Pun Kwong CheungSKH Tsang Shiu Tim Sec Sch
Target group and stages
• F.6/7 Chemistry students• All 3 Chemistry teachers and others• Stages:
• Familiarization of data-loggers• May 2002
• Project proposals• Summer holidays
• Presenting project proposals• Experimental work
• End October – 1/11/2002• Project presentation and write reports
• Nov 2002• Final presentation
• 7/12/2002
Stage I
• Borrow equipment from ED• Perform some of the data-log experim
ents• Forms/experimental details : from the
CDI’s website
Photos: May 2002
Stage II : Project proposals
• Seminars:• How to write project proposals?• Searching information skills
• By school librarian
• Using KF (HKU): Students to discuss online
• Target:• To produce project proposals
KF
• Technical help from CITE, HKU• Some general topics for each
group:• What can data loggers do?• Project ideas – brainstorming• Refine ideas => project proposal
KF

What did they write?(Coke)
• How often do you drink cola ?
• We can do a experiment to find out the carbon dioxide • content in different cola , like coca-cola , pepsi .....
• and therefore we can recommend a "healthier" one (or the one which have a bad taste ^^) to others .
• The problem we have to solve is how to test dissolved carbon dioxide ? distillation ? or others?
• Please discuss and share your idea ....^^
Reflection journal (Student)
• What have we learnt?• Be confident to blame others by
evidence or reference• Realize the importance of other
members• Job distribution
Stage III:Presenting proposals
• Present their proposals
Stage III: Follow-up
• Skills in public speaking• General (Principal)• Using English (English teacher)

• Trial
Proposals
• Mouthwash• Water Quality• Vitamin in fruits• Washing powder• Coke
Stage III: Follow-up (I)
• Public speaking• General (Principal)• English (English
teacher)
Stage III: Follow-up (II)
• Trial• List of apparatus and reagents• Workable??
Stage IV:Experimental work
• Duration: from 23/10 to 1/11• Area A for TAS• Difficulties encountered:
• Some have to be monitored for a period of time
• Some require field work
Experimental work: Photos
Expt work: Movie clip
Stage IV (Cont’d)
• Solving difficulties:• Reschedule the lab periods
• No lab periods for other classes
• Field work : • Parent’s permission• Multi-tasking by teachers
Difficulties encountered
• Resources• People
• Principal, Staff from CITE, All 3 Chemistry teachers, Lab Technician, School librarian, Teacher Assistants
• $$$• QEF; TAS• Class’s grant (Approved by Principal)
• Equipment & Chemicals• ED
