Steve Spangler is a celebrity teacher, science toy designer, speaker, author and an Emmy award-winning television personality. Spangler is probably best known for his Mentos and Diet Coke geyser experiment that went viral in 2005 and prompted more than 1,000 related YouTube videos. Spangler is the founder of http://www.SteveSpanglerScience.com, a Denver-based company specializing in the creation of science toys, classroom science demonstrations, teacher resources and home for Spangler’s popular science experiment archive and video collection. Spangler is a frequent guest on the Ellen DeGeneres Show where he takes classroom science experiments to the extreme. Check out his pool filled with 2,500 boxes of cornstarch!

This lesson is used for students to analyse the design of a technological device that protects other devices by using or controlling static electricity (such as paint sprayers, photocopiers, lightning rods or grounding wires). I use this lesson near the beginning of the electricity unit in SNC1D1, after introducing static electricity and charging by friction, contact and induction.

In this demo, a polyethylene strip is charged by rubbing with wool. The charged strip is then used to make paper circles stand on their edges inside a Petri dish. This demo introduces students to the charging of materials by induction as opposed to charging by contact.

As the weather gets colder and dryer, you are more likely to get shocked when getting out of a car, touching a door knob, or doing laundry. Is there a way to prevent getting shocked on the car door?
In this demo, a polyethylene rod is charged by rubbing with wool. The charged rod is then used to bend a stream of water flowing from a tap.
This demo is part of the STAO grade 9/10 demo collection – a series of engaging demos and activities specifically designed with safety in mind. You’ll find the entire collection in the resources section of the STAO website. Continue reading
Watch Derek Muller of Veritassium explain the science behind the demonstration known as Kelvin’s Thunderstorm. It may not be a practical way of generating electricity but the science is very cool.
In this demo, two polyethylene strips are charged on one end by rubbing with wool. One charged strip is then mounted on an evaporating dish and the other charged strip is used to make the dish spin. Continue reading
