The Croc's used clay around a plastic cup to create a volcano. They then added water, bicarbonate of soda, paint and vinegar to create the volcano effect.
The children took turns to measure the ingredients and combine them together to carry out the experiment.
There were lots of open ended questions, lots of guessing and anticipating what might happen next. The Croc's really enjoyed the trial and error activity and showed great enjoyment when watching the final result.
