A few weeks into the school year, 8th grade science classes in Sherwood, Oregon were experimenting with baking soda and vinegar. In Mrs.Barrett’s fourth period class, Bailey Matthews, Allison Fiarito , and Kayla Wagner had been working on this lab together. The first day or two of that lab they had added small amounts of baking soda and vinegar and had been trying to figure out why it had bubbled/reacted. Once the lab was complete Mrs.Barrett told the class that they were going to do another lab with baking soda and vinegar. Some of the students had asked what we were going to do. Mrs.Barrett said we would find out tomorrow, and with that the bell had rung and class was over.

The next day had come, with fourth period science just around the corner. Once the bell had rung for fourth period Mrs.Barrett started the lesson. She told the class that they were going to be creating mini volcanoes. After that announcement Mrs.Barrett told the class that she was going to show them a presentation on the experiment. Once she had given that they could get started.

The presentation had covered the directions for the lab and the materials that were needed. They needed to grab a red tub that had contained the flask for the volcanoes. They also needed to get a cup of baking soda and a beaker full of vinegar. In …show more content…
The reaction was instantaneous, the mixture had bubbled up and over the edge of the flask spilling into the red tub. For the second test they had put in two spoonfuls of baking soda instead of one, but still adding the same amount of vinegar. It reacted in a blink of an eye, filling the flask with fizz. The last test consisted of three spoonfuls of baking soda and still 80 ml of vinegar. That time the explosion lasted longer than any of the others had. Riley Newman thought, “It was
