3 COURSE CONTENT Air Pollution This module will allow students to understand the current composition of the atmosphere. They will be introduced to the common pollutants, their sources and effects. The students will be led though the importance of environmental monitoring with the use of abiotic and biotic sampling techniques. The students will develop fieldwork skills in data collection and planning of an investigation, including the interpretation of their own results and secondary data. They will gather primary data on indicator species (lichens) and gain an understanding of their distribution and mutual symbiotic relation. Throughout the module, the importance of biodiversity will be covered and linked into understanding populations, ecosystems and adaptations. The module will conclude with a discussion on what measures can be taken to reduce air pollution locally and nationally. CHOOSE ONE FROM: Limestone as a Resource Limestone is a commonly used building material and is a vital raw material in the production of glass, cement and concrete. Its products have historically been used to neutralise soil acidity and more recently to remove acidic gases produced by the burning of fossil fuels. Students will consider the formation of sedimentary rock and carry out simple experiments to model the key processes before making first hand observations of a landscape based on sedimentary rock and seeing evidence of fossils. They will follow an outdoor trail to see the effect of limestone quarrying and the ways that limestone can be used. They will make a photographic record of natural features formed by limestone erosion and the man-made products formed by limestone today. Climate Change The students will develop knowledge of how the atmosphere has evolved into the modern atmosphere that we live in today. They will also learn that it is difficult to know exactly about the early atmospheric conditions. There will be the opportunity for an investigation into the production of oxygen by aquatic vegetation, with students planning and collecting primary data. They will study how small changes in the atmosphere occur through human activity and how various gases trap heat from the sun and keep the Earth warm. Students will test carbon dioxide levels in the air and evaluate secondary data. The module will explore the story of carbon, one of the greenhouse gases, and how it can be measured in soils and the atmosphere, allowing the learner to better understand the carbon cycle. At the end of the module students will be able to discuss how models can be used to predict 'global warming', looking at the causes and consequences. They will understand the importance of environmental monitoring and possible methods of combating air pollution. Environmental Change Freshwater ecosystems, such as ponds and streams, are extremely important as habitats, supporting a wide variety of plants and animals. These freshwater ecosystems can become polluted through eutrophication. Students will use a scientific approach to design and implement an investigation of the health of a freshwater ecosystem. They will use a variety of equipment and techniques (including quadrats, nets and digital meters) to sample the communities of invertebrates, and other life, as well as the chemical and physical properties of water (including temperature, oxygen and nitrate concentrations). Using the Five Kingdoms system of classification, students will use keys and microscopes to identify organisms. The quality of the water will then be assessed by looking at the groups of aquatic invertebrates and using them as indicators to assess the level of water pollution and concentration of dissolved oxygen. Using microscopes and film clips during the day, students will investigate how different groups of organisms are adapted to the environmental conditions in the habitat, and how those adaptations allow them to survive. Students will have the opportunity to use ICT to graphically present and analyse the data. Primary and secondary data and images will be used to enable the students to draw conclusions and review their hypothesis about the environmental conditions and how these have affected the ecosystem. Students will evaluate the study, taking into account the limitations of methodology and evidence. Students will use information collected during the day and from secondary sources to make decisions about how the site could be managed to improve the health of the ecosystem and increase biodiversity.

4 Energy Efficiency and Building Audits How efficient is your home? This module will require students to test a variety of different materials and record primary data in regards to energy transfer. This will involve planning and carrying out an investigation by constructing a 'model house' and using sensors to measure the temperature with and without various types of insulators. The students will also use the 'model house' to test surfaces of different natures in relation to the absorbance of infra-red radiation and use the centre as an auditable building. During the module the students will use efficiency equations and diagrams of energy transfer to understand what is happening with the investigation. Potential ways to conserve energy and reduce energy consumption will be explored and limitations of the study will be discussed.

5 Environmental Change Identify how two named freshwater invertebrates are adapted to their environment and how they survive in varying conditions. Explain, giving examples, how changes in the environment affect the distribution of living organisms. Give an example of one biotic and one abiotic factors that a named organism is dependent on. Use a key to identify freshwater invertebrates and classify them into groups based on observable features. State how they could investigate how water pollution changes animal distribution. Use invertebrate animals as indicators of water pollution. Describe how abiotic factors can be measured. Describe how most ecosystems are reliant on the suns energy, and explain how this is transferred between trophic levels. Represent the energy at trophic levels in a freshwater ecosystem by creating a pyramid of numbers and of biomass. Understand the role of green plants as producers in capturing this energy and making it available to other organisms. Use data to draw food chains and webs and be able to identify producers, consumers and trophic levels. Use equipment and techniques to measure how physical factors (temp., oxygen and velocity) affect organisms. Use quadrats and nets, to investigate changes in the distribution of organisms within a freshwater habitat.
