Gearing Game

This web-based Gearing Game is a fun way to help students visualize the interaction of gears. Thanks to Mac Jones at Reeve's MS in Olympia, WA for this link.

LEGO 100+ Gear Calculator Video

This YouTube Video tells the story of an ancient Greek celestial calculation machine using precision gearing and a Lego implementation of the same device. It uses 1,500 parts and 110 gears to recreate the Greek invention. This is a great supplement to the Advanced Gearing lesson as it shows how the Greeks used compound gearing to do complex math.

Advanced Gearing: Complex and Compound Gear Trains

The attached Advanced Gearing PowerPoint presentation extends the basic gearing lesson and introduces complex and compound gearing.  A compound gearing challenge is also included.

Getting in Gear

The attached PowerPoint presentation introduces concpets around gearing for robot design.

Move Until Sound_Alt_Task

The attached Word file is an Alternative Instructional resource from Rich Bakala (Jefferson MS, Olympia, WA) which emphasizes written communication skills through a "Project Packet", as well as measurement and geometry skills as students lay out their own boards and provide geometric calculations for 3 extended challenges.

Move Until Sound

Have students work through the "Movie until Sound"  video lesson from the "Behaviors" page in "NXT Video Trainer 2.0" from Carnegie Mellon University's Robotics Academy.

Move until Dark_Ext_Colored_Ball

The attached Colored Ball Challenge requires students to pull together all the  nuances from the skills learned so far with the "Moving Straight" and "Wait Until Dark" lessons . The attached Photo shows the board layout, where the near 4x4 is flat and the far 4x4 is slightly inclined. Students will need to build a funnel-like attachment to gather the ball. The attached ColorBall NXT-G program file is a sample solution (see comments in program for explanation).
