Baking soda experiments or activities are a great, safe and easy way to introduce the concept of a chemical reaction to children. Baking Soda is alkaline and reacts with acids such as vinegar, releasing carbon dioxide ( a gas ) and water. The fizz produced is brilliant fun for children to watch especially if you combine with washing up liquid ( dish soap ) to make even more bubbles or add a bit of food colouring, ice or a theme.
Here are some of our favourite baking soda ( bicarbonate of soda ) experiments
How about making a few boats with different sized bottles, straws or using different amounts of baking soda. Can you predict which will move the furthest/fastest?
We tried a bit of baking powder in this activity, can you find out which works best? Baking powder or baking soda?
The baking soda volcano is a staple science activity for kids. Can you try using different amounts of vinegar, but keeping the washing up liquid and baking soda the same? How much do you need for an eruption?
My children loved these! How much baking soda does it take to make the canister pop? Do be carefully though, and stand well back!
This is a brilliant twist on the traditional volcano from Toddler Approved.
Make rocks and watch them fizz! Can you hide something inside them?
Make some colourful baking soda ice cubes and watch them fizz as you add vinegar.
Inspiration Laboratories froze the vinegar instead of the baking soda which worked brilliantly as well.
Watch raisins dance around a glass due to bubbles of carbon dioxide.
Finally, make a very impressive sandwich bag with Steve Spangler.
