The Rwandan National Examinations Council is examining students on science experiments for the very first time this year
Speaking to The New Times, Apred Headmaster, Andrew, said, ‘We have been teaching science subjects theoretically, but now that there are going to be practical exams …… the acceptance of trainers from the RSC to train our teachers in chemistry practical has come at the right time and clearly demonstrates that they have great affection for the people of Rwanda’

The team
5
Qualitative analysis
We had to start with OL work, because teachers had very little practical experience; chemistry on
re-useable plastic sheets was also new!
6
Teachers knew the theory, but a reaction such as this confirmatory test for lead
ions was unfamiliar
7
This double indicator titration
gave a first taste of
volumetric skills for
many
8
Alex explains
the theory behind
using two indicators to analyse a mixture
9
Titration of hydrogen peroxide solution with potassium manganate (VII)
Our team approach helped teachers to develop the precision expected by examiners
10
Observing a silver mirror for the first time was exciting …………..
……… but most needed help in the interpretation of organic reactions
11
By day 3 teachers could easily explain their thiosulphate titration to a visiting scientist
12
They enjoyed the practical!
13
The chemical tie!
and the only female delegate!
