5th grade helpers
April 20, 2007
A winch can be powered with the electricty in capacitor.
These 5th graders practiced building LEGO projects using eLab sets.
The car can be run with electricity that is saved up in a capacitor.
The electricity was made by turning a motor.
This gear train and a rubberband can also power the car.
These 5th graders will be helpers next week for the 3rd grade build with mini sets.
