Project Idea

From the experience of Chemistry Olympiad/ Joint School Science Exhibition

Chemical Lunch Box

• Self-heating lunch box• Exothermic reactions

• Iron, oxygen and water• Supersaturated solution, e.g. sodium thi

osulphate pentahydrate• Calcium oxide and water

• Safety

New Century Materials

• Compare polystyrene lunch box and biodegradable lunch box

• Compare wool and superwarm (poly-texapore)

Investigative study on polystyrene lunch box and biodegradable one

• Compare• Degree of complete combustion• Action on heat/ conc. Acid• Biodegradability• Effect of sunlight

Investigative study on wool and superwarm (polytexapore)

• Compare• Ability to keep warm• Stretching ability• Resistance to burn• Ability to absorb water

Amazing Miracle

• Use milk in making• Plastic• Glue• Invisible glove• Photographic film• Fire resistant paint

Toilet Save Our World

• Prepare cellulose acetate• Used to prepare a membrane for

reverse osmosis• To filter sea water to water with

lower salinity • Use for cleaning & irrigation

Home Chemistry

• Ketchup to clean the copper coins• Use soda, aluminium can to clean silv

er plate

Functions of teacher

• Introduce the project and gives some initial idea

• Arrange time for discussion, doing expt and correct for report

• Training their presentation
