (Amount of meat eaten X the Bangladesh population) Country Meat per person per year USA 120 kg Australia 111.5kg UK 84.2 kg Nepal 9.9 kg India 4.4 kg Bangladesh 4 kg UK – 64 million Bangladesh – 165 million http://www.telegraph.co.uk/travel/maps-and-graphics/world-according-to-meat-consumption/ 7 Why do people eat meat? Discuss Tradition (their family has always done it) Culture (celebrations) Taste Convenience Nutrients such as B12, protein and iron Consumption of meat is rising across developing countries because higher incomes generally mean more meat eating. Pescetarian "Yeah, I'm a vegetarian." "But that looks like fish you're eating." "Oh yeah, I eat fish.“ An estimated 5% - 6% of people in the UK are pescetarians. How many people is this? Approx. 3.6 million Calculation – 66,000,000 /100 x 5.5 = 3,630,000 9 Which group is cuter? Animals Fish 10 People often don’t feel as much love for fish as they do for fluffy, cute mammals. The may think fish don’t feel pain. They may be fussy. They think fish isn’t meat. Not farmed as much as mammals; can be wild. To get nutrients they wouldn’t get from just vegetables and grains. (Omega 3 is in plants but in higher concentrations in oily fish) Why are people pescetarians? https://www.vegsoc.org/sslpage.aspx?pid=753 http://articles.mercola.com/omega-3.aspx Fish – In a perfect world, fish can provide you all the omega-3s you need. Unfortunately, the vast majority of the fish supply is now heavily tainted with industrial toxins and pollutants, such as heavy metals which include mercury, lead, arsenic, and cadmium, PCBs, and radioactive poisons. These toxins make eating fish no longer recommended. 11 Vegetarianism Vegetarians will not eat any meat or product that comes from the slaughter of animals e.g. gelatine. About 3% of the UK population are vegetarian. How many people is this? 1.9 million 12 Why are people vegetarian? They don’t like the idea that animals are killed so they can eat Health reasons Don’t like meat Brought up vegetarian Environmental reasons Religious reasons (e.g. some Buddhist, Hindus) Watch the following clip twice. The second time, write down the fact which surprises you the most. https://www.youtube.com/watch?v=VW6wfpHFdaI The World Health Organization has classified processed meats – including ham, salami, sausages and hot dogs – as a Group 1 carcinogen (same as smoking/alcohol) which means that there is strong evidence that processed meats cause cancer. Red meat, such as beef, lamb and pork has been classified as a 'probable' cause of cancer. 13 Veganism Not just a diet Around 1% of the population of UK are vegans. A vegan is described by the Vegan Society as “a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of humans, animals and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals” Why are people vegan? Why are people vegan?

