Great Hollow Scientists Cause Chemical Reaction

Students in Ms. Dicpinigaitis’ science class at Great Hollow Middle School recently completed a lesson on matter. Students hypothesized about whether or not the air in the classroom is considered matter. After weighing a small sample of water on a beam scale, the students added an Alka-Seltzer tablet to the water to determine if matter can be created or destroyed during a chemical reaction. The students re-weighed the water after the tablet dissolved and recorded their results.
