40 mark SDME assessment in the form of a Powerpoint with associated resources
Background: Why does Holderness suffer from severe coastal erosion? What are the advantages and disadvantages of halting erosion?
Options: Why has hard engineering used to defend Hornsea? Why is soft engineering gaining popularity?
Decision: Do nothing, retreat the line, hold the line or advance the line
Powerpoint covering spit formation, using Spurn as a Case Study
Starter: simple (revision) sorting activity to sequence weathering, erosion, transportation and deposition
Main activities:YouTube videos and a mystery activity to find out how Spurn Head has formed. Pupils use mystery clues to complete and annotate a base map of southern Holderness and the Humber Estuary. Mini-plenary to recognise associated landforms in aerial photos
Second part uses bespoke, high tech (:D) series of diagrams (an animation if you click your mouse quickly enough!) which show why the point of the spit hooks (the role of secondary winds and wave refraction)
Final part gets pupils to sketch and annotate diagrams of Marram and Glasswort to show how dune and salt marsh plants and habitats are interdependent. Differentiated question... 1-3: Describe how salt marshes and sand dunes are held in position by plants 4-6: Why are salt marsh and sand dune environments natural sea defences? 7-9: What could happen to the Humber Estuary if the vegetation at Spurn Head is not protected?
Plenary: the 250 year cycle of spit formation and destruction at the mouth of the Humber Estuary
Powerpoint looking at erosion and transportation along Holderness
Starter: the properties of powerful waves, including fetch
Main activities: map work to measure the fetch from Holderness to various coasts of the North Sea. Then radar diagrams are introduced, using a wind rose as an example followed by the pupils constructing a radar to show dominant wave patterns. Then the link between the UK's SW prevailing wind and how it causes NNE dominant waves. Differentiated question... 1-3: What makes a sea wave powerful? 4-6: Explain why North Sea waves can be powerful and damaging
7-9: Refer to data which suggests that Holderness is threatened by powerful waves
Second part gets pupils to draw and label diagrams to compare the features of constructive and destructive waves. They are then asked to assess photos of Holderness to decide which type of wave is affecting that coastline.
Third part looks at the properties of boulder clay and why that soft geology is a problem. Differentiated question: 1-3: Why are the caravan owners worried about the erosion of the cliffs at Hornsea? 4-6: Explain why erosion of the boulder clay is a problem for Holderness
7-9: Explain why the erosion of boulder clay is an economic problem for Holderness businesses
Plenary: pupils are asked to show how they think a typical wave moves, then are shown an animation that describes the circular motion of real wave patterns
Powerpoint covering headlands and bays along the destructive Holderness coast
Starter: use maps to locate Flamborough Head
Main activities: sketch bird's eye view diagrams showing before and after erosion has affected a discordant coastline. Followed by a differentiated question: 1-3: How do headlands and bays form? 4-6: What role have chalk and boulder clay played in the formation of Flamborough Head?
7-9: What is wave refraction and how has it affected the Flamborough landscape?
Second part gets pupils to annotate a diagram to show the sequence of cave-arch-stack formation using a series of mixed-up pieces of info (so can be done as a card sort or a mystery). Class then feeds back verbally by responding to a series of images and questions
Third part: pupils work together to find advantages and disadvantages of headlands and bays using clues from a large scale OS map
Plenary: pupils recap learning by describing and explaining features seen in a photo of the chalk at Flamborough
Powerpoint introducing Holderness as a Case Study for coastal processes
Starter: use maps to locate Holderness
Main activities: comparison of the properties of chalk (through a memorisation activity and differentiated question) and boulder clay (pupils learn one fact then swap info to answer... What is boulder clay? Where did it come from? How did it get to Yorkshire? What has it got to do with our lesson about coastal landscapes?
Second part gets pupils to draw a sketch map of Holderness then to annotate features that could be lost if erosion continues (using info researched from the internet)
Differentiated question: 1-3: Why are there weaknesses found in chalk? 4-6: Why is Flamborough Head prone to erosion? 7-9: What are the geological reasons for the faults found in the chalk at Flamborough Head?
Plenary shows the wide range of origins for sediment found along Holderness
Powerpoint looking at the formation of meanders and oxbow lakes in the Middle Stage of the River Tay
Starter: sketch and match definitions of four types of transportation
Main activities: step-by-step slides taking pupils through the formation of meanders and oxbow lakes. Each pupil is given a fact about the processes involved. Sketches are made of meanders in different stages then pupils use their clues to teach the rest of the class about what is happening so they can label their diagrams. Also includes some photo analysis of river valleys in the real world
Second part gets pupils to draw and label a cross-section of an asymmetrical meander using width, depth and velocity data
Differentiated question: 1-3: Describe how a river channel changes from one side of a meander to the other; 4-6: Explain how a meander can become an oxbow lake over time; 7-9: Explain how meanders and oxbow lakes can be both useful and cause problems for humans
Plenary: pupils recap learning by describing and explaining features seen in a series of satellite photos showing a meander turning into an oxbow over time
Powerpoint looking at the skill of constructing cross-sections from contour lines
Starter: recap of the formation of v-shaped valleys (including video link)
Main activities: step-by-step slides taking pupils through how to construct a labelled cross-section of the Upper Stage of the River Tay
Analysis of a photo of the Middle Stage of the River Tay to compare human and physical features and then to compare those with a photo of the Upper Stage
Pupils then construct their own cross-section of the Middle Stage
Differentiated questions comparing the cross-sections of the three river stages (the Upper Stage is already completed for them)
Plenary: pupils have to look for clues in photos of a completely different river (the Wisla in Poland) to decide in which stages they were taken
Powerpoint looking at the Upper Stage of the River Tay
Starter: Pupils use maps to discuss the links between the location of Britain’s rivers, patterns of landscape and patterns of precipitation
Main activities: video link introducing the Upper Stage of the Tay
Carousel of activities about erosion types (memorisation), forestry (exam-style questions), features of upland valleys (SPAG), hill sheep (exam-style question), waterfalls (use mystery clues to annotate sequence of diagrams) and HEP (exam-style questions)
Second lesson used for class discussions to recap learning using slides and videos
Class debate on the sustainability of forestry, sheep farming and HEP in the Tay Valley
Differentiated questions about the features found in the Upper Stage
