How to Collect Data from a Fidget Spinner and a Photogate

By Dave Vernier

Like most people, I have heard the buzz about “fidget spinners”, so I could not resist buying one and taking some data with it. Here is a graph of data collected using Logger Pro, LabQuest Mini, and a Photogate.

To set up the experiment, I placed the fidget spinner on a LabQuest Mini so that the spokes trigger the photogate as the spinner spins.

I opened the Pendulum Timer.cmbl file found in Experiment Files > Probes & Sensors > Photogates, which is included with every copy of Logger Pro. I chose the pendulum experiment file because I wanted to measure the time from the leading edge of one of the three spokes to the leading edge of the next spoke and wanted to skip the hole on each spoke.

The graph shows the period, which in this case is proportional to the inverse of the angular speed of the spinner.

Other things you could graph:

• The angular speed of the spinner as a function of time—use that to determine the angular acceleration of the spinner to estimate how long it will spin from any starting speed.
• Peak speeds as you start the spinner with different techniques—what technique gives the highest angular velocity?

There are lots of good discussion of the science of fidget spinners on the internet. Here are two articles by Rhett Allain, author of Geek Physics, and a 3D-printed photogate mount Steve Dickie designed for collecting data from fidget spinners.

• Let’s Explore the Physics of Rotational Motion with a Fidget Spinner
  Rhett Allain measures the moment of inertia of a spinner using a Vernier Rotary Motion Sensor.
• Want to Know How Long a Fidget Spinner Spins? Get a Laser and Some Physics
  Rhett Allain measures the angular acceleration of a spinner using a laser and a light sensor as a sort of home-made photogate.

Vernier in the Journals (Spring 2017)

• More than Meets the Eye – Infrared Cameras in Open-Ended University Thermodynamics Labs

  Emil Melander, Jesper Haglund, Matthias Weiszflog, and Staffan Andersson; Uppsala University, Sweden, The Physics Teacher, Vol. 54, No. 9, December 2016.

  This article shows the advantages of using IR cameras and explains five laboratory assignments to have your students investigate. While the authors used IR cameras costing between $500 and $1500, we think these topics can be investigated with our FLIR ONE^™ camera for less than half the price. Also, our free iOS app, Thermal Analysis^™, would do a great job on the analysis.

• Video Analysis on Tablet Computers to Investigate Effects of Air Resistance

  Sebastian Becker, Pascal Klein, and Jochen Kuhn; University of Kaiserslautern, Germany, The Physics Teacher, Vol. 54, No. 7, October 2016.

  The authors use video analysis and our Graphical Analysis for iOS to study falling coffee filters and terminal velocity. They demonstrate it is possible to show that the square of the terminal velocity is proportional to the mass of the falling object.

• The Physics of Juggling a Spinning Ping-Pong Ball

  Ralf Widenhorn; Portland State University, American Journal of Physics, Volume 84, No 12, page 936, December 2016.

  Dr. Widenhorn does a thorough analysis of the act of juggling a ping-pong ball by using precise paddle angle and ball spin. He uses Logger Pro video analysis and our Dual-Range Force Sensor to measure the friction force between the ball and the paddle.

• Titration and HPLC Characterization of Kombucha Fermentation: A Laboratory Experiment in Food Analysis

  Breanna Miranda, Nicole M. Lawton, Sean R. Tachibana, Natasja A. Swartz, and W. Paige Hall; J. Chem. Educ., 2016, 93, 1770–1775.

  The authors describe an experiment performed by their students to determine the fermentation kinetics of kombucha tea over a 21-day process. As the tea is fermenting, acetic acid is forming. Students took samples of fermenting kombucha every 2–4 days and titrated them with standardized 0.1 M sodium hydroxide solution using the Vernier pH Sensor and Logger Pro software. The class data were then shared in a Google Doc and a plot of total acid content as a function of fermentation time was produced.

• Kinetic Explorations of the Candy-Cola Soda Geyser

  Trevor P. T. Sims and Thomas S. Kuntzleman; J. Chem. Educ., 2016, 93, 1809–1813.

  The physical and chemical concepts and processes involving change in CO₂ concentration, mass, and pH as they apply to the NISD (nucleation-induced soda degassing) of carbonated soft drinks with Mentos^® candy are studied. The author and his students carried out numerous experiments to set up and monitor these changes using a Vernier CO₂ Gas Sensor, an OHAUS^® balance using Logger Pro software, and a pH sensor. Arrhenius plots were also done to determine the activation energy, E_a, for the change.

• Speed of Sound in Gases Measured by in Situ Generated White Noise

  Michael J. DeLomba, Michael D. Hernandez, and John J. Stankus; J. Chem. Educ., 2016, 93, 1961–1964.

