Tagger Arm Building Instructions

This file contains building instructions for the Sudoku Solver from tiltedtwister.com. The arm for the pen attachment is a great model to follow for the robo tagger. The pen is raised straight upward in this model as opposed to swinging upward at an arc, which most students will do resulting in poor quality lines.

Geared for Speed Lab

This is an activity to review the gearing ideas learned earlier in the course and to push the students to think how they want their dragster to perform; acceleration vs. speed.

Tower Build

This is a supplemental activity to give students more practice with building structurally sound designs. My class had tower heights ranging from 15-20cm and supported weights of up to 30 pounds.
