+First, notice that moving the micro:bit in any direction, you will change the acceleration value, which is being displayed as the same color as the micro:bit. And notice that by moving the micro:bit, there is a changing acceleration value. Second, the flat colored horizontal line will start a waving line to display the value of the strength as measured in milli-gravities. Finally, notice that the LED display will fluctate based on the movement of the micro:bit simulator.

 Run the acceleration experiment by moving the actual micro:bit and observe the changes in the black line.  
 Vigorously move the micro:bit in the micro:bit simulatator by moving the micro:bit image from side to side. Every time the micro:bit moves in any direction in the simulator,  you are generating data points that can be reviewed in Excel. The more attempts to move the micro:bit from side to side, the more data being saved in Excel. After you have vigarously moved the micro:bit simulator from side to side for a sufficient amount of time, you are ready to graph or chart the accceleration of the micro:bit. We want a printout of our acceleration on Excel that can be graphed in Excel.
