Set 2 Educational Cogbox - Stainless Steel Axle Pegs
Set 2 has a large base measuring 20" by 20" and is ideal for introducing a number of important principles relative to simple machines and gears. This educational tool is intended for 1st through 4th grade students. The primary goal of Set 2 is to give the student an appreciation of gears through play. The gears may be moved around on a matrix board, 1000's of combinations being possible. As the student manipulates the gears a basic understanding of gears follows.
The gears are made from solid cherry hardwood and the base from laminated birch hardwood. The top of the gears have a tough lacquer finish while the sliding surfaces are finished in a non-toxic low friction mineral oil. The base is 1" thick laminated birch hardwood with 20 solid cherry gears included. Set 2 features eight large 24 teeth gears and twelve smaller 12 tooth gears are included. The axle pins are made from solid polished stainless steel. The pins are retained in the gears via a clip - no small loose parts. Two of the gears have cranks enabling students to work as a team. The base may be rejuvenated after years of service by just rubbing with 220 grit paper and reapplying food grade mineral oil. An instruction sheet is included and an activity guide is also available.
Set 3 - Gears and Pulleys
Cogworks Set 3 provides the necessary spark to get middle and high school students enthused about science and physics. Set3 is one of the new wave of tools being used to reinvigorate American school science education. Unlike Set2 , Set3 features gears & pulleys that can be stacked to create more complex mechanical designs.
Set 3's unique design features a 14" by 12" high quality matrix board making a sturdy construction platform. The structure is essentially a three dimensional mechanical artistic canvas, ready to receive creative mechanical exploration.
Set 4 - Gears and Pulleys
Cogworks Set4 provides the necessary spark to get middle and high school students enthused about simple and complex machines.
Set 4's unique design features include a 20" by 20" rectangular matrix board with a plethora of tapped insert holes. Set 4 includes all the parts listed in the Set4 kit list tabulated below. Please see the Set10 description for a full explanation of the Cogworks stacked pulley/gear drive system.
Set 4 has a great sampling of pulleys, gears and hardware, it comes packaged with the mechanical arrangement shown right. The arrangement features an interesting design featuring two sub gearboxes, idler pulleys and belt systems. We call this as delivered machine "Discovery". read more...
Set 5 - Gears, Pulleys and Machines
Set 5 includes all the parts in Set 4 and much more. Set 5 comes in a 2 sided hardwood storage case. Everything packs away at the end of he class allowing a parts count. Set 5 features attachments which allow the Set 4/Set 5 matrix base to be mounted vertically. Extension torque bars allow mechanical action to take place outside of the matrix board. Set 5 features a wooden parts tray to keep all small pieces in order.read more...
