Lesson Plan - Essay Example It is taken from the website of the Department of Education, Employment and Workplace Relations, Australia. It presents a model lesson plan for a state school in Australia. A lesson plan is a detailed description of the course instructed by the teacher to the class. Lesson plans are developed by the teacher on a daily, weekly or monthly basis. The lesson plan critique presented in this paper evaluates the course on the basis of its objectives, activities and assessment. Students will start learning the value of water and natural resources at an early age, which is beneficial for them and society. The objectives of the lesson plan include focusing on the values of responsibility, care, compassion, respect and sustainability. The key learning areas here include art, society & environment and science. The first activity includes thinking about water in a session. Students can  think and generate questions on the topic such as: What is water? Where does it come from? How it is stored and used? Is there enough availability of water for the humanity? Questions like these can certainly generate a lot of curiosity among children and help them in knowing its value and appropriate use. The thinking session will be followed by questions and queries discussed by students among themselves. They will be asked to write their ideas on the board. This activity asks students to identify ways of using water resources. Several pictures and short movies are shown to students and questions are asked based on water usage, responsible usage and conservation of water. Students are to visit the school campus and ask to note down the ways of water usage on a sheet of paper. Students will come to know the overall water usage from different sources such as drink taps, kitchen, gardening water, staff rooms and toilets. After this, they will categorize all what they have seen inside the school campus. The curriculum will move ahead with two activities covered in the

Negative Impacts of Oil Exploration on Nigerias Biodiversity Essay

Negative Impacts of Oil Exploration on Nigerias Biodiversity - Essay Example It is Africa’s largest wetland, which consists of flat and low lying swamps that are a result of sediment deposition beautifully arranged in a terrain. The area has four different ecological zones which include coastal barrier islands, mangrove swamp forests, fresh water swamps and lowland rainforests. Due to this diverse ecosystem, the delta is one of the world’s most concentrated regions in biodiversity. Not only does it have the potential of supporting abundant fauna and flora, it has the potential of sustaining agricultural production. The freshness of the water gives it the ability of harbouring fresh water fish as well as a water catchment area for domestic consumption. However, the biodiversity has been destroyed by oil exploration activities around the area, and is proving to be a threat to the environment of the place. This paper will look at the various negative impacts of oil exploration in Nigeria has had on the biodiversity. Statistically according to Kadaf a (2012, p. 18) Nigeria ranks at first position in the world with flare gas, constituting 46% of Africa’s total flared gas per tonne of oil produced. This accounted for 19.79 per cent of the total global figure in the 1990s. During the period between 1970 and 1979, the average rate of gas flaring in Nigeria stood at 97%. In the period between 1980 and 1989 saw 97% of gas being flared while the years between 1990 and 1999 saw a total of 97% of gas be flared in Nigeria. Most of the gas extracted in the delta is immediately flared into the environment at a rate of 70 million/m3 per day. Gas flaring is the biggest contributor of air pollution in the Niger delta (Edino, et a., 2010, p. 67). Gas flaring emits greenhouse gasses into the atmosphere which include methane and carbon dioxide, the major contributors of global warming. Environmentalists argue that air pollutants are highly concentrated in the Niger Delta than in the rest parts of Nigeria as a result of oil extraction. Gas flare sites produce a lot of heat, which is as high as 1,600 Celsius, making it a major contributor of thermo pollution. Moreover, areas as far as 43.8 metres away from the sites experience temperatures of close to 400 Celsius, which negatively affect the vegetation and animal life and affects ecological equilibrium (Emoyan, 2008, p. 30-34). Global warming is potentially dangerous to the sea level of the low laying coastal areas as it potentially raises the sea level. Evidence of environmental degradation of the delta include inundation on large scale, increased coastal erosion, modification of habitats as wildlife are redistributed in the area, increased intensity of high rainfall events which is associated with increased run off. Soil erosion is a major occurrence as flash floods are common in the region while ocean storm surges have been a frequent occurrence (Kadafa, p. 2012, p. 20). Combined, these effects on the environment potentially jeopardize the survival of communities l iving in the region. Gas flares have been responsible for rain water and ground water acidification, research has indicated. Evidence shows that the Niger delta has high levels concentration of volatile oxides of carbon, nitrogen and sulphur oxide which exceeding normal standards of federal environmental protection agency. Due to the increased pollution levels, water from shallowly dug wells has indicated the presence of low pH levels, a cause of acid rain. The effects of acid rain cannot be underestimated. Not only does it corrode roofing sheets of houses and commercial buildings, it also damages vegetation as well as contaminate pools, lakes and rivers which are home for fish and other marine life (Akpomuvie, 2011, p. 206). Oil mining in the Niger delta
