A fun vinegar and Bicarbonate of Soda (Baking Soda) experiment.
In the first part of the video Lizzie Witch works magic on a glove.
In the second part we show how this can be achieved without magic. In other words ‘clever science ‘.
There is also a simple explanation of the process which is an acid reaction.
So, with the help of an adult, children can produce the same results as Lizzie but …..is that enough? Well, in my opinion it isn’t! I think once they have repeated the experiment they need to investigate further. This is where the creative thinking comes in and that is so important!
So what can they do now?
Well, here are some suggestions:
- What happens if you add less or more bicarb to the same amount of vinegar. Get them to predict what they think will happen before doing the experiment.
- does changing the kind of vinegar change the results?
- Can you use different thicknesses of gloves?
- Can a balloon be blown up in this way.
