Coasts

Key Questions Knowledge, Understanding, Skills, Content Activities Resources
·         What are coasts?

·         What will this unit cover?

 

·         to know what Geographers refer to as ‘the coast’

·         to understand the wider aims and goals of the unit

·         brainstorm ‘the coast’ – students to compare ideas in pairs, then write their ideas on the board; come up with a class definition; then compare with a dictionary definition

·         explain the wider aims and goals of the unit – students to read through OHTs

·         true or false – read out a set of facts; for each one, students must answer by holding up their true/false card

·         aims and goals OHTs

·         true/false cards, quiz

·         What is weathering?

 

·         to have a definition of weathering and to understand what it means

·         to be able to identify different types of weathering

·         starter: recap true/false quiz to see how much students have retained OR use the same questions for student ‘hotseating’ (one student sits at the front and answers the questions set by the class)

·         explain that the world’s surface is made up of different landscapes – identify some from photos around the room – and that this is due to weathering and erosion; define the term weathering, students to copy from OHT

·         read through handout on types of weathering

·         complete questions on OHT in books

·         prep: ‘What is Weathering’ worksheet from Connections Teachers Pack (p.27-9)

·         extension: sorting the evidence worksheet from Connections Teachers Pack (p.30-2)

·         quiz questions

·         weathering definition

·         weathering handout

·         questions on OHT

·         ‘What is Weathering’ worksheet

·         sorting the evidence worksheet

 

·         What is erosion? ·         to have a definition of erosion and to understand what it means

·         to be able to identify different types of weathering

·         explain what erosion does and read through handout on types of erosion; link erosion into sequence with transportation and deposition

·         complete erosion questions on OHT in books

·         complete weathering and erosion worksheet (p. 35 old Connections Teacher’s Pack)

·         plenary: question loop cards – each student has a card with a question and a different answer: choose a student at random to read out his/her question and wait for the student with the correct answer to realise; he/she then asks his/her question

·         erosion handout

·         questions on OHT

·         weathering and erosion worksheet

·         loop cards

·         What are coasts? ·         to recap definitions of coasts

 

·         recap definitions of ‘the coast’

 

·         definition of coasts on OHT
·         What causes waves?

·         What causes tides?

·         to understand that waves are caused by wind dragging on the surface of the water

·         to be able to define what fetch is

·         to have an understanding of what causes tides and what the effects are on coastal areas

·         brainstorm ‘waves’ and what causes them

·         explain what ‘swash’ and ‘backwash’ are – students to copy definitions from OHT

·         explain the difference between constructive and destructive waves

·         brainstorm the concept of ‘tides’

·         explain how tides form (as the moon travels around the Earth it attracts the sea and pulls it upwards. High tides occur about every 12½ hours with low tides in between; the drop in sea level from high to low is called the tidal range – in the Bristol Channel this can be up to 15m); show photos to help explain

·         complete questions from p.7 in Geog.2

·         definitions on OHT

·         tidal photos

·         questions from Geog.2

·         How do waves shape the coastline? ·         to understand how erosion, deposition and transportation affect and therefore shape the coastline

·         to know that there are four main types of erosion

·         optional starter: complete question loop cards again to recap first part of the unit

·         introduce the idea that waves erode the coastline, they then carry the material elsewhere where it is then deposited

·         read through erosion section on handout to show the different types of erosion

·         draw longshore drift onto the board for students to copy for the transportation section

·         read through section on deposition

·         complete questions

·         question loop cards

·         handout with questions

·         What landforms are created by the waves? ·         to be able to link photos with sketch diagrams of coastal features

·         to understand how waves create different landforms

·         talk through sketch diagram of a section of coast and talk through each information box

·         students to read through sketches and descriptions of the three stages of how wave-cut platforms form and how caves, arches and stacks form; discuss; using worksheet, students to draw out sketches

·         complete questions

·         prep: complete storyboard of how Old Harry was formed, as if written by Old Harry himself

·         photo/sketch/labels

·         photocopy of section of coast taken from p.10-11 Geog.2

·         worksheet

·         questions

·         storyboard

·         What is the coast like along the Dorset coast? ·         to apply knowledge to a section of UK coastline ·         starter: true/false quiz on coastal processes and landforms

·         Picture board reveal exercise: ask pupils to choose a number (1-9) and this will reveal one square. They have 5 seconds to look and guess, then click HOME. They need to keep in mind what they’ve seen as they only get one section of the picture at a time. Once someone gets the correct answer, click home then click on the INFORMATION action button to reveal the actual picture. Students could also be asked to talk about the section they see, or name 3 things they can identify etc… (Bay; Beach; Beach with groynes; Durdle Door; Old Harry; Seychelles)

·         read through questions on the Dorset coast

·         students to work through questions

·         true/false quiz

·         PP

·         map of Dorset and questions p.12-13 Geog.2

·         Why does landuse in coastal areas need to be managed? ·         to appreciate that the different users of coasts will inevitably cause conflict and how this can be managed and reduced as much as possible ·         brainstorm users of the coast – lower ability may use photo on p.14 of Geog.2 to help

·         construct a conflict grid and establish who conflicts with whom and to what extent

·         using the OS map of the Dorset coastline from last lesson, pupils to identify the activities that take place in this coastal area – lower ability to use four figure grid references, higher ability to use six figure grid references

·         photo p. 14

·         OS map of Dorset coastline

·         Where is erosion a problem in the UK?

·         What can be done about the threat of erosion?

·         to appreciate that there are some parts of the UK that are severely under threat from coastal erosion

·         to know what happened in Mappleton

·         to complete a simplified geological map of the UK

·         students to make their own copy of the simplified geological map of the UK which also identifies areas where coastal erosion is a problem

·         explain a bit about coastal erosion and the very real threat it poses to some areas – highlight that over 20 villages have been lost to the sea since Roman times off the Yorkshire coast

·         read through six ways in which coastal erosion can be stopped – using OHT, students to complete their own worksheet, adding in their own diagrams

·         read through worksheet on Mappleton and complete questions

·         read through Coastal Erosion Mystery cards; students to decide why Jim & Betty are having problems getting house insurance; write up in full for prep

·         UK geological map and blank maps

·         OHT with coastal defence cartoons

·         Coastal erosion mystery cards

·         blank worksheet

·         Mappleton information and questions worksheet

·         What are the problems in defending the coast against erosion? ·         to understand that preventative action can be taken against coastal erosion, although it is not necessarily always the most practical solution

 

·         read through information sheet about the problems with fighting erosion, who decides which areas are defended and what the overall strategy is ·         information sheet
