Fizz, Bubble, Pop!

A citrus chemical reaction science experiment.



















Here is a video of part of our lesson on this science experiment at Kindergarten.

Watch to see how to do this at home.

We all really enjoyed this experience!

What you will need at home:

Citrus Fruits

-Orange

-Lemon

-Grapefruit

-Lime


-Baking Powder/Bicarbonate Soda


-Containers to squeeze juice into


-Muffin Pan or other container to conduct experiment in


-Droppers or teaspoons


-Juicer or strong squeezing hands!


Conducting the experiment


Fruits high in ascorbic acid or vitamin C will produce o fizzy, bubbly reaction when combined with baking soda. When the acid from the fruit combines with the baking soda a gas is formed. This gas is carbon dioxide. You can see it through the fizzing and bubbles of the two ingredients!


Make sure you use your sense of smell with the citrus fruits before you begin experimenting.


TEST TO SEE WHICH FRUIT HAS THE BIGGEST CHEMICAL REACTION!


Add the juice from each fruit to the baking soda.


HYPOTHESISE: ASK QUESTIONS and GUESS OUTCOMES:


Will the smell of the fruits change after you add baking soda?


What will happen if you mix two of the juices together?


Which citrus fruit will have the biggest reaction?


To extend on this experience you could make a chart to write and draw your findings on.


Enjoy this time learning together!
