2. ?~ WHAT WAS I TESTING~ ?
I was testing: would a model volcano work??? I had my model volcano ( ) and all
my ingredients. I predict that my volcano will act like any other volcano. I also think it will
shoot out the mixture.
4. ?~WHAT I DID~?
First of all, I poured 2/3 of the base of the volcano with the vinegar. Then I got my
teaspoon and poured the bicarbonate of soda onto the spoon and poured that in the
volcano.

5. ?~WHAT HAPPENED~?
The volcano erupted! The vinegar reacted with the bicarbonate of soda and oozed out of
the volcano like lava.
