|Name of Activity||Speed Fans|
|Keywords||fan, LEGO, speed, touch sensor, programming, 1 Hour Total, 4-6|
|Grade Level||4, 5, 6|
|Time||1 Hour Total|
|Brief Description||The activity involves building a fan out of LEGOs and creating a MINDSTORMS program that will change the speed of the fan every time the touch sensor is pressed.|
|Lesson Objectives:||Gain basic understanding of programming with MINDSTORMS.|
|Materials Needed:||NXT Kits/ RCX Kits.
Computers with MINDSTORMS or ROBOLAB installed.
|Necessary Background||Knowledge of programming with MINDSTORMS.
|Procedure||1) Explain the basics of programming. 2) Distribute the kits and explain the task ( i.e. to build a fan that changes speed when the touch sensor is pressed) 3) Have the students build a fan out of LEGOs in their kits. 4) Let the students try to figure out how to program the fan on their own. If they need help explain to them how the power level of the motor can be changed every time the touch sensor is pressed thus changing the speed of the fan.|
|Extensions:||Program the fan using loops.
Use the activity to talk about air flow.
