Lab4Physics Classroom Edition Powered by Arbor Scientific

The Lab4Physics App is a helpful tool for teaching physics and physical science. It is a lab app for smartphones and tablets, and because of the familiar controls and friendly, easy-to-use interface, all your students can use it


The App works by using the built-in features of cell phones and tablets that convert easily to probeware, such as the accelerometer, which we will explore first.

Fig 1.  The Lab4Physics home screen.  When you open the app, there are lots of experiments you can try (which are categorized on the left) or you can go straight to the tools (right) and perform your own experiments.




If you shake the phone up and down, the accelerometer records this motion in 3D. Deleting the X and Z axis, we will now graph only the Y-vertical motion.

Fig 2.  It is easy to use the accelerometer to measure the earth’s gravity field strength.  Here the phone was held vertical then slowly turned to lay flat.  The gravity constant 9.8 m/s2 is measured.

The app allows you to zoom in, both vertically and horizontally, and slide the image around, just like a picture or map.  Because this interface is so familiar, students will already know how to do this.

Fig 3.  The phone’s Acceleration is measured in 3 dimensions, but typically you only need one.

Because the accelerometer is so easy to use, you will find yourself using it in many different applications, such as spring and pendulum experiments.  Note that when facing the phone, X is right and left, Y is up and down, and Z is toward and away.  The positive axes are right, up, and toward, which you can remember with thumb X, open fingers Y, palm-slap Z.

Fig 4.  Zoomed-in on the image of the above data.  Vertical zoom for precise amplitude measurements and horizontal zoom for precise time (period) measurements.

Fig 5.  A plastic bag is a convenient container for the phone when performing spring and pendulum experiments.  The touchscreen still works fine through the plastic.




Using the microphone, Lab4Physics can analyze the intensity and frequency of a sound that the phone records. With this device, you can see the waveform of the frequencies that the phone picked up. Use this to compare the amplitudes of loud and quiet sounds or the frequencies of a high and low pitch.  This works as an instant oscilloscope. It is also possible to measure the period as the time between peaks, it helps to zoom in for this.

Fig 6.  The Sonometer makes a measurement of the author’s whistling ability.  The period can be measured as the peak to peak time, or the Highest peak frequency can be displayed automatically by using the Intensity vs. Frequency feature.

The waveform displayed looks transverse, but the sound is a longitudinal wave.  Therefore, it is important to explain how this wave was generated.  It was the motion of the vibrating microphone that moved a small magnet that generated the electricity that became the signal displayed. The device also can calculate the frequency of the loudest part of the signal it is detecting.  This can be used to test who sings with the highest or lowest frequency or just to check the frequencies of musical instruments.

Fig 7.  A tuning fork, which is supposed to be the musical tuning standard A 440Hz, is revealed to be very nearly correct by the Lab4Physics App’s Sonometer feature.




One of the most useful features is the ability to track an object’s motion.  Utilizing the phone’s camera, film an object (usually with a ruler in the picture), and by tracking at a specific point on the object, you can follow its motion through the frames of footage.

Fig 8.  An accelerating toy car has its motion tracked through ten frames of footage generating the expected parabola of an accelerating object.

 Because the frames are equally separated by time intervals the app can turn this data into a distance vs. time graph.  From this data, it further generates the acceleration and velocity graphs.  Even a Data Table is provided so you can sort out anomalous data or analyze further.




Lab4Physics also has a speedometer which is a streamlined alternative to stopwatches.  Students can, for example, set up a series of positions and click the split button to get the individual times for when the object is at that position.  Using this, graphs are generated for position and velocity.

Fig 9. A typical Speedometer experiment. Tracking the position of a toy car through space. Changing it from going slow to fast can show up on a position vs. time graph.




Lab4Physics has lots of ready to go labs to instruct your students, or you can use them to give you ideas.  Here we explore some of the labs on waves.

Fig 10.  Left, a screenshot from the app shows the four labs on waves.  Choosing Do-Re-Mi takes us eventually to this screen, right, which shows how we will be exploring the frequency of a musical instrument.

 The labs take the students through the experiment in five or six steps.  They are self-contained and complete and let you know how much time the activity should take.

Arbor Scientific Launches Slow Motion Physics Video Contest

Slow motion video capability is an exciting new feature in the latest smartphones and it hasn’t taken long for cool new slow-motion videos to surface, especially in science.

View or Vote


Arbor Scientific has been the leader in finding cool science tools for the past 30 years that make understanding scientific principles easy, fun and exciting for today’s students. “We started this contest as way to enable science lovers like us to easily share our smartphone slow-mo videos that can remarkably demonstrate the physics of so many complex principles. Ideally we want #SlowMoPhysics to become a new free resource available to science teachers to help teach physics in a cool way” says Andrea Kelly, Marketing Manager of Arbor Scientific.

This new slow-motion competition seeks videos from teachers, students and all people who capture demonstrations of “physics” in the world! The contest will accept submissions from December 6, 2016 to January 31, 2017. Also, the public can vote on the submissions at the contest video gallery page found on

The winner(s) will be selected by Arbor Scientific based on originality, popularity and educational value by March 1, 2017 and will receive a $100 gift certificate from Arbor Scientific and the chance to be profiled via Arbor Scientific’s blog and their CoolStuff e-Newsletter mailed to over 20,000 educators.

There also is a specific Teacher Challenge!

Arbor Scientific is encouraging teachers to have their classrooms participate, and get a surprise classroom prize.  See the #SlowMoPhysics Video Contest page for further details.


Howdy Texas!

We invite you to stop by our booth #418 so that you can personally see and touch many of the “Cool tools” that we have for physics, physical science and chemistry.  We will have many products on display, but the following will be featured:

  • RSpec-Explorer – View spectra live on a PC in minutes, and experience real-time spectroscopy for a fraction of the cost of like products.
  • Pendulum Wave – A unique Arbor Scientific acrylic model which consists of a series of pendula with increasing time periods. When the nine pendula are simultaneously released, they produce the effect of a wave.
  • Forces on Inclined Plane Demonstrator – A new Arbor Scientific tool that allows teachers and students to engage directly and easily with different forces and angles on an inclined plane. If you would like to have a more in-depth introduction to our Cool Tools, we invite you to attend our workshop on Force and Motion or any of our sponsored workshops described below.