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep. Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water, As it smoothes rough, sharp rock surfaces, weathering is often the first step in the production of soils. Tiny bits of weathered minerals mix with plants, animal remains, fungi, bacteria, and other organisms. A single type of weathered rock often produces infertile soil, while weathered materials from a collection of rocks is richer in mineral diversity and contributes to more fertile soil. Soils types associated with a mixture of weathered rock include glacial till, loess, and alluvial sediments. Weathering is often divided into the processes of mechanical weathering and chemical weathering. Biological weathering, in whichliving or once-living organisms contribute to weathering, can be a part of both processes. Mechanical Weathering Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble. Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. If temperatures drop low enough, the water will freeze. When water freezes, it expands. The ice then works as a wedge. It slowly widens the cracks and splits the rock. When ice melts, liquid water performs the act of erosion by carrying away the tiny rock fragments lost in the split. This specific process (the freeze-thaw cycle) is called frost weathering or cryofracturing. Figure 4.3 Frost Wedging Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again. the structure of the rock weakens. Over time, it crumbles. Rocky desert landscapes are particularly vulnerable to thermal stress. The outer layer of desert rocks undergo repeated stress as the temperature changes from day Eventually, Lo outer night. layersflake off in thin sheets, a process called exfoliation. Exfoliation contributes to the formation of bornhardts, one of the most dramatic features in landscapes formed by weathering and erosion. Bornhardts are tall, domed, isolated rocks often found areas. in tropical Sugarloaf Mountain, an iconic landmark in Rio de Janeiro, Brazil, is bornhardt. a Salt also works to weather rock in a process called haloclasty. Saltwater sometimes gets into the cracks and pores of rock. If the saltwater evaporates, salt crystals are left behind. As the crystals grow, they put pressure on the rock, slowly breaking it apart. Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks. Even small plants, such as mosses, can enlarge tiny cracks as they grow. Animals that tunnel underground, such as moles and prairie dogs, also work to break apart rock and soil. Other animals dig and trample rock aboveground, causing rock to slowly crumble. Chemical Weathering Chemical weathering changes the molecular structure of rocks and soil.For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock. Carbonic acid is especially effective at dissolving limestone. When carbonic acid seeps through limestone underground, it can open up huge cracks or hollow out vast networks of caves. Carlsbad Caverns National Park, in the U.S. state of New Mexico, includes more than 119 limestone caves created by weathering and erosion. The largest is called the Big Room.. With an area of about 33,210 square meters (357,469 square feet), the Big Room is the size of six football fields. Another type of chemical weathering works on rocks that contain iron. These rocks turn to rust in a process called oxidation. Rust is a compound created by the interaction of oxygen and iron in the presence of water. As rust expands, it weakens rock and helps break it apart. Another familiar form of chemical weathering is hydrolysis. In the process of hydrolysis, a new solution (a mixture of two or more substances) is formed as chemicals in rock interact with water. In many rocks, for example, sodium minerals interact with water to form a saltwater solution. Hydration and hydrolysis contribute to flared slopes, another dramatic example of a landscape formed by weathering and erosion. Flared slopes are sometimes nicknamed "wave rocks." Their c-shape is largely concave rock formations a result of subsurface weathering, in which hydration and hydrolysis wear away rocks beneath the landscape's surfaceWeathering and People Weathering is a natural process, but human activities can speed it up. For example, certain kinds of air pollution increase the rate of weathering Burning coal, natural and petroleum releases chemicals such as nitrogen oxide and gas, sulfur dioxide into the atmosphere. When these chemicals combine with sunlight and moisture, they change into acids. They then fall back to Earth as acid rain. Acid rain rapidly weathers limestone, marble, and other kinds of stone. The effects of acid rain can often be seen on gravestones, making names and other inscriptions impossible to read. Acid rain has also damaged many historic buildings and monuments. For example, at 71 meters (233 feet) tall, the Leshan Giant Buddha at Mount Emei, China is the world's largest statue of the Buddha. It was carved 1,300 years ago and sat unharmed for centuries. An innovative drainage system mitigates the natural process of erosion But in recent years, acid rain has turned the statue's nose black and made some of its hair crumble and fall.

Write simple RCQ for this story: Finding Cal September 25 Dear Diary, It took Dad a long time to decide. He finally made up his mind. Dad came to my room tonight. He said I could get a dog! But it has to be a small or medium-sized dog. We will go to the animal shelter tomorrow. September 26 Dear Diary, Wow! There are so many different dogs at the shelter. There are big and little dogs. Some have soft fur and some have wiry hair. Dad and I walked to one dog's cage. The tag said the dog's name was Cal. One quick glance at the cute dog, and I knew he was for me. Dad said, "Look, Jake! Look at how Cal stares at you." It was true! His eyes were wide open. He was looking right at me. We put Cal on a leash and took him to a fenced yard. Cal smiled and stared at me. Cal wanted to play. In minutes he learned the proper, or correct, way to sit. He could walk on a leash nicely, too. I patted him on the head, and he licked my hand. Dad said, "I see a real connection between you and Cal." I agreed. We already had a good relationship. Soon we were on our way home. Cal was nervous so I tried to make him feel better. I scratched his ears, and he liked it. October 10 Dear Diary, It has been a while since I have written. Cal has learned many new tricks like how to roll over. I have learned from Cal, too. Cal walks with Dad and me to school every day. Each night, Dad reads me a story. Cal lies next to me. I would not trade him for any other dog. I will keep him because our friendship is very special. Finding Cal was worth the wait!

Helper Dogs Some people can’t see. They get help from special dogs called guide dogs. These dogs are calm, smart, and easy to train. It takes two years to train a guide dog. First, the dog lives with a family for one year. Then a trainer teaches the dogs many things. He learns how to cross the street. He learns to stop at a red signal. He learns how to lead a person through busy streets. Guide dogs are great helpers.
