Volcano Experiment

Today we tried another science experiment to see the reaction of two ingredients that make Carbon Dioxide gas.  Rob helped us build a volcano using sand.  Inside it went baking soda, red food colouring, dishwashing liquid and last of all the vinegar.  There was lots of foamy, fizzy lava gushing out of the volcano!

Later Rob asked us to pretend that we were the ingredients to act out the reaction.  Rob gave us a number (1, 2 or 3). The girls were the vinegar and the boys were the baking soda.   We mixed together and then we separated into our 3 groups.  The number 1 children turned into water.  The number 2 children turned into salt and the number 3 children were Carbon Dioxide gas!
