Welcome to Cuckoo Clock Toys and Gifts!
Create for yourself an engineering marvel with the UGears STEM LAB Counter. This device counts repeated actions with a click button and cylindrical numbered gears. You might see someone using a device like this at the gates of an amusement park or the entryway of a theater to count the number of people entering. This kind of counter is also a crucial part of the modern odometer, found in every car. However, with this home built model Counter, the limit to its uses is within your imagination.
The counter was first invented in ancient Greece by the mathematician and engineer Hero of Alexandria. The device is controlled by a counter button on top and a turn handle on the side. These rotate the cylindrical gears with the number 0 to 9 written on them. There are three gears, so this counter can display any number from 0 to 999. The engineering marvel of the device, great for students to learn about, is the Geneva drive that controls the gears. When counting, the drive will increment the next gear when the previous reaches 9. When you need to reset the counter, you can do so by opening the front panel and resetting manually.
This model is rated difficulty level easy and is great for ages 8 and up. It is also certified by STEM.org as an authenticated educational product for helping students learn and develop 21st century skills. For education purposes, the great thing about this model is that it can be made either with or without directions. Given directions, putting together a model like this is a great way to teach procedural direction following and how the machine works. Without directions, assembling the model is like solving a puzzle, activating critical thinking skills.
This model has plenty of fun applications, as many as you can think of. You could count how many steps it takes to get from point A to point B. You could count the number of cars that pass in front of your house in an hour. You could keep the counter on your desk and increment the counter every time a task is completed.
It is easy to build this model right out of the box. Since the details are already pre-cut, you can simply press them out of the board without any sharp cutting knives. No glue is necessary either. If you would like to personalize your Counter, you can paint the wood and add extra creative fun to assembling the device. Everything you need comes in the box, so no additional trips to the hardware or craft store are necessary. Putting together the UGears STEM LAB Counter and learning about its engineering could not be easier.
