I got to watch the entire presentation yesterday. Absolutely fascinating!
Lucid presentation of complex ideas. The theme (Pythogoras theorem) would be
attractive to both teachers and students.
The sine interpolation may pose cognitive hurdle to some middle schoolers.
Teachers could subsitute this with a lead in from the circling car project. If
the car is placed in a playfield, the car's x or y tile is a good candidate to
use in interpolation. The 'turn by' tile will tweak the speed while 'forward
by' will influence the range.
The video "Connections (Episode 4 - Faith in Numbers)" contains a scene where
the rotary motion of a water wheel is transformed into multiple types of
motion to drive various machinery during early days of industrial revolution
in Europe.
Thanks, Bert and Steve,
Subbu
