Glossopdale Community College Science Department Course Title: BTEC extended certificate in Applied Science Assessors Name : Assessment Title Affecting the environment Learners Name Time needed Start date 3 weeks Finish by Chemistry and our Earth Scenario You work for the council in its planning and environment department. The council applying for an award its environmental awareness. You have been asked to prepare a presentation to support the application. Assessment Evidence, Notes of your research for the poster to short PowerPoint presentation giving a balanced view of the affects of human and natural activities of the earth and its environment. These will come from carrying out the tasks set in the assignment, but you may want to add extra information you find. A poster or short PowerPoint presentation. Whichever is used it must provide evidence that the affects of human and natural activities of the earth and its environment are described, explained and evaluated Achieved Grading Criteria The grading criteria that this assignment relates to: P6 Identify the human activities that are affecting the Earth and its environment M6 Describe how the choices humans make have an effect on the Earth and its environment D4 Explain possible solutions to the effect humans have on the Earth and its environment. P7 Identify natural factors that have changed the surface and atmosphere of the Earth. M7 Describe the ways that natural factors have changed the surface and atmosphere of the Earth over millions of years. Assessor’s Comments/Feedback Internal Verifier’s comments Learner’s Signature Human and Natural activities Task 1 The earth’s ‘environment’ consists of land, water and air. (a) Identify the human activities affects have on the earth’s environment: (b) Identify some natural activities that change the Earths surface and atmosphere. P6 P7 Task 2 As Humans we have choices on how to use the resources on our planet. Describe what affects these have include positives and negatives for these situations. obtaining starting materials from the sea, land and air, e.g. coal, natural gas, oil, metal ores, salt, nitrogen, oxygen burning fossil fuels to provide societies with energy processing and manufacturing chemicals. CFC Land and sea contamination Task 3 M6. Part 1 Use your knowledge of tectonic plates to describe how the land has changed over millions of years. This should include (a) Formation of mountains (b) Earthquakes (c) Position and fertility of Islands Part 2 Describe how Natural Factors the atmosphere has changed. (a) Carbon content (b) Sources of nitrogen (c) Oxygen content M7 Task 4 Sustainable development Find out about these issues: waste disposal, recycling and reuse fossil fuels versus nuclear fission fuels; biomass; future fuels, e.g. hydrogen, ethanol, nuclear fusion greenhouse gases acid rain Damaging effects of chemicals such as DDT, CFCs. From the information you have gathered here and in task 2, write a balanced account of the effects of human and natural activities on the earth and its environment AND HOW THEY CAN BE AVOIDED. D4.
