This document provides a lesson plan for using LEGO MINDSTORMS Education to simulate how plants move in response to sunlight. Students will program a robot to turn a motor for a specific period of time to follow a light source, demonstrating how plants track the sun. They will measure ambient light levels and variations in the room. The lesson encourages students to refine their robot design to more realistically model plant movement and behavior, such as incorporating ideas from Venus fly traps or programming their robot to return to a home point when dark.
