Today we learnt how different substances react when they are mixed with each other.
The materials we used for our volcano experiment are simple and can be found in your very own kitchen!
The items we used were:1 plastic cup1 drop of orange / yellow/ red food colouring Half a cup of vinegar 1 table spoon of baking soda
Aroha 6 were very excited to perform this volcano experiment. It was like witnessing a real volcano erupt right before your very eyes!
But this version is much smaller!
Congratulations AROHA 6 you have just created an erupting volcano!
Our discussion around this science experiment was
" What makes it behave that way?" Although there is actually a deeper explanation to that...
In other words, the primary explanation to the chemical reaction we have just experienced is that mixing vinegar, which is acid, and baking soda, which is base, results in the formation of carbon dioxide gas, forcing the contents of the cup to come out of the volcano.
When an acid and a base are mixed together, they react to neutralize each other resulting in production of salt and also in the process, produce carbon dioxide.
In real volcanoes, carbon dioxide is also present when they erupt!
