What you need:
• 1/2 cup Lemon Juice (2 lemons)
• 2 cups of Cold water
• 1 teaspoon baking soda
• 1 teaspoon sugar (Optional -this will make the lemonade sweet. If you don't want it too sweet, use less sugar)
• Glass
• Spoon

Simple chemical reaction
Baking soda is an alkaline substance and lemon juice is a acid and when the two ingredients combine, they create a chemical reaction that gives off carbon dioxide gas (which is completely harmless!). These are the same bubbles that carbonate soda.

Have the kids to explore with all 5 senses!
• Can they see the fizz?
• How about feeling the fizz?
• Listen quietly for the sound for the fizz?
• Smell the lemons!
• What does the fizzy lemonade taste like?

Play around with the quantities. Add more lemon for a greater citrus taste, add more bicarb of soda for greater fizz, add more water to dilute, add more sugar to make it sweeter. What is your perfect combination?

Science behind it

When the lemon juice (acid) and the bicarbonate of soda (base) mix, they form a chemical reaction known as an acid-base reaction. This is the same sort of reaction that you get when you mix bicarb soda and vinegar, such as in the classic erupting volcano experiment. The reaction produces as gas called carbon dioxide (CO2) which creates bubbles when formed in a liquid like in this fizzing lemonade experiment. This process is called carbonation.
