3 Volcano Experiments and other resources on volcanoes

After learning about the Layers of the Earth, Rock Groups and The Rock Cycle, we continued our learning about rocks and how they are formed by looking at volcanoes.
We started our learning about volcanoes by reading The Magic School Bus chapter book, Voyage into the Volcano. Full of interesting facts and a great story line, the magic school bus makes learning about science so much more fun. 
We used these Parts of the Volcano nomenclature cards to identify the parts of volcanoes and their names. I love how each part of a volcano is highlighted on each card and labelled making it easier to distinguish between the different parts and what they do.
The next part of learning about volcanoes was to make a volcano. We made three different volcanoes and here they are.

Volcano One - Sand Volcano
We made our own sand volcano and these are the things we used to make it:
  • 2 small plastic bottle
  • large dish
  • sand
  • funnel
  • red food colouring
  • vinegar
  • biocarbonate soda 
Here is how we made our sand volcano:
  1. Build a sand mountain around the plastic bottle, on the tray, to make the volcano
  2. Use the funnel to add bicardate soda into the plastic bottle (the volcanoes central vent)
  3. Add vinegar and a drop of red food dye into the second plastic container and stir it in (making  magma)
  4. Pour the vinegar container into the volcano and watch it erupt

As we conducted the experiment, we talked about how the magma inside the chamber can explode or pour out of the volcano which is then called Lava. Once the lava hardens it turns into rock.

Volcano Two - Underwater Volcano
Another book we read about volcanoes was The Magic School Bus Blows Its Top. This book taught us about under water volcanoes so we followed up our reading with watching The Magic Schoolbus Episode 14 Blows Its Top on youtube. 
We also learnt about tectonic plates under the ocean and how they moving causing earth quakes, tsunamis and volcanoes. 

So we made an underwater volcano and here is what we used:
  • small glass bottle
  • string
  • large glass bottle
  • hot and cold water
  • red food dye
Here are the steps we took to make our underwater volcano:
  1. Fill the large glass bottle up with cold water
  2. Tie a string around the top of the smaller glass bottle and fill it with hot water and a drop of red food colouring
  3. Slowly lower the small glass bottle into the large glass bottle and watch the underwater volcano take place.
We talked about how these underwater volcanoes can create new islands and are an important part of our environment.
Volcano Three - Volcano Kit
We purchased a Volcano Making Kit where we were able to construct our own volcano model.
The kit comes with everything you need to make your volcano. It has the mould, plaster, paint and instructions on how to make it.
Just like our sand volcano, we added bicarbonate soda to the volcano chamber and a drop of red food dye before pouring in the vinegar.
It doesn't matter how many volcanoes we made or how many times they erupted, my kids loved it! Isn't science fun!
