The 7th graders experience a variety of exciting hands on projects which help them understand a wide variety of physical science processes. The robotics project is a culmination of electronics and computer programming knowledge which challenges the kids to put their brains into high gear! In this case the students had to get a highly sensitive infrared monitoring device to become less-sensitive so it could essentially see only two things; the black line OR nothing (anything other than the black line / NOT the black line). This would allow the robot to stay on track. Can you figure out how they desensitized the receptors? Less
