LESSON PLAN Subject Unit Lesson Key stage Geography 1 How was formed? 3 Topic: Llyn y Fan Fach Objectives:  To discover how this glacial lake was formed  To learn keywords and label a diagram demonstrating its creation. Keywords: Llyn y Fan Fach, corrie, plucking, abrasion, tarn, moraine. Introduction/ISM: Timing Image of Llyn y Fan Fach – how was this lake created? Classroom discussion. 5 mins Explain the history of Llyn y Fan Fach describing where the lake is. Llyn y Fan Fach is a 10 hectare lake on the western side of the Beacons. The lake itself is overlooked by the mountain peaks of Picws Du and

Waun Lefrith. The northern face of Waun Lefrith was home to a glacier during the Ice Ages which gouged out the corrie (or cwm) in which 10 Llyn y Fan Fach now sits. mins Describe using the PowerPoint how a corrie lake is formed over time. Activity one 10 Describe how a corrie lake is created mins Activity two

Draw and label a corrie. Pupils should use all of the keywords in their diagram and make sure that their earlier description includes meanings of all keywords. More able pupils (or classes) should use worksheet ‘draw and label the formation of a corrie’ and should draw and label the formation at the beginning 15-20 of the last Ice Age, during the Ice Age and after the Ice Age. mins

After pupils have completed their tables, they should close their workbooks.

Pupils should then match up keywords and meanings on the attached 10 worksheet from memory. If short on time this can be completed as a class mins activity through the PowerPoint. Plenary: Conclude by discussing whether pupils know of any other corrie lakes. Extension work: Pupils could look on the internet to find other examples of corries and tarns. Differentiation: ALN pupils can use the attached worksheet when labelling and drawing a corrie. MAT pupils should complete the ‘draw and label the formation of a corrie worksheet’ Assessment: Through classroom questioning and through marking of classwork. Resources: PowerPoint, match the keywords worksheet, label a corrie worksheet, draw and label the formation of a corrie worksheet. Links to literacy/numeracy: Literacy - This lesson can link to literacy in the following ways:  Pupils are asked to speak clearly using appropriate language  Expand upon ideas with supporting reasons.  Select and organise ideas and information to give a clear and full account.  Listen to explanations of processes, sequences or points of view and identify the main points in order. Numeracy - This lesson can link to numeracy in the following ways:  Time events and organise results.
