Building Erupting Volcanos

Building Erupting Volcanos

Pre School Strensall Montessori

This morning at circle time Pre-School made an erupting volcano as part of our dinosaurs topic. To begin with we talked about how during the time of the dinosaurs there were lots of erupting volcanos. We also discussed how we still have volcanos in our world today although many of them no longer erupt any more.


Building Our Erupting Volcanos

We worked together as a group to help do the different processes involved in creating and erupting our volcano. To begin with we had to build our volcano and we did this with some sand. We had to make sure we shaped the sand into a mound shape for our volcano and then into the top of the volcano we placed a plastic cup for our experiment.

After building the shape of the volcano we then explored the different ingredients and resources we needed for our volcano eruption. We didn’t know what clear liquid in the bottle was so we took it in turns to give the bottle a sniff. We found out that the liquid had a strong smell and from the smell we worked out the liquid was vinegar. We also talked about the other ingredients of paint, water, baking soda, washing up liquid and water.

We had a ‘recipe’ to follow to make the volcano erupt so we took it in turns to add the different ingredients to the cup we had placed in our volcano. Firstly we poured some water into the cup. We then added 5 teaspoons of baking soda, 1 teaspoon of washing up liquid and a squirt of paint. To make the eruption we then carefully squirted some of the vinegar into the cup as well. When the vinegar was added we watched our volcano erupt which was very exciting!

As we watched the volcano erupt we talked about the reason why it erupted when we added the vinegar to the cup and we learnt that the vinegar reacted with the baking soda to make it fizz and expand and flow out of the cup down the sides of the volcano!

We loved making the volcano erupt so much that we decided to do another eruption as well with a clean cup and all the same ingredients again!

This activity was done at circle time which meant it was quite a long circle time but everyone remained focused and attentive and really enjoyed being able to take their turn in helping to make our volcano erupt. Later in the morning we also added some other dinosaur figures to the tray with the sand and we had a dinosaur tactile tray to play in and explore. We used the timer to measure the amount of time children could play in the sand tray so that everyone who wanted to got a fair amount of time to explore the sand and dinosaurs.
