Second grade students concluded their study of volcanoes recently with a fun and exciting experiment. First, teams of students constructed miniature models of volcanoes of all different shapes and sizes. Then, each team was able to create an eruption within their model using a combination of baking soda and vinegar. The resulting “lava” then flowed out of the models in various displays – some flowing in great volume in a short period of time, while others flowed much slower for longer periods of time. Teachers were able to lead discussions and questioning following each eruption as students analyzed the results and postulated theories as to why the eruptions looked as they did. Great learning took place, and the students loved the activity!
