Open Case Form Electroscope
Charge is indicated by deflection of an aluminized plastic straw which rotates freely on the saddle of the conducting rod. A scale on the instruments back is graduated in degrees to allow measurement of the deflection. The conducting rod is recessed in the metal housing to shield against air currents. With replacements aluminized straws.

Open Pit Mine Model
Open pit mining often results in a large hole, or pit being formed in the process of extracting a mineral. Deposits mined by open pit techniques are generally divided into horizontal layers called benches. The thickness of the benches depends on the type of deposit & the mineral being mined. Mining is generally conducted on a number of levels at any one time.
