What is a glacier anyway? |

Before you begin learning today, you need to first reflect on what you already know about the geographical details in the booklet. On page 2 there is a space to colour code your understanding at the start of this topic. Rate what you understand or don't understand by colouring the outer circle sections - for example, if you feel like you really don't understand climate change - then you would colour in that wedge red.
Starter Go to page 3 in your workbook. At the top it will give you an idea of what you will accomplish in today's lesson. For your starter, complete the Do It Now task first. |
Task 1
Match the key terms to their definitions provided in the workbook at the bottom of page 3. Stuck? Have a look here to help. Task 2 Read the New Knowledge information on page 4 of your booklet. Then, look at the figure 1 graph provided below. Use this to answer 'What do you think this graph is showing'? Task 3 Click on the video link at the top of page 5 in your booklet. As you watch, fill in the table provided below the link in the booklet. |
Task 4
Complete the reflection tasks on page 6 in the workbook. Stuck? Here is an example of what you may want to write: The first cause that I would like to explain is orbital changes. This is when the Earth's orbit changes over time, becoming more elliptical, which has an impact on the amount of solar radiation that enters the Earth's atmosphere. For example, when the Earth is further away in the ellipse, winters become more intense as there is less radiation entering the atmosphere. This could lead to glaciation because it would increase the amount of time in which freezing can take place on the planet. Plenary Now go back to page 2 in your workbook and tick which of the boxes under the Big Picture illustrates how much you have achieved in the lesson. |
Starter
Complete the Do It Now task on page 7 in your workbook - this is testing what you can remember from the last topic we studied last term as well as what you learnt about glaciation in your last lesson. Task 1 Now, click the link in your workbook to read key information from the BBC about how a glacier works as a system. When you finish reading about glaciers as systems, then look at the summary paragraph provided at the bottom of page 7. Use the words written in bold to label the black arrows on the diagram at the top of page 8. |
Task 2
Now look at the fill in the blank task beneath the diagram on page 8. Use the key terms underneath the paragraph to fill in the blanks. For example: The balance between inputs and outputs varies. In the winter, inputs usually exceed outputs near to the head of a glacier, this is called accumulation. Task 3 Next, watch the video provided at the bottom of page 8. Then, read over the detail at the top of page 9 about glacier budgets. Once you have finished reading, complete the budget calculations by subtracting the summer loss of ice from the winter gain in ice. For the total net glacial budget over 10 years, just add up all of the numbers you have written down. |
Task 4
Complete the Reflection tasks at the top of page 10. For example, if in your glacial budget the number was positive - that means the glacier grew. If the number was negative, that means the glacier shrunk. What could cause a glacier to grow or shrink? Plenary Go back to the top of page 7 and tick which of the big picture descriptions matched what you were able to accomplish in lesson today. |
Starter
Complete your Do It Now task on page 10. Remember you need to think back to the last lesson to identify what part of the picture is the accumulation zone and what part is the ablation zone. |
Task 1
Look at the table showing the glacier budget of an unnamed glacier. Use the data to answer the New Knowledge questions on page 11. Task 2 Look at the modelled example of a graph to show a glacier's budget and create your own using the graph paper on page 12 of your workbook. Stuck and can't print off the page? If you have access to Numbers or Microsoft Excel, you can put the numbers into a table and then produce a graph showing the glacier budget. Watch this walkthrough to help do this digitally. |
Task 3
Pen to Paper Task - move on to page 13 and complete the blanks illustrating what you have learnt about the glacier as a system over the past two lessons. Plenary Reflection task - answer the hand questions at the bottom of page 13 to review your knowledge, then go back to page 10 and tick the Learning, Mastering or Extending description that matches best with your achievements today. |
Starter
Complete your Do It Now task. You are to look at the three images on page 14. In the table below the images, you are to write down the similarities and differences of each of the pictures to each other. |
Task 1
Watch this video and then read all about erosion features of glaciation on page 15 in your booklet. Next, use the story board on page 16 to explain step by step how corries are formed using the first 4 scenes of the storyboard. Finished? Fill the last two scenes in with either the story of how an arete or pyramidal peak forms. |
Task 2
Complete the reflection task - Imagine you are stood at the bottom of the pyramidal peak in the picture at the top of page 17. Look around you, what do you see? How do you feel? Describe in the space provided the scene around you. Stuck? Have a look at this 360 video to help inspire your description. If you have VR goggles you can watch this and actually feel like you are there! Plenary Go back to the top of page 14 and fill in the Big Picture with which of the Learning, Mastering or Extending descriptions matches your achievements in today's lesson. |
