Day 7 - Thursday, July 13

The highlight of today was creating "troubleshooting puzzles" for the teachers at the professional development workshop. We built cars with a series of wiring mistakes and gear trains with locked and mis-meshed gears, and then we challenged the teachers to uncover all of the problems and correct them. Through this exercise, both the ELF students and the teachers gained experience in teaching others about common LEGO engineering problems.

Today we also continued to work on challenges to share with the teachers. We'll give presentations on these projects tomorrow morning.
