In class we were given a case of a Fire at school the suspects were in the files and all suspects had a specific elements that started the fire. I tested all of the elements to figure out who started the fire. I gave a ranking on a scale from 1 to 10, 10 being the most, on the reactivity in water. My hypothesis was if the element has the highest reactivity then that is element that started the fire. Click here to read my lab report.
