Pendulum Nose Challenge

It swings back but does not hit the release point. Ask students to predict what will happen. Release pendulum from teacher's nose without pushing; stand still. Key idea: Without extra energy, it cannot rise higher than where it started. Ask: Why doesn't it come back higher? Safety and cleanup: Teacher-only; secure pendulum and clear area. https://www.google.com/search?q=%22Pendulum+Nose+Challenge%22+science+demonstration+experiment
