|Name of Activity||Light Symphony|
|Keywords||light sensor, NXT, tone, ambient light, loops, math blocks, sound, inputs, outputs, Engineering Design Process|
|Grade Level||4, 5, 6, 7, 8, 9+|
|Time||1 Hour Total|
|Brief Description||In this activity, students will wire a light sensor to their NXT bricks. Light sensor data
will be collected and used in a program that plays a tone based on the ambient light
in the room.
|Lesson Objectives:||- To learn to program using the light sensor, loops, math blocks, and sound.|
|Materials Needed:||- NXT brick.
– Light sensor.
– Computers running MINDSTORMS NXT software.
|Preparation and Set Up:||Set up computers with MINDSTORMS NXT Software.
Arrange students into groups of two.
Distribute necessary materials.
engineering design process
|Extensions:||Get students to match the pitch of another NXT brick.|
|Modifications:||- This same activity could be done using the proximity sensor attached to a car.
– Students could program their NXT brick to play a tone depending on how close their car was to an object. This could be related to a safety device that would warn you if your car was going to bump into a wall.
