Introduction A group of F 3 Geography students from neighboring school wish to visit arid and desert areas to study about the action of wind. Their main concern is to explore and learn about the wind action and resultant erosional features

Task • In your groups, undertake a research and: a. You will explain the meaning of arid and desert areas so as to know what to expect b. You will inform them on the types of deserts and their respective examples c. You will also point out the action of wind and in detail concentrate on wind erosional processes and resultant features. d. You will make a presentation and impart the knowledge about your investigation findings to the mention F 3 Geography students from the neighboring school.

Resources - ICT • Computers • Projector • Internet website links(resource)

Resources – Non-ICT • • • Geography textbooks Exercise books/papers Pens and pencils Whiteboards Manila papers

Process • Step 1: Select a group chairman and secretary - chairman and secretary to assign roles to the group members • Step 2: Complete the work given in groups by following the links given below: • Definition of arid area https: //en. m. wikipedia. org/wiki/Arid • Definition of a desert https: //en. m. wikipedia. org/wiki/Desert • Types of deserts http: //www. onegeology. org/extra/kids/earthprocesses/desert.

Spice your presentation with images and video clips that your find to be necessary.

Guidance for research You are expected to : a) Define Arid and desert areas. b) State two categories of deserts and exemplify them. c) Mention three actions of wind d) Outline wind erosional processes and describe the features formed due erosion

Conclusion - Project Presentations • Each group will present its power point presentation to the rest of the class • The class will critique the presentations of your understanding. • Please note that you have 10 minutes for each of your groups presentation.

Evaluation Example - Student Project Evaluation Rubric Student Product Evaluation Fair 1 Satisfactory 2 Good 3 Excellent 4 Organization Presentation does not clearly communicate the topic information – even with spoken explanation Presentation communicates quite clearly topic information – but needs a lot of spoken explanation Presentation communicates clearly topic information – but needs spoken explanation Presentation is well organized, neat and communicates very clearly the topic information Quality of content Answers very few questions or none at all Answers some questions well Answers all questions very well and contains other interesting facts or conclusions Quality of group presentation Visuals and effects in the presentation are not effective – and they are distracting from the content Visuals and effects in the presentation are quite effective – and do not distract from the content Visuals and effects in the presentation are effective - – and do not distract from the content Presentation visuals and effects are very effective and improve the content – – and do not distract from the content Quality of group research Group has difficulty to organize and analyze information even with help Group can with help organize and analyze information from a variety of sources Group can organize, analyze and with help can synthesize information from a variety of sources Group can organize, analyze and synthesize information from a variety of sources Quality of group communicati on Group members have difficulty to work collaborate and effectively together even with teacher guidance Group members with a lot of teacher guidance can work collaboratively and effectively together to produce an original project Group members with some teacher guidance can work collaborative and effectively together to produce an original project Group members interact, collaborate and work effectively together to produce an original project Total score Score Comment

Conclusion- Reflection You have now researched and learnt about the action of wind in arid areas. Mention the wind erosional features whose formation are attributed to the following processes: a. Deflation b. Abrasion c. attrition
