Web quest Content q Introduction - sets the stage / provides background info q Task - must be doable, interesting / linked to syllabus topic & objectives/ linked to real world inquiry based learning q Resources - ICT - internet, OERs, concept mapping, simulations, digital story, presentation, word, spreadsheets etc. ; Non-ICT textbooks, library, newspapers, magazines, photographs, school environment, real objects, pen, paper, blackboard, chalk, community experts, science equipment and mathematical instruments, etc. q Process - steps students should take to complete task q Guideline – some guiding questions, directions on how to organize the information q Evaluation – student project presentation; evaluation with rubric made by teacher and shared with class to evaluation student webquest project q Conclusion – recap what have we learned. What questions remain to be answered?

Introduction How are drugs made? What do the following have in common; match box, gun powder, paper? How is sulphur extracted? What are the physical propertities of Sulphur (iv) oxide? What are the chemical properties of suphuric acid? What are effects of Sulphur (iv) oxide to the environment?

Task You will be divided into 6 groups labeled G 1, G 2, G 3, G 4, G 5, G 6 In your groups you will research on: ◦ G 1 the sources of Sulphur& the extraction of sulphur ◦ G 2 the preparation of the allotropes of sulphur, oxides of sulphur ◦ G 3 the properties and uses of sulphur, oxides of sulphur ◦ G 4 the contact process, properties and uses of sulphuric (VI) acid ◦ G 5 the preparation and properties of hydrogen sulphide ◦ G 6 pollution effects of sulphur containing compounds

Task Your will work collaboratively to do research from the internet, text books and conduct experiments in the laboratory. The results of your inquiry will be presented using MS Power. Point and MS Word to the class. Your work will be evaluated and shared to the rest of the members of the class. The best team will get a whole packet of digestive biscuits.

Process v. Select a group chairperson and secretary v. Allocate tasks to members in your groups v. Complete the work given in groups by following the links. v. Make notes on your findings. v. Summarise your findings v. Using a word processing software, prepare and submit a written report of the task you performed as a group v. Prepare a power point presentation and present your experimental work to the class ; share the work among yourselves so that each person presents a section

PROCESS Group responsibilities: Each group must have a leader, a researcher, and a material gatherer. Leader- will oversee designation of roles to each group member based on their capabilities. She will also be responsible for the collation of all data that will be used for the presentation. Researcher- will participate in researching, exploring and examining information relating to the task. Material Gatherer- will be responsible for gathering instructional tools needed for the task.

Guidance From the above web linkages extract and compile information into Slides on your area of research. G 1 Name the sources of Sulphur &Describe the extraction of sulphur with help of flow charts G 2 Describe the preparation of the allotropes of Sulphur, properties and uses of sulphur G 3 State the preparation, properties and uses of oxides of sulphur G 4 Describe the contact process using flow charts, properties and uses of sulphuric (VI) acid G 5 Describe the preparation and state properties of hydrogen sulphide G 6 Explain pollution effects of sulphur containing compounds

Guidance Further v Access the photo library of your specific area – Observe and take notes v Access the Video Library of your specific area and observe keenly the process or properties v Conduct actual experiments with assistance of the teacher/lab technician based on the videos from the links v Take all relevant notes about your area for use in compiling the report

Guidance v. Each group should complete the tasks v. Organize your presentation neatly so that it communicates very clearly v. Make sure you organize, analyze and synthesis information from all sources v. Ensure you interact, collaborate and work together to complete your project

Conclusion - Project Presentations It will involve three stages. 1. Exposition and launch of the project through webquest slides – 1 lesson Teacher and Students 2. Conduction of project work primarily by students with assistance from Teacher, Computer and Science technicians. - 3 lessons 3. Compilation of presentation slides and materials – 1 lesson. 4. Presentation, evaluation, reflection and ranking of group work – 2 lessons

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 100 Comment

Conclusion- Reflection Its my believe that if you immerse yourself in the tasks ahead learning will be more enjoyable and result to deeper understanding of various concepts through the interaction with technology and fellow students. The presentation of group work will provide you with an opportunity to show case your efforts and teach your peers in a new way.
