Wireless static charge sensor lets users explore electrostatics
The new Go Direct Static Charge sensor, says the company, is designed to engage high school- and college-level students in hands-on physics and data collection. Unlike a traditional electroscope, the completely wireless sensor offers a means for quantitative measurement and analysis of positive and negative charges of objects that would not be possible in a traditional lab, such as measuring the charge on a balloon.
“With Go Direct Static Charge students can easily and accurately measure and analyze static charges,” says John Wheeler, CEO of Vernier Software & Technology. “The sensor’s enhanced capabilities expand upon our wired version, and its pricing at under $100 makes it an affordable addition to any physics classroom or lab.”
Like all of the company’s Go Direct sensors, the Go Direct Static Charge connects via Bluetooth to any mobile device, Chromebook, or computer with either the Vernier Graphical Analysis or the Vernier Graphical Analysis Pro apps. Students can use these apps to visualize charge readings in real time and immediately analyze experimental data, which can also be exported to other applications.
The sensor, which features a long-lasting rechargeable battery for wireless use, can also be connected to devices via USB. This provides educators the opportunity to choose any location for learning — whether it is in the traditional classroom, lab, at home, or even outdoors.
The Go Direct Static Charge can be coupled with the company’s Electrostatics Kit to engage students in new, deeper levels of experimentation. The kit features a variety of items that allow students to perform a range of electrostatics experiments, including the use of a Faraday cage and pail, quantitative and qualitative measurements of charges, charging by friction, charging by contact, and charging by induction.
The sensor additionally supports a number of physics experiments created by the company, including “Charge and Charge Models,” “Coulomb’s Law,” and “Electrostatics.”
