Have students explore the sue of energy in collapsing, falling and swinging actions. Repeat the collapse, but before giving in to gravity feel a real stretch away from earth. Lift before the collapse. Before the collapse go for a walk, run, leap and skip to a high level. Pull away from gravity for a few seconds, hang in the air, then collapse.
Falls are different from collapsing.
Falls bend or lean towards gravity rather than going straight downwards. Swings are a little like collapses, but the energy momentum carries through to rise and resist gravity. Feel yourself hanging as the movement rises away from the earth. Question students as they explore their use of energy in these activities. Explain to students that sometimes an image or a feeling might be associated with a movement.
