Demonstrating Induction with PocketLab Voyager

Submitted by PocketLab on Mon, 08/14/2017 - 17:51

PocketLab Voyager is in the middle of a coil of wire. The rest of the wire is also wrapped in a coil, and a magnet is used to induce a current through the coil/wire. The magnetic field from the coil around the Voyager is then measured by the Voyager's magnetometer. The right hand rule tell us the magnetic field from the coil will be along the z-axis of the PocketLab Voyager. In the video you can see the z-axis of the magnetic field graph (lower graph) change each time the magnet enters. Science is awesome!


PocketLab Voyager: Moment of Inertia and Conservation of Angular Momentum

Submitted by Rich on Fri, 08/11/2017 - 21:32

As shown in the image accompanying this lesson, conservation of angular momentum can be investigated using a Lazy Susan (LS), PocketLab, and a compact weight.   Voyager is mounted to the LS.  The LS is given a spin and gradually slows down from friction.   The compact weight is dropped just above the edge of the LS.  The resultant sudden decrease in angular velocity is recorded by Voyager.  The accompanying video shows all of this action.  Taking into account the moment of inertia of the LS, and

Voyager & Ozobot: Teaming Up to Study Kepler’s Law of Equal Areas

Submitted by Rich on Tue, 08/08/2017 - 19:45

Although there are a number of Web-based screen animations illustrating Kepler’s Law of Equal Areas, there are virtually no widespread physical demonstrations using actual hardware—at least not until Ozobot made the scene!  Now with Voyager and Ozobot working together as a team, the motion can be visualized and studied quantitatively

New PocketLab Voyagers and Weathers are Shipping!

Submitted by DaveBakker on Mon, 08/07/2017 - 18:50

The PocketLab office buzzing with excitement. Boxes are stacked to the ceiling with our new PocketLab Voyager and Weather parts, probes and accessories, and shipping materials. There's almost no space to walk around. Everyone is busy hand assembling and testing the new units before they ship, and each package gets a double and sometimes triple check as we sort out our shipping procedures. It's a busy time for the PocketLab team!

Voyager & Ozobot: NGSS Science and Engineering Practices Challenge

Submitted by Rich on Fri, 08/04/2017 - 21:02

This lesson provides a challenge that incorporates all eight of the Next Generation Science Standards (NGSS) science and engineering practices.  Although this lesson makes use of both Ozobot and Voyager, neither of these is required, as all data have been collected and are supplied.  Students match several geometric shapes with their corresponding angular velocity vs. time data obtained as Voyager/Ozobot travel around the shapes.  Students are also provided with angular momentum data from an unknown geometric shape and asked to sketch the shape from their analysis.

PocketLab and the Society for Women Engineers at Santa Clara University

Submitted by DaveBakker on Thu, 08/03/2017 - 18:39

We were proud to be invited to do a summer program for about 70 high school girls aspiring to be future engineers at Santa Clara University. The week long program was called GetSET (Get Science, Engineering, and Technology), was sponsored by the Society for Women Engineers and had activities ranging from programming to visiting Facebook, and a hands-on lab with PocketLab.
