We can take an egg drop further by adding sensor data collection. Normally an egg drop is a “pass or fail” activity, and collecting data is difficult. With an sensor in place of the egg for trial runs, students can refine their designs with real life data.
Would you like to engage your entire science class as a group in a challenge? If so, then the "Speed of Mini HotRod: Long Track Challenge" may serve that purpose well!
In addition to automobile features that promote road safety, there has been and continues to be a great deal of work on highway features that save lives. An earlier lab entitled Crash Cushion Investigation, submitted by PocketLab, makes use of the PocketLab HotRod to investigate crash cushioning similar to that shown in Figure 1.
Most everyone enjoys a carnival! Some like the food--from cotton candy, to funnel cakes, to ice cream. Others enjoy rides such as the carousel, Ferris wheel, and bumper cars. Many like to test their skills in games like "Milk Bottle", "Balloon and Dart", and "Ring Toss". One of the most well-know skill games is "High Striker", sometimes called "Ring the Bell" or "Strongman Game". This game is commonly played by guys trying to impress girlfriends and wives with their macho strength. In this game, a large mallet is used to strike one end of a lever. Th
This lesson provides an example of how to ScratchX program PocketLab Voyager's tactile sensor as an ON/OFF switch. If you have a device such as a light bulb, motor, or robot that is under control of ScratchX, then the code in this lesson may be a starting point for you. The ScratchX program assumes that the device can be in any one of two possible states, which we will call ON and OFF.
A theremin , named after its Russian inventor in the early 1900's, is an electronic musical instrument that is controlled without any contact by the musician. Volume is controlled by moving one hand near one antenna, while pitch is controlled by moving the other hand near a second antenna. The sound is generated by a pair of high-frequency oscillators.

Hand and finger strength is vital in many aspects of life--from sports such as rock climbing to jobs including airline baggage workers. PocketLab Voyager's tactile sensor can be used to construct a very simple hand dynamometer to measure strength of a person's hands and fingers. Figure 1 shows a simple dynamometer constructed by the author. It consists of a 2" x 2" x 4" block of wood to which the PocketLab tactile sensor has been attached using removable double stick poster tape.
Do you really know how to walk or run? PocketLab's tactile pressure sensor provides for an opportunity for your students to investigate foot pressure during these activities. Improper form can ultimately lead to unwanted visits to a podiatrist. Whenever you take a step, your body places pressure on muscles, joints and tendons in your legs, knees, ankles, feet and toes. Controlling heel pressure is a key factor to prevent injuries in this regard.
Tactile pressure sensors are used for a wide variety applications including, but not limited to the following:
