You have a plasma ball in your lab, now what should you do with it?
Check out this video I made to find out about demos and what you and your students can learn from each simple yet engaging demo. Most physical science standards require that students understand plasma as the fourth state of matter.
What is a plasma ball? Well, by my definition, it is a safe and engaging tool for studying high voltages in the electric field.
One sample demo is the following: The electric field can be investigated with a small neon bulb or diode. If you bring it close to the plasma ball, it will light up! There are nine more interesting demos included in the video. What are you waiting for? Just go watch it!
Arbor Scientific also featured this video on their blog and you can watch it on their YouTube channel as well. If you want to learn about the demos in writing, go read the article at the Arbor Scientific Cool Stuff blog.
