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.

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

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

Balloons are useful resources for physics!

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’
