How to teach Science with a balloon and a plastic bottle

What does science have to do with a Balloon and a voltic bottle? You may ask.

For the longest time the misconception here has been that learning and teaching science is difficult and complicated but that is far from the truth.

In fact science is as relatable as the air we breathe – and all you need to prove that is a voltic bottle (or any other plastic bottle) with an amount of vinegar in it and a handful of baking soda in the balloon. Pour the baking soda from the balloon into the plastic bottle while simultaneously covering the mouth of the bottle with the mouth of the balloon. You will notice instantly the balloon filling up with air – carbon dioxide, which is produced as a result of a neutralisation reaction with the vinegar and baking soda.

It is really simple and clearly illustrates the chemical equations written and memorised from our science textbooks. And it is with this approach we can learn how to effectively teach science in our Ghanaian classrooms which doesn't only address the problems of limited funds and access to expensive lab equipment and materials but also makes teaching and learning fun and relatable.

This is purpose of Practical Education Network – to empower science teachers nationwide, to create "Outside the Box" thinkers and to demystify science both in and out of the classroom and all by using everyday local and cheap materials.
