Volcanoes on our Planets

We know that there are lots of volcanoes in space.

The largest volcano in our solar system is on Mars, while Venus has the largest number of volcanoes.

Today we did a volcano demonstration (this is not an experiment or an investigation, rather it is a demonstration of how lava flows from a volcano).

We know that bread soda and vinegar will react together to give a gas called carbon dioxide.

If we add wash-up liquid and red food dye we can make our own erupting mini-volcano.

We tried to launch a rocket outside using the power of the gas build up from the reaction of vinegar with bread soda.  Unfortunately there must have been a slight crack in our rocket because we could see the fizz escaping and the rocket didn’t launch.
