  • Blue Planet Globe
    Blue Planet Globe - Voyager Model (ships via motor freight at additional charge) NON RETURNABLE

    This 16" globe, with its internal illumination, simulates the Earth's daily rotation and seasonal changes within a six minute cycle. The terminator is clearly visible separating daylight and darkness with particular attention to the illumination of the Polar regions, the current position of the sun and the significance of the Arctic and Antarctic Circles. A smoked acrylic box aids in viewing the simulation by shielding against distracting...

  • Radiation Cans Pkg/2
    Radiation Cans, pack of 2

    Investigate the absorption and radiation of energy on different surfaces. Students fill both cans with water and place a thermometer in each. They then turn on light at 10cm distance and observe how temperatures respond differently in the black can and silver can. In a reverse experiment, the rates of cooling can be determined after the light is turned off.

  • Tangent Galvanometer
    Tangent Galvanometer

    To investigate the magnitude and direction of the magnetic field produced by a current carrying conductor, 305 cm of wire are wound on the non-magnetic stand of sturdy design. This can also be used to determine the magnitude and direction of the horizontal component of the Earth's magnetic field.

  • Secchi Disc
    Secchi Disc

    This 20 cm ABS plastic disk is weighted and supplied with a 14 m line. When lowered in a water column until the pattern is no longer distinguishable, measurement of the retrieved line gives the depth to which light can penetrate in support of biological activity.

  • Wind Powered Generator
    Wind Powered Generator

    Six fully adjustable vanes describe a 36-cm diameter circle and are coupled to the generator through a 4:1 drive train in this unit designed to study the interrelationship of aerodynamics, motion, and electrical power production. DC output is monitored with a variable intensity bulb or with a voltmeter connected to the binding posts provided.
