Water Water Water

What with climate change and global warming, clean water is fast becoming a rare and much coveted resource. Living in Tanzania, one is very aware of the luxury of good, clean tap water. Watering your lawn seems a thing of the past. Harvesting water from the rains, which are becoming less and less predictable, is highly recommended and practised. Unfortunately, for the more marginalised of our communities, some people have no access to water. Women have to walk miles and miles a day to collect water for the house, never mind the livestock. 

Here at BISA, we have created a wetland from all our grey water, which we have been using to water our playing fields. We have also constructed a small dam at the bottom of the playing fields which is a great catchment area when the rains arrive. We encourage all our students to be water conscious and not leave taps running. Many of our taps on campus are timed and automatically switch off. We have also declared our campuses plastic bottle free areas and have introduced our new reuseable water bottles for staff, students and BISA fans. If you don't have yours, please enquire at the front office. 

With all this in mind, take a look at this article in the BBC called The Artistic Paradox of Ethopia's Water Woes. Let us be grateful for the water we have access to.

"...Renowned Ethiopian artist Aida Muluneh has taken a series of striking images to depict the harsh life of many women in rural areas - especially their daily efforts to obtain clean water for their families."


Chemistry is...Fireworks and Explosions!

Basic knowledge of chemistry helps you to read and understand product labels. Chemistry can help you make informed decisions. Chemistry teaches useful skills. Because it is a science, learning chemistry means learning how to be objective and how to reason and solve problems.

If you want to read more on why it is exciting and important to learn chemistry, follow this link. It isn’t a boring science. How could it be when it involves explosions and fireworks?


Cambridge International A Level Chemistry builds on the skills acquired at Cambridge IGCSE  level. The syllabus includes the main theoretical concepts which are fundamental to the subject, a section on some current applications of chemistry, and a strong emphasis on advanced practical skills.

The emphasis throughout is on the understanding of concepts and the application of chemistry ideas in novel contexts as well as on the acquisition of knowledge. The course encourages creative thinking and problem-solving skills which are transferable to any future career path like teaching and lecturing of chemistry, medicine, biochemistry, forensic science ,lab technology, pharmacy,  biotechnology, stem cell engineering, research science, chemical engineering, nuclear science, biomedical science and many more.


The Importance of Mathematics

Science, technology and engineering, so essential to the future success of any country, cannot thrive without practitioners having a solid mathematics foundation.

The importance of a solid mathematics education goes much beyond the current conversation of improved proficiency on test scores. I have used the word mathematics very frequently in my career but never until recently thought about the actual meaning of the word.

Once I looked from an Etymology perspective, I found interesting literal definitions in two ancient languages. In Greek, it is “learning.” In Hebrew, its root is “thinking.”

They tell us that mathematics gives us the critical ability to learn and think logically in any field of endeavour. The skills of learning today are more important than knowledge, which is so readily available on the Internet.

A solid foundation in mathematics and science develops and hones the skills of posing hypotheses, designing experiments and controls, analysing data, recognizing patterns, seeking evidence, conclusions and proof, solving problems and seeking absolutes, while being open to new information.

Studying mathematics not only will develop more engineers and scientists, but also produce more citizens who can learn and think creatively and critically, no matter their career fields. The workforce of tomorrow, in all fields, will demand it.

“The illiterates of the 21st century will not be those who cannot read and write, but rather those who cannot learn, unlearn and relearn.”

-Alvin Toffler

While physics and mathematics may tell us how the universe began, they are not much use in predicting human behaviour because there are far too many equations to solve. I'm no better than anyone else at understanding what makes people tick, particularly women.

Stephen Hawking


"Do not worry too much about your difficulties in mathematics, I can assure you that mine are still greater."

Albert Einstein


"A person who never made a mistake never tried anything new."

Albert Einstein

On Monday 9th September, Sixth Form students attended a university fair at United World College, Tanzania. Universities were predominantly from the UK and students got the opportunity to ask lots of  questions about potential courses.

There is another University Fair on Monday 30th September. BISA will be attending as there will be universities from all over the world.

At BISA we feel that it is really important our students understand what opportunities and courses are out there for them. It is also important to do your research and know what requirements are needed for the courses that you choose. It is an exciting time and we want our students to be prepared! 


On Saturday the 14th a group of Braeburn students took part in this year’s Triathlon at UWC and the following groups won in their categories:

Under 8 Team: Ruben, Larry and Alex

Under 13 Team: Isaac, Emily and Jasper.

Elite Team: Antonio, Clinton and Yuri.   

A hearty congratulations to these amazing BISA athletes! Well done!
