As part of British science week, we were able to take part in a session of science activities at Copnor Primary School. Children from each year group were able to go and enjoy activities led by STEM (Science Technology, Engineering and Maths) ambassadors. The children from Langstone were able to work with pupils from other schools and behaved beautifully.
We took part in two investigations, one about what happens when bicarbonate of soda is mixed with vinegar. We put a balloon over a mixture of the two substances and found that they were able to blow it up! Our second investigation looked at what happens when we mix vinegar and salt, then add an old copper coin. Try it at home (with adult supervision, of course) and see what happens!
Finally we went outside and watched what happens when Mentos are added to a bottle of cola. We stood well back and luckily didn’t get soaked with the sticky mixture!
All three experiments showed what happens when substances are mixed together, so we were chemists, not just scientists!
