Teaches mechanical vibration and waves. Use the set to teach about transverse and longitudinal standing waves as well as the concept of resonance, and mechanical vibration. The sine wave signal generator has a large 3-digit display and is combined with the vibration generator for low- and high-frequency vibrations with a range of 1–400 Hz (1-Hz increments) and 0.01–4.00 kHz (0.01-kHz increments).

This microscope does not need batteries but uses more natural lighting means, it is perfect for indoor and outdoor use. The base and arm are made of cast alloy with a baked enamel finish; the 10X wide-field eyepiece combines with the 4X objective for 40X magnification. Spring-loaded clips hold specimens in place on the stage, with a sliding barrel focus adjustment, an arm that tilts 45 to 90, and a mounted plastic prism collects light for viewing.
• 10x eyepiece
• 4x objective
• 4″ x 5.5″ x 10.5″
• 2.5 lb

This 8’’ glass globe is filled with an inert gas under low pressure. The lightning bolts are produced by the Tesla coil in the middle that creates a large potential difference within the globe.
• Comes with a detachable power supply. AC 12V 500mA UL Adaptor, 220V Dimensions:
• Diameter of the globe approx. 8″ (200 mm)
This set of slotted masses includes nine 50 g disks and a 50 g hook. Total weight: 500 g. This set is useful for weighing and measuring masses in general science and physics laboratory work. It is an ideal tool for studying Newton’s Laws of Motion, general mechanics, machines, and kinetic energy.
Students can duplicate the individual processes of the water cycle (evaporation, condensation, and precipitation) with this model. Accompanying set of ten 8 1/2 × 11″, full-color study prints and transparency will broaden students’ understanding of the water cycle and enhance awareness of the various states of water.
This portable unit is outstanding for demonstrating stream erosion and deposition of soils either in the classroom or outside. Kit includes a plastic tray, drain trough, tray support, and siphon tube. Order sand separately.
