Description

As part of a design challenge, students learn how to use a rotation sensor (located inside the casing of a LEGO® MINDSTORMS ® EV3 motor) to measure how far a robot moves with each rotation. Through experimentation and measurement with the sensor, student pairs determine the relationship between the number of rotations of the robot's wheels and the distance traveled by the robot. Then they use this ratio to program LEGO robots to move precise distances in a contest of accuracy. The robot that get

Performance Expectations

4-PS3-1   Use evidence to construct an explanation relating the speed of an object to the energy of that object.

4-PS3-4   Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.

MS-ETS1-2   Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
