Today it was Year 3’s turn to come for the science experiment enterprise with year 4. A few children turned up and had a lovely time exploring what happens when you mix together bicarbonate of soda, washing up liquid and lemon juice.
The bicarbonate of soda, when mixed with lemon juice, is forming carbon dioxide gas. As this fizzes up in the washing up liquid, it creates lots of soapy bubbles – wow! Is science magic?
