Name of Unit Intro to NXT
Author(s) Westerman + Bhatti
School Arthur D. Healey
Teacher Garton
Brief Description Basic structure and programming of NXT robots will be explored, mostly through the use of cars. Because the curriculum was changed significantly after a couple of weeks, some of the earlier lessons also contain a focus on animal adaptations.
Grade(s) 4
Keywords Healey, Garton, 4th grade, NXT, cars
Number of Weeks 10
Week 1 Discussed animal adaptations. Built animals using NXT kit pieces (not incorporating the brick or motors).
Week 2 Had students attempt to incorporate NXT bricks and motors into their existing animal models.
Week 3 Started from scratch and had students build functioning NXT cars with at least two wheels that had the ability to move and turn.

Week 4 Finished building NXT cars (more explicitly guided this time to allow students to move on to the programming).

Week 5 Started programming the cars. Presented a series of challenges that didn’t require sensors
Week 6 Introduced sensors in the context of human senses, and talked specifically about the ultrasonic sensor. Gave challenges based on the ultrasonic sensor.
Week 7 Continued work on the ultrasonic sensor challenges.  Many more groups were able to be successful given the extra time.
Week 8 We introduced the idea of loops as well as the sound sensor.  The class then attempted to create robots that could play a sound version of “Red Light, Green Light,” where robots had to alternately move and stop on hearing sounds of a certain volume.

Week 9 Started the final project, which was a Rube-Goldberg machine involving robotic cars.  Each car starts in one of a series of consecutive blocks on the floor, and has to contact the robot in the adjacent block to make it move.
Week 10 Continued work on the Rube-Goldberg machine and completed a final test.
