Electric Separation – Hydrogen and Oxygen Up Close!

Thinking about potassium, we’re sure.

Starting in 1807, Sir Humphry Davy used electrolysis to discover a myriad of elements. He used this process to uncover what we now take for granted as potassium, sodium, barium, calcium, chlorine, and magnesium among others.

The process Davy’s used has largely remained unchanged and can be followed by you and your students using the following Electrolysis Apparatus Unit (N99-B-2637-040) found at NADA Scientific.

The electrolysis apparatus is used to demonstrate experiments in electrical charge/discharge and energy conversion. It features a main unit made of AS resin with fixed stainless steel electrodes, graduated test tubes (2), and a resin test tube holder. The compact design makes these units stackable for neat and easy storage. 

If you’re looking for a suitable power source, it can also be purchased with the GENECON12  as a set to create the entire lab experience of separating water into its component gases.

Continuously Variable Transmission (CVT) – Banned!

We know an engine can perform much more efficiently if it doesn’t need to accelerate and decelerate while switching gears. This is the purpose of the Continuously Variable Transmission (CVT) and is the reason it was banned from Formula One racing in 1994.  It’s operation is so smooth and effortless it was thought to take the sport out of that racing pastime.

However, CVT’s are still used in tractors, snowmobiles, motorcycles, go-karts, Formula 500 cars, and a host of other transportation vehicles and machines.

The uses for a CVT listed above can be easily examined and seen from the inside out using the ND11068 – Continuously Variable Transmission (CVT) Gearbox Cut-Away from NADA Scientific.  It allows you to engage the CVT through an electromagnetic clutch, forward and reverse insertion lever, primary pulley, secondary pulley, roller belt, final reduction unit, and a hydraulic command unit.  It’s mounted on a stand with wheels and is operated manually by hand crank to allow you to determine the speed and monitor safety.

Give Thanks for Direct Current!

It’s been just over 131 years since Thomas Edison’s Edison Electric Illuminating Company established the world’s first investor-owned electric utility station on Pearl Street in New York City.  On September 4, 1882, the Edison Illuminating Company switched on power to 59 customers in lower Manhattan, providing them with 110 volts of direct current (DC)!

Whether you’re a member of Team Edison or Team Tesla, we think both would agree that the GENECON12 is a fascinating tool to communicate the basics of how direct current works.

While it won’t power homes in your neighborhood, it will provide 12 volts of hand powered direct current with changing polarity depending on the direction you turn it.  The GENECON12 produces approximately 200mA of usable current and when connecting one GENECON to another or to a low power source, it will act as a motor.  That’s only one of 22 experimental uses!

Play Time at Work!

In order to acquaint the new employee’s with the company products, NADA Scientific holds “Show & Tell.” This week I was able to play with the Happy/Unhappy balls. I was handed two black balls. They looked similar and felt like they weighed the same weight; however, when I dropped them onto the table they did not react in the same manner. One, the unhappy ball, fell like a rock. I could see why it was named “unhappy”. The other, the happy ball, bounced like it was play time. I proceed to ask questions about the product, and I found myself bouncing the balls throughout the conversation. While we only spend a few minutes each week having show and tell, I find it both educational and fun!
