A simple way to demonstrate parallel and series circuits.

An all-inclusive solution

A fascinating demonstration!

Demonstrate the conversion from electrical energy to mechanical energy

The determination of the gravitational constant ‘g’ is one of the most fundamental and early physical constants students must derive and observe. This kit has a wooden base, 1.1m rod and a movable electromagnet. The electromagnet can be moved anywhere on the rod and is powered by the timer. When the ball is released, the timer is triggered and stopped once the ball has landed on the base for a precise measurement and then calculation of ‘g’. Supplied with manual.

The Lenz's Law Kit investigates how much force an induced magnetic field can create.

Consists of two interconnected cylinders of different diameters based upon two graduated glass syringes of 10mL and 50mL, with cross-sectional area of 3 to 1.

Consists of one support, 5 plumb lines, 1 roll of tape, and 5 figures (triangle, L, trapezoid, parallelogram, parallelopiped). This kit helps students in the individual research of the center of gravity of a flat body, the conservation of the result on paper, the possibility of a graphic verification, and the discovery of the geometric research method.

Studying dynamic tension has never been easier with this simple form truss kit. The kit includes a half-meter truss with hooks on both sides, V-shaped clamp.Recommended stand and rod, item 470137-892 Required but not included are masses and spring scale.

For demonstrating the differential expansion of two metals as shown by the curvature produced when the bar is heated. Each metal band is 200 x 15mm and riveted together.

Right angle and equilateral prisms are available in a variety of forms.

Spectrometer prisms offer a different index of refraction for every need.

Introduce students to different standing waves.

Measure an electric current by determining the magnitude and direction of the horizontal component of Earth’s magnetic field. Set the compass needle parallel to the coil, pass an unknown current through, and measure the angle of deflection. Features copper magnet wire, adjustable potentiometer, compass, and non-magnetic stand. Required but not included is one D battery.

Made of brass, interchangeable on pillars, fitted with insulators of ebonite on base. Spheres 5cm diameter, Cylinder 12.5 x 5cm diameter, Cone 10 x 5cm length x diameter.

Multiple value resistances with 4mm sockets
