Name of Activity NXT Elevator
Author STOMP
Keywords Simple Machines, Civil Engineering, NXT
Subject NXTs
Grade Level 4, 5
Time 2 Hours Total
Brief Description Students construct an NXT-based elevator to move a platform from one level to another and back. When completed the elevator should use a motor and a sensor to control it.
Lesson Objectives: – Learn what makes a structure sturdy
– Learn how to use pulleys and gears
– Practice basic programming
Materials Needed: – NXT kits
– extra Legos (mostly beams)
Preparation and Set Up: Make sure NXTs and Legos are available in the classroom.
Necessary Background None
Procedure – Introduce the activity with a story depending on the context. Go over the engineering design process, emphasizing that they should plan and sketch their design first – Sign off on designs before they can start building – Give students the rest of the first hour to build their designs. – At beginning of second hour, make sure all groups have finished building and start with programming the elevator. They should all use at least one sensor and one motor to control the elevator. (Students should have some prior experience with programming) – Test all of the elevators as a class
