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

participantsparticipants29 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.

team

Colourful chemistryColourful chemistry
Food dyes were easily separated by
chromatography; invisible ink and a chemical volcano gave a fun introduction to
the course!
66
The Periodic TableThe 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.
77
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!
88
Organic chemistryOrganic chemistryWe could not find any shop that sold a liquid
alkene, but were able to demonstrate
polymerisation and addition easily with
simple models
99
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

Reaction ratesReaction rates
Just 50 drops of reagent was used in each cell to investigate the thiosulphate/ HCl reaction; good graphs were obtained.
1111
Moles …..Moles ….. are not really so difficult!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 PbI2
1212
AmmoniaAmmonia
Alex gave a superb demonstration of the Fountain Experiment
1313
Posters …. began to make sense!Posters …. began to make sense!
Water….
lone pairs make it polar, so it’s attracted to a charged rod
1414
Electrolysis …. Electrolysis …. next time, we need a Daniell cell!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
1515
Alcohol distilled from bananas Alcohol distilled from bananas made a good ending!made a good ending!

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

Balloons are useful resources for physics!
2121
2222
Learning new uses for slotted masses ……… and using the super IOP calculator rulers!
2323
Ticker tape timers are not common in Uganda
Gonzaga (left) and Joseph look at IOP literature
2424
Presentation skills soon improved
2525
The team listen to the closing speeches
2626
‘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

Commissioner, Kabale District
