  1. RSC/IOP TRAINING FOR CHEM/PHYS TEACHERS SUPPORTED BY PACN AJ BUKINDA, UGANDA 17-21 August 09

  2. Training team • Byamugisha Alex, Uganda coordinator AJ Bukinda • Jean M Johnson, UK and chemistry coordinator • Pat Johnson, UK chemistry • Francis Gatete, Rwanda IOP, physics coordinator • Wadido Moses, Buddo SS, physics • Cartland Richard, AJ Bukinda, physics • Mpamizo Gonzaga, AJ Bukinda, physics • Tukesiga Athanasius, AJ Bukinda, physics • Assistants: Joseph, physics (Rwanda IOP); Hashaka Alex, Moses, Diing and Josephat, chemistry (AJ Bukinda)

  3. Preparation older students now at university helped to mount posters and prepare gifts 5000 litres of water had to be addedby jerry-can!!

  4. Participants 29 schools were represented; in most cases a chemist and physicist came from each school They included high achieving schools like Immaculate Heart, Kigezi High, Maryhill, and Buddo SS, but also schools form villages like Kamwezi and Kihihi. Districts represented included Kabale, Kisoro, Rukungiri, Kanungu, Ntungamo, Mbarara, Wakiso and Arua. Also, Ketema, a chemistry teacher, came from Ethiopia. Our multinational chemistry team England Scotland Sudan Ethiopia Uganda Tanzania

  5. Colourful chemistry Food dyes were easily separated by chromatography; invisible ink and a chemical volcano gave a fun introduction to the course!

  6. The Periodic Table Great excitement as chlorine made in a Petri dish reacted with both aqueous bromide and iodide ions, showing it was more reactive! Jean demonstrated reaction of these ions with bromine, thereby showing how to illustrate simple and safely Group VII relative reactivities. The same Petri dish technique was used to show behaviour of nasty gases like nitrogen dioxide. RSC DVD Group I was illustrated by the chemistry teacher from Ethiopia, Ketema, with sodium reacting with water; the other Group I reactions were then viewed using the RSC DVD

  7. Use of plastic sheets to carry out cation analysis was also a completely new experience! • Other skills developed: • Thermochemistry using plastic cups • Simple redox using test tube reactions and DVD for reduction of CuO • Introduction to plastic sheet expts to illustrate relative reactivities of metals

  8. Organic chemistry We were able to demonstrate polymerisation and addition easily with simple models Formation of polythene Polymerisation to make PVC

  9. We carried out alcohol reactions with acidified dichromate and with a carboxylic acid, simply by immersing a test tube in hot water. First viewing of colours and observation of smells caused excitement! Teachers enjoyed the poster task on alcohol! Every teacher took away a box of Molymod models for use in his/her school

  10. Reaction rates Just 50 drops of reagent were used in each cell to investigate the thiosulphate/HCl reaction; good graphs were obtained.

  11. Moles …..are not really so difficult! Jean used varying mole ratios of aqueous lead ions and iodide ions to show the maximum ppt formed when there was twice as much iodide, hence the formula is PbI2 Pat explained how to find the formula of CuO, using data from the DVD experiment

  12. Ammonia Alex gave a superb demonstration of the Fountain Experiment

  13. Electrolysis …. a Daniell cell will be used in future courses We also Cu plated coins, linking to the malachite ore from Kilembe mines Electrolysis of salt ….. and books used as resources for posters!

  14. Alcohol distilled from bananas made a good ending!

  15. Neat equipment for electricity The physics team: back row, left to right Francis, Moses, Athanasius, Gonzaga

  16. Each school received TWO multimeters, previously heard of but not seen!

  17. Light made simple

  18. Balloons are useful resources for physics!

  19. Learning new uses for slotted masses ……… and using the super IOP calculator rulers!

  20. Ticker tape timers are not common in Uganda Gonzaga (left) and Joseph look at IOP literature

  21. messy! better! Presentation skills soon improved

  22. The team listen to the closing speeches

  23. Closing remarks by Nyakairu Cox Apuuli, Resident District Commissioner, Kabale District ‘Practical subjects like physics and chemistry create a strong and firm foundation for the transformation of our country …….. I thank the RSC and IOP from UK and Syngenta for funding this training for a week’
