Bubbles come
when the water’s hot,
but what happens
When it’s not?

Getting Started:

• Watch the bowl as Mum or Dad pours in some boiling water from the kettle.
• Now sprinkle in a teaspoon of bicarbonate of soda–be careful, remember the water is very hot! Now watch what happens.
• Now do the same thing with cold water. What happens this time?

Did You Know:

When bicarbonate of soda comes into contact with hot water it releases carbon dioxide gas, which causes it to bubble, froth and foam. When you mix it with cold water nothing happens at all.
