The PocketLab TurboTrack

The TurboTrack is a physics playground for building roller coasters, ramps, and crash barriers to do hands-on science experiments. Using Hot Wheels track and PocketLab track connectors, the TurboTrack allows students to creatively investigate classic concepts in force, motion, energy, momentum, engineering, and more. 

PocketLab TurboTrack Lessons

With a PocketLab Voyager and a PocketLab TurboTrack you can do dozens of experiments and science activities. The upcoming beta release of PocketLab's new Science Notebook software will have digital downloads of specific TurboTrack NGSS aligned activities. The PocketLab TurboTrack also provides you with eveyrthing you need for these Pocketlab lessons on our Educator's page:

PocketLab TurboTrack Getting Started Guide

An instruction booklet is included in every PocketLab TurboTrack kit. Below is a digital version. 

PocketLab TurboTrack Getting Started Guide

HotRod Cart and Bumper Set

Assembling the HotRod

 

  • Press the ball bearings into the HotRod axles
  • Each of the three bumper types will press fit into the front of the HotRod
  • Assemble the Adjustable Mass Hitch, screw the nylon rod into the threaded insert of the HotRod and add washers/mass to the rod. 
  • To add pulling/hanging weight to the HotRod, tie a string to HotRod loop. Tie the other end of the string to the nylon eye bolt. Add washers to the thread of the eyebolt and use the nylon nut to keep them in place.

 

Assembling the HotRod

 

 Inelastic Bumper

  1. Press fit the solid, inelastic bumper into both HotRods.
  2. Place the hook Velcro dot on one circuluar indent of the solid bumper and place the loop Velcro dot on the other circular indent. 
  3. Repeat this step on the second HotRod. 
  4. When the two HotRods collide, the Velcro dots should match up in opposite pairs and stick together for an inelastic collision. 


Elastic Bumper

  1. Press fit the spring, elastic bumpers into both HotRods
  2. When the two HotRods collide, the spring in the bumpers will cause an elastic collision. 


Magnetic Bumper

  1. Press fit the small, magnetic bumpers into both HotRods. 
  2. Press fit each magnetic bumper into a magnet (see diagram above). 
  3. You can connect more magnets to the original magnet to increase the magnetic field strength. 
  4. Collide the two HotRods. They will either repel each other or attract and stick together. You can flip the magnets to change what they will do. 
  5. Add magnets to to the Magnetic/Stopper Track Connector. You can now use the magnets on the connector and the magnets on the bumper to launch the HotRod along the track using the force between the magnetic fields. 

 

How to Collect Data with the HotRod

  • Place a PocketLab Voyager sensor in the center slot of the HotRod. 
  • The HotRod fits in the Hot Wheels track from this kit or can roll along any surface. 


Rangefinder: You can measure the position anve velocity of the HotRod. Place a large flat surface, like a wall, card, or texbook in the line-of-sight of the sensor so that the sensor can measure it's relative position ot the object. 

HotRod with Rangefinder

Acceleration: You can use the acceleration function to measure motion and related forces. For example, you can mesure the acceleration and force of a collision as the HotRod hits a crash barrier. 

PocketLab HotRod Acceleration

Magnetic Field: You can set up magnetic timing gates along the track to measure the time interval it takes for the HotRod to travel over a known distance. You can use this setup to analyze roller coasters or conduct races like a Pinewood Derby.

Track and Track Connectors

There are two types of track connectors in the PocketLab TurboTrack Kit: regular connectors (blue) and specialty connectors (green). Each connector can be inserted into the bottom of the orange Hot Wheels track. The regular connectors simply connect two pieces of track. The specialty connectors allow for interesting and unique physics experiment. 

Ramp Connector (x1): Allows you to elevate your track so your HotRod can travel downhill. Perect for a number of force and motion, energy, and collision experiments. 

Ramp Connector

Pulley Connector (x2): Place this piece at the end of a Hot Wheels track and position it at the end of a table. The pulley is now in perfect position for a Half-Atwood experiment. Tie one end of the string to the HotRod and the other to the Adjustable Hanging Weight (eyebolt with washers). Thread the string over the pulley and release the hanging weight to pull the cart. Try adding mass to the hanging weight and to the cart to see hwo the acceleration changes. 

Pulley Connector

Combined Ramp and Pulley Connector: You can combine the Ramp Connector and the Pulley Connector to create an elevated pulley system. Connect a small piece of Hot Wheels track (you can cut a piece down with scissors) at the higher end of the Ramp Connector. Then, connect the Pulley Connector on the other side of the small piece of Hot Wheels track. You now have an elevated pulley system. See the image for more details. 

Elevated Pulley System

Rubber Band Launcher Connector (x1) - Tie each end of the rubber band to the two polls on the outside of the connector. Use the rubber band to launch the HotRod down the track. Change the amount of elastic potential energy in the rubber band and see how the velocity of the HotRod changes.

Rubber band launcher

Magnet/Stopper Connector (x1) - This piece has two functions. 1. Place the connector at the end of a track to act as a solid stopper for the HotRod. This is good for comparing bumper collisions or crash cushions. 2. Press fit the magnet onto the connector. Add a magnet to the Magnetic Bumper on the HotRod. Align the magnets so they repel each other. Pull the HotRod close to the connector and release. The HotRod will zoom across the track from the forces in the magnetic fields. Add magnets to see how the velocity and distance traveled changes.

Magnet/Stopper Connecter

All of the specialty connectors and HotRods are 3D printed. If you have access to a 3D printer, you can print more or customize your own. Find all of the 3D printer files on our PocketLab Thingiverse Page.
