1 Refurbishing an existing laboratory for learning and teaching of chemistry Kwong Tsz Kin ( 鄺子建 ) Chow Chi Wai ( 周志偉 ) Kwun Tong Kung Lok Government Secondary School 觀塘功樂官立中學 19 April 2012

2 Outline of Talk Reasons for Refurbishing the Chemistry Laboratory Planning of Refurbishing the Chemistry Laboratory Planning of the Preparation Room Learning and Teaching of Activities in New Chemistry Laboratory Ways to minimize accidents in Laboratory

3 Existing Chemistry Laboratory Oven Tall Storage Cabinet Fumehood SB4 SB5 SB6 Side Bench Side bench SB1 SB2 SB3 Teacher s bench Computer Desk Fumehood Diagram is not drawn to scale

4 Reasons for Refurbishing the Chemistry Laboratory NSS students were reduced Student bench working area is not large enough for performing experiment Not enough space for distribution of experimental materials to students Passage way is not large enough for student to walk through FumeHood is not able to remove all the toxic fumes FumeHood is not large enough to let more students to do experiment simultaneously

5 Old Laboratory Layout

6 Each bench accommodate 7-8 students

7 Only 1 power supply in each bench

8 Front Fumehood Rear Fumehood Near exit to chem prep room Concrete step

9 4 students in a table for experiment

10 Use side bench for performing experiment

11 Planning of refurbishing the chemistry laboratory

12 Workflow for refurbishing an existing chemistry laboratory Workflow Date Letter to ASD Jan 2011 Approval for ASD Apr 2011 Draft plan for ASD May 2011 Detail plan to ASD Jun 2011 Refurbishing chemistry Lab Jul Aug 2011 Finishing Refurbishing work Mid Sep 2011

14 Major Changes in new refurbishing chemistry Laboratory Numbers of Student Bench From 6 to 10 Orientation of Student Bench From Side to Front with leg accommodation Rear Entrance Move Backward for additional bench top FumeHood Move from 2 corners to back of lab Additional Bench Top in Teacher s Bench Additional space for trolley parking

15 New Laboratory Layout

16 Each bench can accommodate four students with facing forward to the blackboard.

17 Bench in the side with additional space for sink and town gas.

18 Sink cover is closed providing a large working area

19 Sink cover is opened for usage.

20 More space near fumehood for accommodation of more students

21 Old Door Rear Entrance : Move Backward for additional bench top

22 Power Supply and LAN node for internet and intranet connectivity

23 Drawers for storage each student apparatus set

24 2 fumehoods were re-located to the back of laboratory with larger space.

25 Fumehood provides a better illumination and ventilation

26 Fumehood can accommodation more students in performing experiment

27 Fumehood with side window can let them more easily to observe experimental result

28 Re-locate apparatus so that same type of apparatus can be collected simultaneously

29 Common Use Apparatus is clearly labelled

30 Common Use Apparatus with label and photo or diagram

31 Open shelf for Commonly use apparatus

32 Storage of Models

33 Storage of Lab. Coat

34 The Location of Oven

35 Additional space for trolley parking

36 Planning of the Preparation Room 1. Main Storage Area 2. Preparation, Dispensing & Cleaning Area 3. Clean Work Area 4. Trolley Park Area 5. Chemical Storage Area

37 1. Main Storage Area Storage Cupboard Door / Sliding door (glass) Fixed / Adjustable shelf Open shelf

38 Storage Cupboard

39 Storage Cupboard

40 Open shelf

41 Storage of of the long object

42 2. The Preparation, Dispensing & Cleaning Area Long bench / Additional bench Sink (double compartment)

43 Long bench

44 Long bench

45 Sink (double compartment)

46 Additional bench

47 3. The Clean Work Area (for administrative tasks)

48 The Clean Work Area (for administrative tasks)

49 4. Trolley park Area

50 Trolley park Area

51 5. The Chemical Store Area

52 The Chemical Store Area

53 The Chemical Store Area

54 Learning and Teaching of Activities in New Chemistry Laboratory

55 From Side to Front with leg accommodation

56 With the aid of visualizer can enhance L & T activities

57 Additional tables for Learning and Teaching

58 Distribution of experimental apparatus and chemicals

59 Distribution of experimental apparatus and chemicals

60 Collection of experimental apparatus and student assignments

61 Demonstration at Student Bench 10

62 Student perform experiment at Student Bench 10

63 Ways to minimize accidents in Laboratory

64 Auto-dispenser Auto-pipet

65 With the aid of heat proof mat can reduce the injury of heating

66 With the aid of micro-burner can reduce the injury of heating

67 With the aid of micro-scale experimental kits

68 With the aid of visualizer
