Bicarbonate of Soda & Vinegar

Pupils from Years 5&6 have had a great afternoon, learning about irreversible reactions. Mrs Cooke’s, Mrs Robinson’s and Mr Mansfield’s class went out onto the yard, armed with some Bicarbonate of Soda and vinegar, to see what happens when the two are mixed together. Pupils carefully measured out the Vinegar and Bicarbonate of Soda, before mixing them in a glass bottle. A balloon was then immediately stretched out over the top of the bottle to catch all the Carbon Dioxide that was created from the reaction. Pupils were able to use a tape-measure to measure the circumference of the balloon. They then increased the amount of Bicarbonate of Soda to see if that had any effect on the amount of Carbon Dioxide produced.

As a special treat, the pupils then observed a similar reaction with Mentos Sweets and Diet Coke. They loved watching the diet coke shoot high into the air. See the video here

We will post the best scientific write-up here by the end of the week!
