Data collected with the LabQuest App that contains latitude and longitude information can be mapped on a computer in several ways. If you have access to Logger Pro, see How do I map GPS data collected on a LabQuest?.  Alternatively, you can fol...

Below are a list of sensors that DO NOT work with a Go!Link. For a list of sensors that do work with an Go!Link, see the Compatible Sensors tab on the Go!Link web page. The list indicates the Go!Link limitation followed by the sensors that do n...

Some of the tackle kit components included with the Structures & Materials Tester (Go Direct or LabQuest) can bend when excess force is applied. This includes the u-bolts, which will bend before the maximum rating of the force sensor/load cell (1...

Here are some things to check The Collect button in the DataQuest software will not activate until a sensor is detected. If you are using a sensor that does not auto-ID, manually set up the sensor for data collection. A connected sensor may...

One popular method is to get several shoe box-sized plastic containers and put one kind of each of your Vernier items in each (e.g., one bin for LabPros, one bin for pH sensors, and one bin for temperature). When you are doing a lab that requir...

Yes. Many current nucleic acid and protein stains are able to use blue light illumination to fluoresce and indicate the positions of fragments in gels. These stains, when bound to either nucleic acids or proteins, are generally excited in the 450 to ...

The force sensor (aka load cell) reading is affected by minor variations in motion affecting the connection between the sensor and the structure, as well as minor voltage fluctuations. Our experiment files take advantage of oversampling to minimize t...
