Each group needs:

• 1 EV3 basic robot (Note: LEGO MINDSTORMS EV3 robot, such as EV3 Core Set (5003400) at https://education.lego.com/en-us/products/lego-mindstorms-education-ev3-core-set/5003400#lego-mindstorms-education-ev3; instructions to build and program a basic robot are included with the robot kit; a sample program for "pushing" and "pulling" is attached to this activity; if not enough robots are available for one per group, share among several groups or the class by taking turns with the robot.)
• 1 stuffed animal
• string or yarn to make a secure loop around the stuffed animal, and a hook (make one by bending a paper clip) (Note: This is to attach to the robot so the robot can pull the stuffed animal.)
• Pre-Activity Content Assessment, one per student
• Post-Activity Content Assessment, one per student

Note: This activity can also be conducted with the older (and no longer sold) LEGO MINDSTORMS NXT set instead of EV3; see below for those supplies:
