1 Year 12 Subject Gg Topic Coasts Week 1-6 Coverage / key questions Resources Homework Lesson Learning outcomes Teacher Student Assessment 1 Explain what the littoral zone is Describe the various parts of the littoral zone Understand the key elements of inputs and outputs into the coastal system Introduction to topic Which units in Year 12 Why the coast is important to study Definition of LZ/ card sort activity on parts of the LZ/ discussion on inputs and outputs of the coastal system Exam question on the coastal system 2 Understand that there are many processes at work along our That sediment movement and geology play an important role in the landforms created at the coast Be able to describe some of the processes involved Lead discussion Ppt examples Possible exam questions they may ask about this topic Discussions on how physical factors play a key role in the development of landscapes Examples of high and low energy Sediment supplies through offshore, onshore and estuarine environments could be discussed with an understanding in the formation of deltas which could be built on later Thorough review of how important geology is to coastline development. Geological maps of places like the Jurassic coast could be used to explain the ideas of concordant and discordant (idea of wave refraction might be introduced). Assess types of with a focus on concordant/ discordant

2 in the creation of landscapes 3 Explain how Geology is integral to certain landscape development Be able to interpret satellite imagery of Describe different types of coastal morphology 4 Describe the formation and succession of sand dunes variety of temporal elements involved and their importance in shaping our coasts 5 Explain the importance of Geology in the erosion of Show pictures of different Lead discussion on factors that create different c'lines Leading to creation of sand dunes Teacher can explain the different factors such as low energy, increased inputs. What makes some coasts more erodible than others? What dictates the shape? Teacher to explain the concepts of hard explaining the formation of both Haff and Dalmatian type, introduction to the ideas of submergent and emergent style coasts and the reasons for these. Introduction to erosion rates and the formation of cliff profiles by satellite pictures and students being able to classify these into the into groups of such as emergent or submergent What physical processes go in to making depositional such as Salt marsh, Estuarine, Sand Dunes Complete activity on all the different factors plus UK examples Students decide themselves on how sand dunes are created or what features they have Explanation of constructive and destructive waves with exemplification through Ppt. Diagrams and the processes involved and how they influence beach morphology such as berms and other minor beach landforms Baseline test to be done by 12th September Introduce the ideas of rock type and rock hardness by showing from different lithologies. Discussion on permeable and impermeable rocks and the impact this will have on a Key term revision or glossary test to end session/ picture analysis of difficult to classify Mind map one example showing physical processes, different factors, types of waves and features Swap and groups improve Essay question

3 importance of differential erosion in determining the shape and formation of our coasts. v soft and how these can be relative to each other (e.g. Limestone is hard next to glacial till but soft next to granite) coastline. Draw and annotate drawing simple but effective Geological sketches and field sketches of landscapes annotated well. 6 Understand the main types of erosional processes and the landforms they help to create importance of wave type, size and lithology in creating distinctive coastal landforms Teacher to go through the main erosional processes and what they do and the landscapes they create. Teacher to draw out and go through the processes of erosion on headlands The class can be split into groups and have to act out Coastal Kung Fu (This can be googled and found on YouTube) Students to draw and annotate blank diagrams Different pictures can be used to show theoretical headlands and less obvious ones and top level students could try to interpret why they look like they do and do not follow the theoretical drawing (Examples could be taken from Flamborough Head. Jurassic coast [Durdle Door] Animations can be googled for this as well). Create revision style cards for each process under timed conditions - committing to short term memory 7 Understand how depositional features create a variety of landscapes Describe the process of longshore drift impacts that longshore drift can What do students believe dynamic equilibrium is on Animations on sediment transportation Essential to evaluate the impacts Dynamic Equilibrium within sediment cells. If some are struggling it can be shown via drawing a small bay and using arbitrary figures such as if 10 goes in 10 must come out (Sediment) if only 9 comes out then sediment is being trapped in the bay and not in equilibrium and similarly if 11 comes out then the beach is eroding, Animations on sediment transportation write notes/ use teacher created descriptions to understand and explain the processes What possible exam questions 12, 15 or 20 mark options Set teacher created exam question

4 have on the coastline Explain the concept of Dynamic Equilibrium 8 Describe and explain the various types of weathering and assess how they impact on coastal recession importance of sub aerial processes in influencing rates of coastal retreat. 9 Write down the issues created by mass movement at the coast (These are numerous and can be put into Social, economic and environmental categories) Teacher explains the different types of weathering and how these processes work, A teacher led discussion on the last ice age and its areal extent. (There is a popular misconception that it covered the entire planet. Explain the main issues created by changes in water Ppt. To show how longshore drift works in reality The landforms of deposition can be discussed using images and explanations as well as well documented examples from around UK and global Introduced to erosional processes via: /Why-buy-house-blind-auction- Torquay-landslide-takes-154k-home-it.html picture more important than text. A range of on printouts; explain what influences sediment production and rates of retreat have on this. Holderness used as main example; smaller scale examples to include Happisburgh and St. Bees. Must know the causes of mass movement along a specific stretch of coastline W rite down the issues created by mass movement at the coast (These are numerous and can be put into Social, economic and environmental categories) Baseline test to be done before the 12th September How the change in sea levels and the ice on the land would impact upon sea levels; describe the differences to between last ice age and now Explanation of different types of sea level change and the processes involved. Understanding of relict/ raised beaches and rias and fjords for both submergent and emergent through images, textbook pages. Exemplification by aerial/ google earth pictures. Begin the write up process for evaluate the contribution of sub aerial and erosional process on the impact of coastal retreat (20) Review of material so far - short quiz based on knowledge

5 Management of has lead to unforeseen issues Coastal retreat is influenced by a variety of factors beyond our control We can calculate rates of retreat via different methods. 11 Clearly explain what a storm surge stores and how sea levels fell significantly allowing not only for new coastline creation but also land to appear above sea level and people to migrate across land (e.g. English Chanel). Provides pictures of the previous ice extent Teacher led discussion on different types of physical reasons the are receding but them implications for humans. Teacher could approach this in terms of discussion and the roles each factor plays at different coasts through photographic evidence. Discussion on case studies There are several early classifications of Johnson (1919), Valentin (1952), Inman and Nordstram (1971) Students researching these for homework and have a short written evaluation of each in terms of validity and whether it helps in our understanding of coastal morphology ready to discuss Discussion of coastal classifications What causes coastal erosion and why areas might be under threat. Shown different such as from Maldives the Nile Delta and California and asked to consider whether these are receding or advancing. What if anything can be done to stop this from happening? (Can students name different management types and link them to the right kind of defence (Hold the line advance the line do nothing, management retreat.) Techniques to be assessed in depth and who is to blame for issues such as stability of coastline (Nile) Geomorphological factors play a key role in coastal recession. MAY TAKE 3 LESSONS Students are given case studies of Thailand Mangrove removal, The Maldives and the Pett 6 and 8 mark questions on coastal erosion and different management types Teacher created Research how Mangroves in Thailand impact the coastline

