FRIDAY, 1 MARCH 2013 Science focus: understanding energy conversion in a pendulum Language focus: vocabulary Technology focus: using a gizmoMaterials• Computer (log on): open e-mail with username & password• Science notebook with homework notes• Pencil, eraser, highlighter
LEARNING OBJECTIVESTODAY, I WILL Observe how the potential energy, kinetic energy, and total energy of a pendulum change over time as a pendulum swings. Identify the part of a pendulum swing in which potential energy is maximized and the part in which kinetic energy is maximized. Interpret a graph of potential and kinetic energy. Calculate the potential energy of a pendulum. Calculate the kinetic energy and velocity of a pendulum based on its height change.
Homework For first Science block next week Read & complete the handout. Hand it in to your Science teacher.
