"pathway PLASTICS, INC."

Used in ECG, EMG, and EOG experiments, these electrodes allow the attachment of three-lead electrode cables or individual electrode lead wires onto the snap connector. They come pregelled with self-adhesive hypoallergenic foam.

The programmable robotic vehicle that drives conceptual curiosity in math, science and coding.

This project kit makes coding and engineering design accessible to students in the classroom.

An economical digital stroboscope.

Lessons in Optics and Light in the Palm of Your Hand Colorfully illustrate additive and subtractive color mixing, color transmission, absorption and filtering of the different wavelengths of light with this set of primary and secondary color mixing paddles. You can also use the diffraction gratings in this set to view spectra from different light sources. Show students how a spectroscope, colored lights, and even polarized sunglasses work with the contents of this set.

NOTICE: CONFORMS TO ASTM D-4236.


WARNING: CHOKING HAZARD–Small Parts. Not for children under 3 yrs.

Demonstrate the Stirling Design External Combustion Engine with our 18×11 cm working model. The Stirling engine currently is being re-examined as a practical source of power because of its adaptability to almost any fuel. First produced in the 1800’s as a non-electric fan and an automatic hot air water pump, the engine soon became obsolete due to its lack of sufficient power when compared to the newly developed combustion engine. Any fuel can be used with our model, but denatured alcohol is suggested for clean operation.

Perfect for demonstrating anchoring as well as connectivity, if one student puts a finger on one contact, another student puts a finger on the second contact and both then hold hands, the ball will light up.

The properties of radioactivity and the concept of half-life determination can be difficult subjects for students to fully understand.
