Keywords mini golf, create, obstacle, 1 moving part, practical design, imagination, requirements, Simple Machines, 2 Hours Total
Subject Simple Machines, Non-LEGO
Grade Level K, 1, 2, 3, 4, 5, 6, 7, 8, 9+
Time 2 Hours Total
Brief Description Have students create a mini golf course, giving each pair the task of creating a single obstacle
and hole) for the course. Must have 1 moving part.
Lesson Objectives: - Experience in practical design.
- Implementing imagination to fulfill requirements while making an interesting requirement.
Materials Needed: - Simple Machine Kits.
- Marbles (lots of marbles).
Necessary Background Go to and choose the “minigolf” game for ideas of obstacle courses and such.
It helps to show this to the students if they are old enough to turn them into practical realities
as opposed to trying to recreate life savers floating down a river.
Procedure -present project -Give groups paper to plan -Let them build -put all together, test
Extensions: - Must have 2 moving parts.
- All sections must connect together.

Rat Race





Name of Activity Rat Race
Author STOMP
Keywords NXT, 1 Hour Total, vehicle, car, obstacle, obstacle course, contrasting colors, sound, sound sensor, constraints
Subject NXTs
Grade Level 4, 5, 6, 7, 8, 9+
Time 1 Hour Total
Brief Description Students will program their NXT vehicles through an obstacle course. The instructor
should be creative in making an obstacle course. The obstacle course can include a
contrasting colored floor, narrow passages that force students to design a compact car,
sounds that require students to use sound sensor, and walls that cars need to avoid.
Lesson Objectives: To learn about programming in NXT.
Materials Needed: NXT kits.
Computers running LEGO MINDSTORMS.
Obstacle course, be creative in inventing a fun obstacle course for students to program and design their car to get through.
Preparation and Set Up: Set up an obstacle course, it can be very simple to complex depending of the level and experience of the students.
Necessary Background Vocabulary:
  1. Introduce the activity and show the students the pre-built obstacle course so that they know what their car has to do.
  2. Have students build their cars using touch and light sensors. Remind students that their car must somehow break through the rope barrier at the end of the course.
  3. When students have finished building, have them program their cars to travel through the course.
    1. The cars must start at the start line.
    2. When the cars hit the black line, their cars should turn right.
    3. When the cars hit the wall, the cars should turn left.
    4. At the finish line, the cars must break through the tape.
  4. When students have finished programming allow them to test their cars, reprogram/rebuild if necessary and retest their cars.

Building a Mini Golf Course





Name of Activity Building a Mini Golf Course
Author STOMP
Keywords design, obstacle, groups
Subject NXTs
Grade Level 4, 5, 6, 7, 8, 9+
Time 3 Hours Total
Brief Description The class will work in pairs to build a mini golf course. Each group will design a different obstacle for the course.
Lesson Objectives: To use sturdy building to build an obstacle that can withstand being hit by a ball.
To design a moving obstacle.
To program the obstacle to move.
To work as a class to achieve a goal.
Materials Needed: - LEGO NXT kits
- Extra motors and gears
Preparation and Set Up: - Arrange students into groups of 2
- Distribute LEGO NXT kits
  1. Have students construct a pathway for the golf ball to travel down.
  2. Have students use a motor to construct an obstacle that the golfer has to pass to get the ball into the hole.
  3. Use sensors to activate or disarm the obstacle.
  4. Place the RCX out of the way of the golf course.
  5. Some ideas for obstacles students can build are:
    1. A claw
    2. A windmill
    3. Revolving doors
    4. Rotating platform
    5. Bat
  6. Program the RCX so that the obstacle reacts as the student wants.
  7. Have all the students put their designs together to complete the golf course.
  8. Test each golf hole with either a miniature ball or a real golf ball.
Extensions: Build a putter that will hit the golf ball onto the course.
Use trigonometry to find out how to get a hole-in-one for your golf course.
Have a mini-golf competition using the obstacles.
Modifications: This activity works well as a final project.
