Exploding Volcanoes
1.
2. Chemical
Reactions.
Today we made volcanoes.
First we were split into four groups of four, (a mix of Year 1-3’s). Then we
went down to the sand pit where we built our volcanoes and little towns,
villages and forests.
When we were finished building we put a little plastic cup inside our volcanoes.
This would hold the baking soda and red food colouring.
We poured the vinegar into our volcanoes. There was a chemical reaction
between the baking soda and the vinegar. They frothed together and shot
out of our volcanoes. The red food colouring made the froth look like red hot
lava. The lava ran down one side of our volcanoes , but our towns ,villages and
forests luckily………..SURVIVED!!!
