P5’s Volcanic Eruptions

We started off the new term with a bang!  We tried to re-create a volcanic eruption using everyday chemicals.  We mixed vinegar and bicarbonate of soda in a bottle.  This caused a chemical reaction which created foam and gas.  The pressure built up inside the bottle until the lid was pushed off and the foam ran down the sides of the bottle and all over the ground (and Mrs Robley’s trousers!!!)

Here’s our thoughts:

I now know what a chemical reaction is that things mix together to create something new.  (Kieran M)

I now want to show my gran how to do it – I think I could teach her.  (Brad)

If I were to do this again I would advise the person shaking the bottle to do it quickly and run out of the way as fast as they can so they don’t get covered a.k.a Mrs Robley!  (Madyson)
