When we update our lab books, we review all the experiments. Occasionally, we revise experiments to fix errors or remove equipment that can present an unnecessary hazard to students.
In 2017, when we released the 4th editions of some of our lab book...
There are a number of items to check, in this order, before we conclude the balance needs to be returned for repair/replacement. After completing each item, measure a solid object with a known mass.
1. Make sure the balance pan is not locked. OHAU...
This article refers to the Go Direct® 3-Axis Magnetic Field Sensor (GDX-3MG)
For information about the Magnetic Field Sensor (MG-BTA), see Magnetic Field Sensor Troubleshooting and FAQs
The Go Direct 3-Axis Magnetic Field Sensor has two range...
The Vernier UVA and UVB Sensors respond to specific regions of the electromagnetic spectrum. The wavelength region from 320 to 400 nm is commonly called UVA radiation, and 280 to 320 nm is called UVB radiation. Wavelengths shorter than 280 nm fall in...
The Charge Sensor (CRG-BTA) contains several capacitors which ideally should maintain a constant state when the test leads of the sensor are in electrostatic equilibrium. However, environmental conditions such as local humidity, nearby static charges...
KidWind simpleGEN (KW-SGEN) and GENPack (KW-GP) are both kits to allow students to make a basic AC generator.
Short version:
The SimpleGEN is simpler and we recommend it for for Middle School, High School, and College.
We recommend the more adva...
Certain dynamics cart products include a packet of Anti-Roll Pegs. The peg prevents the cart from rolling when the cart is placed on a near-horizontal surface. For example, a cart placed on a lab table will not roll and fall to the floor. However, wh...
This TIL refers to the Dual-Range Force Sensor (DFS-BTA) and Go Direct® Force and Acceleration Sensor (GDX-FOR)
Small parts and accessories associated with force sensors can be ordered as:
Replacement Rod, 5 inch (ACC-ROD)
Dual-Range Force...
The UV Index (or UVI) was originally created as a predictive tool for the public to get a sense as to how intense the UV rays from sunlight will be. The US National Weather Service model takes into account the predicted filtering from the ozone layer...
Due to the simple nature of the sensor, the ±10 V Voltage Probe (VP-BTA) may not read 0 V when the leads of the sensor are not connected to anything. While not desirable, this is expected behavior for this sensor. The value you get depends on which...
