Presentation Transcript

  1. Project Idea From the experience of Chemistry Olympiad/ Joint School Science Exhibition

  2. 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

  3. New Century Materials • Compare polystyrene lunch box and biodegradable lunch box • Compare wool and superwarm (poly-texapore)

  4. Investigative study on polystyrene lunch box and biodegradable one • Compare • Degree of complete combustion • Action on heat/ conc. Acid • Biodegradability • Effect of sunlight

  5. Investigative study on wool and superwarm (polytexapore) • Compare • Ability to keep warm • Stretching ability • Resistance to burn • Ability to absorb water

  6. Amazing Miracle • Use milk in making • Plastic • Glue • Invisible glove • Photographic film • Fire resistant paint

  7. 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

  8. Home Chemistry • Ketchup to clean the copper coins • Use soda, aluminium can to clean silver plate

  9. Functions of teacher • Introduce the project and gives some initial idea • Arrange time for discussion, doing expt and correct for report • Training their presentation

  10. Resources: • Journal of Chemical Education • http://www.twingroves.district96.k12.il.us/ScienceInternet/ChemTopics.html • http://members.ozemail.com.au/~macinnis/scifun/projects.htm • Look around
