Activity 10: Solving energy problem Page 24 Information Sheets 18 to 5 energy demand in a Objective: to understand the energy policies of Hong Kong sustainable way and/or other countries, and analyze whether such policies are sustainable * can choose to study the case of Hong Kong only or the case of Hong Kong and India/Singapore according to the abilities of students 20 Pages 36-43 -2. Be an energy-saving ambassador Objective: to understand how individual can help in energy saving *different kinds of exercises are provided to cater for learner diversity Page 25 IV. Catering for Learner Diversity 1. For students with average ability, teachers can let them finish the basic parts of the worksheets. 2. For students with better ability and are interested in this subject, teachers can let them complete the basic parts of the worksheets. In addition, they can choose different kinds of teaching activities, such as group discussion, role play, etc. Students can complete the part on “Extended Activity” and “Further Reading”. 6 Appendices Appendix 1: Competition – Classification of energy resources Type of activity: group competition Suggested procedures: 1. Students are divided into 6-8 groups (about 5-6 people in each group). 2. Each group will be given: a. The worksheet on P.8 of this document. (Please print on A3 paper when use). b. A set of word cards (see pages 9-10. It is recommended that they are laminated so that they can be reused.). c. Blue tap. 3. Students are required to classify the types and characteristics of the energy resources and affix the word cards onto the A3 worksheet within the time limit. 4. A small gift will be awarded to the group which completed the worksheet first to arouse students’ motivation in participating in this activity. 7 Energy Resources Characteristics Characteristics Examples Examples 8 Renewable Energy Non-renewable Energy Coal Oil Natural Gas Nuclear Power Wind Power Solar Energy Geothermal Energy Biofuels 9 Hydroelectric Wave Energy Power Inexhaustible Use inexhaustibly supply Limited Will be exhausted reservations Renewable within a Non-renewable short period of within a short time period of time 10 Appendix 2: What are the environmental problems caused by exploiting and using fossil fuels? Types of activity: group discussion and oral presentation Suggested procedures: 1. Students are divided into 6-8 groups (with about 5-6 people in each group). Each group should elect a group leader. 2. Each group will be given different sets of information (pages 7-10 of the Information Folder: Information Sheets 5 to 8). Some groups may have the same sets of information. Example: 3. Information Sheet 5 Information Sheet 6 Information Sheet 7 Information Sheet 8 Group 1 Group 2 Groups 3-4 Groups 5-6 Groups 1-2 Groups 3-4 Groups 5-6 Groups 7-8 Students read the information and discuss among themselves. Time allowed is about 10 minutes. Students should: a. identify the environmental problem shown in the information sheets assigned to their group and put it onto the space provided in the title of the box on page 12 of the worksheets. b. discuss how such environmental problem is caused by exploiting and using of fossil fuels and put their answers onto the space provided in the box on page 12 of the worksheets. 4. Group leader will present the results of their discussion. Other students should record the answers onto the table on page 12 of the worksheets. 5. Teacher gives conclusions to the discussion. Extended activity: 6. Ask students to prepare a concept map on page 13 of the worksheet at home to illustrate the “environmental problems caused by exploiting and using of fossil fuels” 11 Appendix 3: To use “nuclear” or not? Type of activity: debate (informal) * Suggested procedure: 1. Students are divided into the “pro” side and the “against” side (each side is sub-divided into 3 groups, with 6-8 people in each group). Motion: “We should develop nuclear power for generating electricity” 2. Each group of students should collect the relevant information, and should: a. Summarize the arguments which favor their side. Write down the discussion results onto Table 1 of page 22 of the worksheets. b. Prepare questions to attack the viewpoints and rationale of the opposite side. Write down the questions onto Table 1 of page 22 of the worksheets. (Procedures 1-2 can be conducted earlier [suggested to be one week before] so as to allow sufficient time for students to collect and organize the information.) 3. Start the debate: (Ask students to record the main points during the debate onto Table 2 of page 23 of the worksheet.) a. One representative from the “pro” side (Group 1) should speak first. He/She should b. c. d. e. describe their views and give two reasons to support the views. Time limit is 1 minute. One representative from the “against” side (Group 1) should speak first. He/She should describe their views and give two reasons to support the views. Time limit is 1 minute. One representative from the “pro” side (Group 2) should continue to give two reasons to support their views. Time limit is 1 minute. One representative from the “against” side (Group 2) should continue to give two reasons to support their views. Time limit is 1 minute. One representative from the “pro” side (Group 3) should raise questions for the “against” side. Time limit is 1/2 minute. f. One representative from the “against” side (Group 3) should reply the questions. The time limit is 1/2 minute. Then they should raise questions for the “pro” side. Time limit is 1/2 minute. g. One representative from the “pro” side (Group 3) should reply the questions. The time limit is 1/2 minute. h. Time for questions and answers. Time limit is 2 minutes 4. Teacher gives conclusions to the debate. 12 5. Students are required to complete Table 3 on page 23 of the worksheets at home to consolidate the main points mentioned in the debate, i.e. the arguments for and against the use of nuclear power * Teacher can conduct a formal debate if students are capable or interested in the topic. Students can collect information by themselves. 13
