Transcript and Presenter's Notes

Title: Project Idea


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