  The authors present a student experiment to measure the speed of sound in various common gases as they generate white noise inside an acoustic tube. They mounted a Vernier Microphone to a sliding adapter on the side of their PVC tubular resonator. Then, data were collected using Vernier LabQuest 2. Fourier transform analysis was done using LabQuest 2 and after data were imported into Logger Pro software on computers. The results indicate a much lower percent error for the speed of sound than during experiments done in 2014 using a phase comparison technique that used a single frequency.

• Measuring CO₂: Students Learn Firsthand How Thawing Permafrost Adds to Global Warming

  Bruce Taterka and Rose M. Cory; The Science Teacher, 2016, 83(9), 29-35.

  The authors present an experiment for students to explore the phenomenon that thawing permafrost contributes to global warming due to carbon dioxide release. Students first measure the rate of cellular respiration of microbes in thawing permafrost or garden soil using a CO₂ Gas Sensor. Students then go into the field to carry out their own investigation of carbon flux using the CO₂ Gas Sensor in both terrestrial and aquatic environments.

• The Microscopic World of Diatoms

  Molly Sultany and Rebecca Bixby; The Science Teacher, 2016, 83(8), 55–63.

  This article describes a class investigation exploring the link between diatom populations and fresh water quality. Students measure water quality data at a variety of locations while also collecting diatom samples. The diatoms are processed, visualized, and classified. Students then correlate the diatoms present with different levels of water quality at each site.

• Measuring Metabolism: Examining the Effects of Temperature on the Metabolic Rates of Beetles

  Angela Chapman, Aaron Chila, Tracy McAllister, and Victor Aguilar; The Science Teacher, 2016, 83(7), 55–60.

  This article describes a laboratory activity in which students determine the effect of temperature on the metabolic rates of bess beetles. Using a CO₂ Gas Sensor, students measure the production of CO₂ from beetles at 4°C, 25°C, and 32°C. From this data, students then mathematically determine the metabolic rate of the beetles.

• “Greening” a Familiar General Chemistry Experiment: Coffee Cup Calorimetry to Determine the Enthalpy of Neutralization of an Acid-Base Reaction and the Specific Heat Capacity of Metals

  A. M. R. P. Bopegedera and K. Nishanthi R. Perera; J. Chem. Educ., Articles ASAP (As Soon As Publishable).

  The authors investigate the use of paper cup calorimeters to replace polysteyrene foam and a measure to reduce the impact on landfills and the environment. Experiments tested were heat of neutralization of acids and bases and heat capacity of metals. They suggest that polysteyrene foam could also be replaced in experiments such as heat of sublimation of dry ice, heat of decomposition of hydrogen peroxide, heat of formation of magnesium oxide, and other chemical and physical changes traditionally involving constant pressure calorimeters that use polysteyrene foam cups. Data were collected with Vernier Stainless Steel Temperature Probes interfaced to a computer through LabQuest 2. Their results were comparable to those they tested side by side with polysteyrene foam and concluded that paper cups were a good alternative.

• Naked-Eye Detection of Reversible Protein Folding and Unfolding in Aqueous Solution

  Tess M. Carlson, Kevin W. Lam, Carol W. Lam, Jimmy Z. He, James H. Maynard, and Silvia Cavagnero; J. Chem. Educ., 2017, 94, 350–355.

  The authors describe a demonstration to help students with the concept of folding and unfolding proteins. They varied the pH, temperature, and cosolutes to see how the fluorescence of bovine serum albumin (BSA) in the presence of 8-anilino-1-naphthalenesulfonate (ASA) changes. They used Vernier pH Sensors and Logger Pro software to monitor the effect of pH on the fluorescence, noting that at pH of 6.5 to 7.5 the solutions fluoresce brightly. Fluorescence dims considerably over pH of 10 and below pH of 3.5.

• Improving Student Results in the Crystal Violet Chemical Kinetics Experiment

  Nathanael Kazmierczak and Douglas A. Vander Griend;J. Chem. Educ., 2017, 94, 61–66.

  Many high school chemistry teachers use this familiar reaction to help teach chemical kinetics. The authors of this article provide some insight and suggestions on how to minimize or avoid common errors students make as a result of chemical flooding, solution concentration errors, signal processing errors (which the authors noted was reduced if Logger Pro was used to process the data), spectrometer limitations, and interference from particulates formed by the reaction of OH^– and crystal violet. The authors did most of the experimental work for this article using a Vernier SpectroVis Plus Spectrophotometer and Logger Pro software. They said that for data analysis they preferred Logger Pro over Excel.
