Primary 4 and Primary 4/5 took part in Science with Mrs Maher as part of STEM WEEK. Our theme was ‘George’s Marvellous Medicine’ and we made our own frothing foaming mixture that would explode Grandma away.
Today we used: food colouring in water, bicarbonate soda, washing up liquid and vinegar.
A simple chemical reaction took place when we added the vinegar because it reacted to the bicarbonate of soda. It created a gas, carbon dioxide and we saw bubbles trying to expand out of the liquid.
It was foam-tastic!! 🙂

Maths Sumdog Contest is still running!!
