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.
