Science Experiment!

Wow what fun we have been having with Mrs O'Leary!

We have been exploring the question "What causes volcano eruptions?"


Here are some responses:
We have found out that air pressure in the ground (Preston)
It's when the ground shakes and explodes (Ruby)
The ground shakes, air pressure under the ground needs somewhere to go so it explodes (Seth.D)
The ground heats up, the water underneath heats up then explodes (Taj)

Mrs O'Leary first put vinegar into a bottle and then put her finger underneath a funnel and quickly put two teaspoons of baking powder into the funnel with her finger still there. Then she quickly tipped the baking powder into the bottle of vinegar and as fast as she could pushed the cork into the bottle and the vinegar and baking powder reacted and made the cork shoot out of the bottle extremely fast and up into the air.
