Each group needs:

• LEGO® MINDSTORMS® EV3 robot and additional LEGO parts including: 2 motors, 1 touch sensor and 3 wires to connect motors and sensors to the EV3 brain (LEGO MINDSTORMS EV3 robot, such as EV3 Core Set (5003400) for https://education.lego.com/en-us/products/lego-mindstorms-education-ev3-core-set/5003400#lego-mindstorms-education-ev3) [Alternatively, instead of a robot, have one student use a yardstick or measuring tape to measure and mark the given worksheet values.)
• pre-programmed EV3 brick and set-up instructions; use the online instructions available at https://www.youtube.com/watch?v=Dhe2jXi3Fc4 and the attached EV3 Robot Program (ev3) program file
• Pre-Activity Worksheet, one per student
• Activity Datasheet, one per student
• Post-Activity Worksheet, one per student

To share with the entire class:
