Description
Why does the bubbly reaction happen in your volcano activity?
Reacting vinegar and bicarbonate soda together produces carbon dioxide and water.
The reaction is as follows
Vinegar + Bicarbonate Soda —> Carbonic Acid + Sodium Acetate
The carbonic acid is unstable though, so it breaks down into liquid water and carbon dioxide as a gas, causing the massive ‘build-up’ of pressure you saw in the experiment.
The water is left in the vinegar solution whilst the carbon dioxide rises, causing the bubbles to expand the detergent upwards and out of the volcano model.
Why do real volcanos erupt?
Teaching ideas that complement the volcano making kit
- Discuss the differences between the types of volcanos.
- What makes some volcanoes erupt violently and other not at all?
- Name towns and cities that have been destroyed by volcanoes.
- How can volcanologists predict when volcanos might erupt.
- Where in the world is a supervolcano?
- What are lava bombs?
- What is a pyroclastic flow?
- Why are soils around the base of a volcano so fertile?
- Where is the largest volcano in the solar system?
- Make a science poster about the structure of the Earth
I just wanted to pass on how much the staff and students really enjoyed it and how perfect it was to launch our science week activities. The students were enthralled, educated and entertained – a perfect trifecta!
-Caulfield Grammar School – Big Science Big FunThanks so much for presenting at our school on Monday. Our students enjoyed the show.
-Greenvale Primary School – Big Science Big FunFizzics Education curated a thoughtful and hands-on experience for the children, incorporating practical, skill-based learning activities and followed by a science presentation at the end of the event involving liquid nitrogen. This was delivered safely and effectively, capturing both the children and the parents for the duration of the presentation.
-Macquarie Bank – Family Fun DayFizzics Education ran a show today at our school and it was wonderful. He was a great facilitator and the show was age appropriate and well done.
