at 5th Grade
April 20, 2012
Various students worked on pulley projects
and
wheel and axle projects
It is hard to see the difference between single and separate axles
but it is easy to feel how different.
Some of the other students worked on gear and pulley projects.
Gear that mesh can transfer motion at distance.
Large driver and small follower will make the motion faster.
Motion can also be at right angles.
These two built the alligator WeDoTM project.
We used MIT's SCRATCH to program it.
As the real object moves toward the real gator
it moves closer on the screen.
Kiki knows the gator is very nice.
Kiss, kiss
