[1] Demonstrate the Wheatstone bridge practically using real components included in your kit by connecting 5 LEDs and 5 resistors as a bridge circuit. See how 4 LEDs light up while the 5th LED, which is bridged, doesn't glow. The connections have to be made as shown in the circuit diagram below.
[2] Make a 2D drawing of the gear shown below from the ARC logo on OnShape.
You can refer to this image for the dimensions of the gear