6 is and the different ways in which they are created Understand that the impacts of storm surges differ That global sea level rise can have devastating impacts for some people 12 Climate change will cause a variety of impacts on our That there are different techniques to use to help reduce the impacts Some areas of the world face an uncertain future Losses from coastal flooding and retreat can have devastating impacts on communities There are different Provide material of human/ physical problems on the coast Give sheet on some human and physical causes Lead on revision of key learning fro previous two lessons Examples of the impacts of climate change Present students with different scenarios in terms of low to high economically valuable land and low to high levels of population density as well as the Levels in the UK (Or the storm surge of 2013) Analyse these possibly done via provided material. Look at the human and physical causes of the problems. Assess these and the impacts of management or lack of management of these coasts and what are the implications for the future. Should be asked to consider the human factors in terms of level of development. For instance the removal of Mangroves in Thailand for shrimp farming has economic gains, whilst water diversion on the Nile helps to develop farming. Further extension should be to consider the future for these areas. Draw up a table of two storm surges e.g. UK 2013 and Philippines or Thailand with causes impacts, for Social, Economic, Environmental) 5 reasons for coastal retreat; 4 reasons for storm surges; 3 types of depositional coastline explained; 2 types of sea level rise explained; 1 Explanation for raised beaches Impacts climate change will have on the coast via a mind map, links could then be found between the different parts and examples linked in. Explanation of mitigation and adaptation List the impacts of the flooding under Social, Economic and Environmental. Further analysis of case study for Holderness or North Norfolk coastline and the implications for the wider area could be pursued via political issues they may create for the region (Lack of Is management the best way forward or are we just prolonging the inevitable? Go through key learning; folder check;assessment points

7 ways to measure losses Local losses can lead to political problems 13 Students should be able to assess the impacts of climate change and storm surges on of countries at different levels of development Understand that environmental refugees will rise if sea level rise continues 14 There are many different ways of managing our That management of coasts can impacts on physical systems, that hard and soft approaches have a variety of positives importance of biodiversity The idea here is to develop an awareness of lack of insurance, jobs and livelihood, well being etc. Provide list of facts that show the differences between the communities Teacher introduces idea of environmental refugees Photo interpretation of a range of approaches to management to assess environmental impact. Provide case studies and lead discussion on evaluation of investment, unemployment, for instance Jaywick in Norfolk) Understanding the reasons why economic costs of coastal flooding in developed world is higher but the relative costs in the developing world can be significantly worse. Students to separate into groups representing developing and developed communities discuss and generate ideas for a debate on who is the worst effected, based on the impacts and what is important to them. Each group could be given a list of facts that they should consider such as management in place, building safety etc. Students may well consider coming up with their own. These lists might differ between countries Case studies on environmental refugees Tuvalu Island in the Pacific Ocean Match a list of processes and how to manage each process Building on case study information students are to do a cost benefit analysis on different techniques and to look at problems (e.g. terminal Groyne effect) created by different players The use of soft engineering has its positives and negatives using case studies try to see when it is best to use them and how beneficial are they as part of an SMP. The UK has many small scale tuvalu-disappear-beneath-the-sea /?no-ist Analyse who should be responsible for climate change disasters/ effects Either summary of advantages and disadvantages or hardv soft engineering

8 and negatives attached to them. 15 Sustainable management of our coasts relies on our understanding of our Piecemeal approaches to coastal management is being replaced by ICZMs 16 What are four distinct approaches to coastal management Why are decisionn difficult Who are the winners and losers? Do policies rely on cost and benefits and EIAs? What does it mean to look at the coastline holistically. management types Clear understanding of ICZM How can coastal management be made more sustainable Examples of coastal management causing conflict Is mitigation or adaptation the best way forward? The conflicts that appear should be highlighted and why certain areas benefit at the cost of others and the implications this has for a stretch of coastline examples that could be used here: Management of the Sefton Sand dunes (North West) Portobello Beach (Scotland) List the ways in which coastline management could try to be sustainable but management is going to rely on hard choices and can create conflicts. Examples here can come from those on specification as well as local ones. Students to be introduced to the idea of Intercoastal Zone Management (ICZM) and how these work within sediment cells (Often this is an area students struggle with the concept and its relation to SMPs Development of concept through use of case studies such as Holderness ICZM and the subsequent SMP and stable Bays Discussion/ debate on what needs doing and how chosen protection impacts on others down the coast. Agreements have to be made about what is best and these generally take the form of CBA and EIA. Write notes on different players within the context of specific case study End of topic Teacher made exam question on coastal management sustainability Write up one case study which has caused conflict and the opinions of different groups
