Lab work in science class is an experience that is essential to student inquiry and learning. In a position statement published by the National Science Teachers Association, they state: "A hallmark of science is that it generates theories and laws that must be consistent with observations. Much of the evidence from these observations is collected during laboratory investigations...These skills and knowledge, fostered by laboratory investigations, are an important part of inquiry-the process of asking questions and conducting experiments as a way to understand the natural world... Labs must be an integral part of the science curriculum." 

At St. Edward High School, we believe active and engaging learning experiences, like labs, are essential to build lasting knowledge across the curriculum. This week in Mr. Libero Puccini's physics classes, students worked collaboratively on an Impulse-Momentum Practicum. A car was launched from rest by a loaded spring as motion sensors linked to student computers graphed information needed for students to determine the change in the car's velocity. Once students determined the velocity, they then calculated the change in momentum. Using the graphed data, students were then able to calculate the average net force applied by the loaded spring. Applying Hooke's Law, they determined how far the spring was compressed as well as the spring constant. 

The classroom environment was exciting, and it was clear how much students valued Mr. Puccini's energy as he moved from table to table, challenging his students and asking leading questions to help foster deeper learning in this Lesson of the Week.
