Today even the most difficult concepts seemed to come easily.

The third grade is getting to be fast and excellent builders and observers.


There has been time to go through the many different changes to learn many ideas about wheels and axles,

pneumatics, and levers,
pulleys
gears, and pulleys.



It has been a great learning experience. Now to the next school.
