Grade 5 Design and Technology Level 2
Car Windshield Wiper
Students of Grade 5 were explained that the car windshield wiper works on the principle of Linkages and 2 mechanisms:
· A combination of electric motor and a gear provides power to the wiper.
· A four bar mechanism converts the rotational output of the motor into an oscillating motion.
Students got informative as well as a practical experience of the same by preparing the model by themselves and observe it working.
