|Grade Level||4, 5, 6, 7, 8, 9+|
|Time||1 Hour Total|
|Brief Description||Students will use the NXT/RCX datalogging feature to identify a hidden
letter of the alphabet using light sensor data.
|Lesson Objectives:||To program an NXT/RCX vehicle to collect data.
To analyze data and come up with a solution.
|Materials Needed:||NXT/RCX kits.
MINDSTORMS 2.0 with datalogging
capabilities orROBOLAB investigator.
Large print out of a letter of the alphabet.
Should cover a 8 1/2 by 11 sized paper.
|Preparation and Set Up:||Set up the hidden letter on the floor or on a table, but make sure that it cannot be seen.
Have pre-built NXT/RCX vehicles or allow students to construct their own.
Set up computer with MINDSTORMS 2.0 or ROBOLAB Investigator.
|Necessary Background||Datalogging is used to collect data from the sensors on the NXT vehicle.
This data an then be uploaded on to a computer an analyzed.
The light sensor will be used in this activity to collect information
about the color changes of the hidden letter.
|Extensions:||Limit the number of times you allow a car to drive over a letter.
Add a second light sensor to collect more data.
