The Inertial Balance allows for the measurement of inertial mass. Adding mass to one end increases its inertia and causes it to oscillate at a slower rate. This apparatus allows for the investigation of masses by comparing the oscillation period of a known mass to the oscillation period of an...
The design of the SpillNot™ uses the principles of Newtonian physics to keep the liquid in the container. The flexible handle and the location of the suspension point above the center of the tray ensure that the forces on the liquid are always directed towards the supporting tray, even when...
This Whiteboard Globe has a write-on dry-erase surface that allows for students and instructors to directly mark on the it. Marks can easily be erased with a soft cloth. Permanently printed on the globe are markings signifying continents, country and state borders, rivers, lakes, deserts, currents,...
Electroscopes are used to detect and roughly measure the electric charge on an item. This aluminum-leaf electroscope has a metal case with a round viewing window. Replacement foil is also available. PRODUCT WARNINGS WARNING: This product can expose you to chemicals including styrene, nickel, and...
Made from Plate Glass, with carefully ground and polished optical survaces, and cleanly ground edges, these lenses feature a diameter of 38mm - 125mm and focal lengths from 50mm - 500mm.
1216T40 (DCSET4): This set includes one each of acrylic, pine, nylon, and aluminum cubes packaged in a poly bag. Includes a reference table showing density values of individual specimens. 1216T39 (DCSET10): This set of 1" cubes includes one each of acrylic, oak, pine, poplar, steel, aluminum,...
Made from plate glass about 2mm thick with highly silvered back.
A visual demonstration of buoyancy and atmospheric pressure. A glass Cartesian diver 2.5" tall rises and lowers in a column of water as the pressure is increased and decreased. Increased pressure is obtained by compressing a rubber sheet stretched over a water filled cylinder. A red band around the...
Tuning forks made from alluminum alloy. The frequency and leter scale is stamped on each fork.
Demonstrate storage of electrical charges! This unit is effective in helping students understand the function of a dielectric and the buildup of static electricity. The inner and outer metal conductors are separated by a plastic insulator cup. These pieces slide easily in and out of one another. The...
Our Radiometer is made from a glass bulb from which much of the air has been removed. Inside the bulb, on a low-friction spindle, is a rotor with 4 vanes. Each vane has one blackened side and one silvered side; one black vane features a white dot in order to count rotations easily. When exposed to...
Helmholtz coils are useful for creating near-uniform magnetic fields or for cancelling out external magnetic fields, such as the earth’s. The field between the two solenoids is at its most uniform when the distance between them is equal to the radius of the solenoids. This can also be used with a...
Telegraph key, mounted on a solid plastic base, measuring 11cm x 5cm.
Featured displays of this electronic alarm stopwatch include time (hours-minutes-seconds, with 12 or 24 hour mode option), calendar, 24-hour stopwatch, alarm, hourly chime, 1/100 second chronograph, split time, and total time.
