Water Quality with Vernier Lab Book Update

Water Quality with Vernier

After many years, we are happy to announce the second edition of Water Quality with Vernier. This updated version has many improvements that we think instructors will appreciate. This is our first book with instructions for using LabQuest with Data Matrix mode—a mode designed especially for field work. While many of the tests are familiar, they have been updated to incorporate new sensors, such as the Vernier Optical DO Probe, that have been developed since the first edition of the book.

Helpful Tips for Using the Voltage Probe in Electrochemistry Experiments

Voltage Probe

In electrochemistry, a voltaic cell is a specially prepared system in which an oxidation-reduction reaction occurs spontaneously. This spontaneous reaction produces an electrical potential that can be easily measured using a Voltage Probe. Taking advantage of this fact, students are able to quickly establish the reduction potentials of five unknown metals relative to an arbitrarily chosen metal in “Experiment 28–Establishing a Table of Reduction Potentials: Micro-Voltaic Cells” from Chemistry with Vernier.

Go Wireless® Heart Rate

Go Wireless Heart Rate

We have expanded our line of wireless sensors with the new Go Wireless Heart Rate. This affordable sensor consists of a pair of wireless hand grips that can be used to measure human heart rate with a mobile device. It is ideal for continuously monitoring heart rate before, during, and after exercise. Go Wireless Heart Rate works with iOS, Android, and LabQuest 2.

Vernier Chemistry Investigations for Use with AP* Chemistry

The College Board’s AP Chemistry Curriculum Framework has undergone significant changes, shifting the course from a more traditional, content-based model to one that is intended to support an inquiry-based model of instruction. According to the AP chemistry course overview, six labs should use an inquiry-based model of instruction.

Vernier Chemistry Investigations for Use with AP* Chemistry

Our newest lab book, Vernier Chemistry Investigations for Use with AP* Chemistry, is organized into 16 student-directed investigations using probeware that are aligned with the labs in the AP chemistry lab manual published by the College Board.

USB Digital Microscope

USB Digital Microscope

The Vernier Biology Department has been on a continuous quest to uncover new, exciting, and affordable tools for biology teachers. Our newest offering is the USB Digital Microscope that works on Chromebooks and with Logger Pro software on a computer. This 5 MP digital microscope connects to a computer or Chromebook via USB, giving you a live image that is very similar to what you would see with a traditional dissection microscope. It features a 10–300X lens with manual focus and an adjustable LED light source. In addition to capturing still images, you are able to record short videos and time lapse sequences.

Included with the USB Digital Microscope is an adjustable stand that, in conjunction with the manual focus, allows you to change the plane of view you are looking at on the screen. With a fast response time and high resolution, you can get very clear images that are easy to display, save, and place directly into lab reports. This new tool offers a world of possibilities for you and your students to explore.

Arduino and Vernier Sensors

Arduino Sparkfun Redboard

We recently updated the Arduino section of our website. It has instructional material to lead students through a short course on Arduino terminology, an introduction to how sensors work, and sample projects. We have also posted sample code to read from over 80 Vernier sensors, which can be connected via the Vernier Arduino Interface Shield. This includes recent updates to the code to auto-ID on any Vernier BTA (analog) sensor, run a servo motor, and control a Vernier Digital Control Unit. We also have several sample projects that students will find interesting, including a laser pointer aimed with a servo motor, alarm systems based on motion detection, and a system to drive a pendulum with an electromagnet to keep it swinging indefinitely.

Engineering Tests with the Vernier Structures and Materials Tester

Vernier Structures and Materials Tester

Years ago, Dave Vernier loved to run bridge building competitions while teaching physics in Hillsboro, Oregon. The students became more engaged with these hands-on activities, and competition often brought out their best efforts. The only part of the process that Dave did not relish was testing all of the bridges his students made. Borrowing weights from the PE teacher to hang off the bridges, pouring sand into a bucket suspended under the bridges, and rigging up a scissor jack to apply a load to the structures all worked but required a lot of effort and were time-consuming! Dave attributes this activity to his initial exploration of electronic sensors and the beginnings of Vernier Software & Technology.

Lab Instructions Written for Motion Encoder System

Motion Encoder data for an inelastic collision of two carts
Velocities of two Motion Encoder Carts colliding inelastically

Last year we introduced the Motion Encoder System, and many instructors are now using them with their physics classes. Now, the five experiments from Physics with Vernier that use the Vernier Dynamics System have been updated for use with the Motion Encoder System. These experiments include:

  • Experiment 2, Back and Forth Motion
  • Experiment 3, Cart on a Ramp
  • Experiment 4, Determining g on an Incline
  • Experiment 18, Momentum, Energy, and Collisions
  • Experiment 19, Impulse and Momentum

If you already own a copy of Physics with Vernier and would like the updated files for the student pages for the five experiments, email us at physics@vernier.com
