Project Idea From the experience of Chemistry Olympiad

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 thiosulphate 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 silver 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
