Volcanos in the Pacific – a tactile science experiment for kids of all ages.
Wallis and Futuna are two small island groups in the South Pacific between Fiji and Samoa that were settled by French missionaries at the beginning of the 19th century. It is now classed as an “Overseas Territory” of France and there are 3 kings who assist in rule with a parliament of 20. While Wallis and Futuna are not necessarily a “country” in a technical term, they do have one very exciting element that can’t be missed in any child’s upbringing… Volcanos!
Futuna in particular is a volcanic island, and thus we can’t pass up the opportunity to bring out the baking soda and vinegar experiment that we all loved so much as children.
Now, if you need a refresher on volcanoes (also linking up that big picture by making clear links to the work we’ve been doing around the sea and space) then check out this video (with or without your child, depending on how old they are and how much they watch).
The video will run you through how to create your volcano (instead of building one you may wish to do it at the beach with a sand volcano with bottle inside, though our little group enjoyed the measuring, mixing and making of the volcano just as much as the actual eruption.)
When you conduct this experiment, you may wish to focus entirely on the power of volcano’s to form the land (such as the islands Wallis and Futuna) but if you have a budding chemist in your group, then you might want to take it further and conduct a series of volcanic experiments to asses the chemical reaction in their own right. Ie Bicarb and water (no visible reaction), Bicarb and vinegar (bubbles), Mentos and diet cola (explosive bubble reaction).
Ask kids to predict what they think will happen in each instance, hypothesise what the reason is for the different reactions and realise that there is nothing “wrong with being wrong” in science (A negative result tells you as much as a positive one!)
Having read a little about chemicals with the 5yo, I was surprised that she later formulated a hypothesis about the volcano that was quite accurate; She thought that there was a chemical reaction that made a gas and that created the bubbles that she saw. While this is probably not going to be a fact that she remembers later, the process of linking known information and apply it to new situations and observations to form a new hypothesis is something we want to encourage at every point possible on the road to adulthood!
We’ll later have a little road trip to look at more detail about where the heat for real Volcanoes comes from, but this little science experiment is a great place to get those little scientists thinking!
