Instructional Material: 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).
