3. 3preparation Old boys now at university helped to mount posters and prepare gifts 5000 litres of water had to be added by jerry-can!!

4. 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 chemist, came from Ethiopia. Our multinational chemistry team

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

6. 6 The Periodic Table Group I was illustrated by Ketema, with sodium reacting with water; the other Group I reactions were then viewed using the RSC DVD RSC DVD 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.

7. 7 First attempt at a poster: teachers could not understand what we wanted! 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 Use of plastic sheets to carry out cation analysis was also a completely new experience!

8. 8 Organic chemistry We could not find any shop that sold a liquid alkene, but were able to demonstrate polymerisation and addition easily with simple models

9. 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. 10 Reaction rates Just 50 drops of reagent was used in each cell to investigate the thiosulphate/ HCl reaction; good graphs were obtained.

11. 11 Moles ….. are not really so difficult! Pat explained how to find the formula of CuO, using data from the DVD experiment 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 PbI 2

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

13. 13 Posters …. began to make sense! Water…. lone pairs make it polar, so it’s attracted to a charged rod

14. 14 Electrolysis …. next time, we need a Daniell cell! Electrolysis of salt ….. and books used as resources for posters! We also copper plated coins, linking to the malachite ore from Kilembe mines

15. 15 Alcohol distilled from bananas made a good ending!

16. 16 Neat equipment for electricity The physics team, back row, L to R Francis, Moses, Athanasius, Gonzaga

17. 17 Each school received TWO multimeters, previously heard of but not seen!

18. 18 Light made simple

19. 19

20. 20 Balloons are useful resources for physics!

21. 21

22. 22 Learning new uses for slotted masses ……… and using the super IOP calculator rulers!

23. 23 Ticker tape timers are not common in Uganda Gonzaga (left) and Joseph look at IOP literature

24. 24 Presentation skills soon improved

25. 25 The team listen to the closing speeches

26. 26 ‘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 London, England …… that funded this training for a week’ Closing remarks by Nyakairu Cox Apuuli, Resident District Commissioner, Kabale District
