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.
Come check out NADA Scientific sell hundreds of educational items ranging from small toys to heavy duty equipment. For over 25 years, we have supplied a range of products to meet the demands of the dynamic educational environment.

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!
Click on either of the pictures to learn more about the GENECON12 as well as other products from NADA Scientific. Receive a complimentary Adventures with the GENECON Activities Book ($10 Value) with your purchase of 1 or more GENECONS.

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!

Teachers enlighten and brighten us.
Today marks the occasion of an important holiday for science teachers: International Star Wars Day. The epic battles with the incongruous noise in space, the wisdom of Yoda, the painful lesson in over-hyped expectations that was ‘The Phantom Menace’ … all these and more have been inspirational for science teachers throughout the decades since the release of ‘A New Hope.’
What, you thought I was going to talk about National Teacher Appreciation Day? Actually, I am. Because what I am talking about is inspiration: for teachers, from teachers, and to teachers.
We appreciate and celebrate teachers not just because of the things they teach, but because of the ways they inspire us to think about the world in a new way. Whether it is to explore renewable energy, look at light in new ways or to embrace our inner geek, inspiration is what teachers give us.
So in turn let us give them our appreciation, not just this day or week, but as often as we are inspired. Feel free to discuss the teachers who inspired you in the comments.

This Thursday, April 22, 2010, is Earth Day. Earth Day is ‘a day designed to inspire awareness and appreciation for the Earth’s environment.’ NADA Scientific is proud to present 4 Ways to Celebrate Earth Day:
1. I’m sure you’ve heard the phrase “Reduce, Reuse, Recycle.” It is a succinct summary of what everyone should be doing everyday, not just on Earth Day. This year, highlight the ideas behind this by reusing plastic bottles to make a Tornado Tube.
2. Celebrate Earth Day by exploring it. Go for a hike or long bike ride. If you live in an urban area, take a walk in the park. Want something to do on your hike? Check out some fun activities to do in The Big Book of Nature Projects
3. Everyone still has to eat, even on Earth Day. For a fun activity that also saves on electricity, make a meal in a Solar Oven. Look around the web and you will find many creative recipes for foods ranging from sweet to savory. (Note, if you plan to make this your main meal, plan ahead. While solar ovens do not use electricity or fuel to cook, they do take time.)
4. Learn, or teach, a lesson in renewable energy. From Biomass to Wind, alternatives to fossil fuels are becoming more and more viable as energy sources. Race a hydrogen powered car or build a wind turbine to explore the technology of the future.
I hope you enjoy some of these activities, and feel free to comment with any other suggestions for Earth Day. But remember, these activities can be done any day to celebrate our amazing Earth.
