Coasts
Look at the picture below. What is it? How are people using it? What geographical features does it show?
In this unit......you will be learning about coastal landforms, how we use coasts, and how we can manage them sustainably. You will also go on a field trip to a local site to examine the coast there and look at their management strategies.
|
Key Questions1. What are coasts and how do we use them?
2. What kinds of coastal landforms are there and how are they formed? 3. How are coasts affected by natural and human events and interactions? 4. Why and how do we try to manage coasts? 5. How can we manage the coastline in a sustainable way? |
NOTE: Not all activities are here as some will only be carried out in the classroom.

Activities:
1. Waves (Homework - before class): Read pages 131 and 123 in your Jacaranda textbook. Use this link to find out more information on waves. The video below on waves will also be helpful. Use this information to make brief notes on: i) how waves form, ii) the factors that affect wave formation and iii) the characteristics and effects of constructive and destructive waves. Be prepared to apply these concepts in class to demonstrate your understanding.
2. Waves (Classwork): You will need to draw and label a diagram explaining how waves form. You must also answer Q 1 and 3 on page 131 and Q1 and 5 on page 123.
3. Longshore Drift and Erosive Processes: Longshore drift is the way material is carried along the shore. You will find an excellent explanation and animation here. You should also read pages 122-123 in your Jacaranda textbook. For erosive processes, look at this site, which outlines the 6 main processes, and this site, which has animations for 4 of them. Once you have done this, you should complete Q3 and 7 on page 123. You should also complete the erosive processes worksheet below - name and explain how each process works.
4. Learning about Coastal Landforms: Your teacher will discuss this in class but you should also read the information on the links here, as there are some great animations to show you how some coastal landforms are created. This slideshare and this scribd document both give you a good overview. These pages are a bit more basic but the first focuses specifically on depositional landforms while the second focuses on erosional landforms. You will also find pages 120-121 and 124-129 in your textbook very helpful.
5. Download the 'Coastal Landforms Task' below. This is a 'kml' file that is used with Google Earth - you should make sure that you have Google Earth installed. Double-click on the kml file to load it up in Google Earth. You should click on each step of the task to 'travel' to the landform or region and answer the questions attached to it. You can then save this as a kml file that you can send to your teacher to demonstrate your understanding of coastal landforms. Use the information and links from Part 3 (above) on learning about coastal landforms to help you complete this task.

Week 2
Learning Objectives:
- You should be able to name the ways that we use and interact with coasts.
- You should be able to discuss the negative and positive impacts we have on coasts, and how these are linked to the way that we use them.
- You should be able to define the terms 'hard engineering' and 'soft engineering', and discuss how different types of these (e.g. groynes, gabions, sea walls, beach replenishment, etc) are used to manage coasts.
- You should be able to carry out the following fieldwork skills: note-taking, field-sketching, taking and annotating photographs, and observing the environment.
Activities:
1. Land Use: You should carry out a Think, Pair, Share using the 'Coasts' images set. What uses can you see in the images? What others can you think of given your prior knowledge of coasts? You should contribute your ideas and knowledge to create a class MindMap (using Inspiration) or Prezi.
2.
3. Management Techniques: In groups of 3 or 4, you should research a specific soft or hard management technique. Please do this thoroughly, as you will be the expert in this field. You should produce a short PowerPoint saying what it is and how it works. Also: what are the advantages and disadvantages? Where do they work the best? You must also include a picture of this management technique in action. Your picture should have a caption that explains where and how the technique is being used.

What are the differences between hard and soft management techniques? Use a Venn diagram to illustrate these.
Week 3
Learning Objectives:
- You should be able to use the relevant fieldwork skills you learned last week and apply them while evaluating a local coastal management issue.
- You should be able to write up a field report based on information and data collected while on this field trip. This includes writing an introduction and background that explains the issue/s, discussing your methods of data collection, and displaying your data using geographical presentation conventions (think: clearly, titled/labelled, and BOLTSSNA where applicable). You should include i) a regional map (with BOLTSSNA) that identifies the study area, and ii) a local map that shows a lot of detail. You must also draw a birds-eye sketch of the beach based on your observations. You should identify and label, with evidence e.g. photos, the different ways that people are using the coast in this area.

Fieldwork Gallery:
If you need any photos to support your field report, you can access them here (click on the bold, underlined text). Remember, you need to mention the source of your photos in your bibliography. Issues Graphic Organiser:
You can use this to map your thinking. Make sure that you write it up properly though - this is just to help you organise your thoughts and should not be handed in as part of your field report. ![]()

Week 4
Learning Objectives:
- You must continue adding to your fieldwork with these elements: You should add in a table with a list of issues (problems) that human activity in the area has caused. You must also include techniques that are currently being used to manage these issues, plus some of your own. You must explain how human activity has caused these issues, and how the management techniques will be helpful in dealing with these problems. You should also evaluate the issues and management techniques, and make recommendations for how they could improve.
Week 5
Learning Objectives:
- You will apply the knowledge that you have acquired thus far to evaluate an international case study, and to determine if the management techniques being used in this case are appropriate and if not, what could be done instead.
- You will also review and consolidate your knowledge by actively participating in a variety of activities.
