Vernier Promotes Volunteerism

Collage of photos from Vernier's volunteer fair

Vernier hosted its first employee volunteer fair during National Volunteer Week. Local non-profit organizations committed to animal welfare, the arts, education, health, and human services graciously attended Tuesday’s fair.

The goal of the fair was to motivate and excite Vernier employees to help improve our community through volunteer work. Vernier employees are given a dedicated monthly amount of paid volunteers hours. These hours have been used with wonderful organizations such as Habitat for Humanity, Meals on Wheels, and the Audubon Society of Portland.

Motion Encoder Receives Rave Review in UK Science Publication

Vernier Dynamics Cart and Track System with Motion Encoder

In a recent review in its publication, School Science Review, the Association for Science Education (ASE) praises our Dynamics Cart and Track System with Motion Encoder for its ability to produce noise-free, position-time data. The article also highlights the option to analyze the data with our Logger Pro data-collection software or LabQuest App, both of which are “excellent and very easy to use.”

The Dynamics Cart and Track System with Motion Encoder (formerly known as the Motion Encoder System), recommended for high school and college classrooms, is a complete, revolutionary dynamics system with carts, track, and associated hardware, including a new optical motion encoder to record cart position. Recent updates to the system include an entirely redesigned cart that makes it easier than ever to attach a sensor or increase mass. The plunger cart also features a super-elastic trigger button that allows for a host of new collision types.

School Science Review—a quarterly periodical distributed to ASE members, university libraries, and education centers worldwide—featured the review in its March 2016 edition.

Superelastic Collisions with the New Vernier Dynamics Cart and Track System with Motion Encoder

Vernier Motion Encoder Cart and Plunger Cart on a Dynamics Track

Dynamics experiments are a core part of many physics courses, and low-friction carts and tracks have long been a popular tool for use with Vernier sensors. Based on customer feedback, we have redesigned our carts and accessories, making a good system even better. Renamed the Dynamics Cart and Track System, the set is available with or without our unique Motion Encoder System, and with either a 1.2 or 2.2 meter track. Additional accessories, such as a pulley and pulley bracket, are also now included—all for an even lower price.

The carts have been redesigned from the axles up. It is much easier to attach sensors and masses to the carts, and, to facilitate classroom discussions, the carts now come in two colors. A new, triggered‑release mode for the spring plunger allows students to set up a superelastic collision between two carts—a collision where the kinetic energy increases. Such a collision still conserves momentum because the plunger spring force is internal to the two-cart system.

To demonstrate the superelastic collision feature, we started with a standard Vernier Dynamics Cart and Track System with Motion Encoder and Long Track, which includes one plunger cart and one encoder cart. We used the optional Motion Encoder Upgrade Kit to turn the plunger cart into an encoder cart. This gave us the ability to track both carts simultaneously, providing excellent position and velocity measurements.

In Logger Pro, we configured the Motion Encoder so that the carts shared the same coordinate system, with the same zero position and positive direction. We started the experiment with the plunger cart at rest, and rolled the plain cart into the plunger cart. On impact, the carts explosively moved apart, with the plain cart reversing direction. The position graph shows the motion clearly, with the cart represented by the blue line rolling into, and then away from, the other cart. Note the complete absence of spikes or other noise in the graph traces, made possible by the Motion Encoder System.

The cart masses were approximately the same (see table). The total kinetic energy of the two-cart system changed by more than a factor of four. The total momentum was essentially unchanged, as expected, because the spring force was internal to the system.

Plain cart* Plunger cart Total momentum Total kinetic energy
Velocity before (m/s) 0.541 0.000
Momentum before (kg m/s) 0.173 0.000 0.173
Kinetic energy before (J) 0.047 0.000 0.047
Velocity after (m/s) –0.514 1.028
Momentum after (kg m/s) –0.164 0.334 0.169
Kinetic energy after (J) 0.042 0.171 0.214
  • * Plain cart mass: 0.3198 kg
  • † Plunger cart mass: 0.3245 kg

In addition to studying superelastic collisions, have students use the Dynamics Cart and Track System to investigate various kinds of collisions, including elastic collisions using magnets as a nearly energy lossless bumper, lossy inelastic collisions using a spring plunger, and totally inelastic collisions using hook-and-pile tabs.

  • A Perspective on Motion Sensors and Free Fall

    Derrick E. Boucher; American Journal of Physics. 2015, 83, 948–951.

    Those of you who use Motion Detectors frequently, especially for studying free-falling objects, may find this article enlightening. It is a detailed study of how the horizontal position of the object relative to the Motion Detector can introduce an error in measured accelerations. The errors can make the measured accelerations slightly high.

    A smartphone is used to enhance a classic physics experiment. The phone is used as the weight on one side of an Atwood machine, and it also measures the acceleration. Our Graphical Analysis app is used to graph and analyze the data. The authors demonstrate that you can nicely show a linear relationship between the mass difference and vertical acceleration.

  • Turn Your Smartphone into a Science Laboratory

    Rebecca Vieyra; Chrystian Vieyra; Philippe Jeanjacquot; Arturo Marti; and Martín Monteiro; The Science Teacher. 2015, 82, 32–39.

    This article explains how to use the accelerometers in your smartphone to do a number of great physics experiments, including measuring the acceleration due to gravity, studying acceleration in an elevator, or measuring centripetal acceleration on a turntable. The best way to analyze the data collected this way is to use our Graphical Analysis for iOS or Android. Both apps are free downloads.

Build a Robot with a Green Thumb

What unique, creative, and interesting solutions do you think your students could devise when presented with this challenge?

Your challenge is to design and build a sensor-controlled watering system for a potted houseplant using your EV3 robotics kit. Your device should automatically water the plant when the soil is too dry but also stop when the soil is sufficiently wet. You will use a Vernier Soil Moisture Sensor to monitor the moisture level of your plant’s soil. The soil will be considered “too dry” when the moisture level falls below 20%, and sufficiently “wet” when the moisture level rises above 28%.

The programming and constructing of a sample solution for this challenge are clearly outlined in the teacher’s section of our Vernier Engineering Projects with LEGO® MINDSTORMS® Education EV3 lab book. In our sample solution, we attach a LEGO® pneumatic pump to a LEGO® motor. A clear plastic water bottle is equipped with a 2-hole stopper, and tubing attaches from the bottle to the pump and from the bottle to the plant. We program this robot using a MINDSTORMS® Loop block that continuously monitors the reading from the Soil Moisture Sensor. If the reading is within the range, the robot does nothing; but if it falls below the threshold value, the program activates the motor to pump air into the bottle and push water out to the plant. The program waits to allow the water to percolate and loops back to monitor the sensor reading again.

When presenting this challenge to your students, one option is to share some, or all, of the sample solution with them. Another option is to have your students fully take on the challenge by allowing them to come up with their own distinct solution. This will undoubtedly lead to some truly imaginative, interesting, and fun ways to transport, carry, or splash water on a thirsty plant. For students who finish early or who want to pursue an independent project, the book also provides project extension ideas. In one project extension, a robot monitors the amount of light that the plant receives. If the light is too low, the robot must increase the light or warn the plant owner.

A real-world challenge like this introduces your students to the engineering design process. Students learn about robotics and programming, delve deeper into scientific principles, discover how sensors work, and learn how to solve problems as a team.
