Let your class measure the velocity of sound in the air! After partially filling the resonance tube with water, sound a tuning fork of known frequency at the tube's open upper end. Then the water level can be adjusted until the air in the tube resonates at the same frequency as the tuning fork, increasing the volume of the sound.…
Strong ceramic donut magnets sealed in un-breakable colorful plastic cases. The North and South poles are located on opposite faces for ease of use. Can be used to determine if an object is magnetic. A set of 2 or more ring magnets can be used to demonstrate attraction and repulsion between poles, better known as the “Floating Magnets Experiment”. 1.25X.25”…
Transparent acrylic plastic ripple tank, supported in a sturdy plastic frame which has recesses to hold four legs with leveling feet. The tank edges are shaped to minimize undesired reflections. The tank has a drain hole closed by a rubber stopper. With two light alloy uprights to carry a horizontal ripple support rod that is adjustable for height. The ripple…

The unique design and size allow it to be used on an overhead projector as well. Supplied in foam packing and consists of the following components : Ripple Tank 40 x…
Demonstrates the typical concept behind the architecture of roman arch structures, which are famous for their strength in compressive loading. Comprises a pre-assembled 3-part buttress and a set of 23 wooden blocks. A fully assembled arch can easily support the weight of a child.
With effective scale lengths of nearly 9″, Rotary scales offer greater accuracy than linear scales. All balances are graduated in gram/Newton. Dial: 3″ diameter metal suspension ring at top and hook at bottom.
The heavy duty rotating platform illustrates the concept of rotational inertia. The platform can easily withstand weight of 80 kg. Solid, heavy metal legs and grooved platform ensures maximum stability.
To demonstrate the Second Law of Motion simply and accurately, two identical balls one drilled, and the other solid is used. When the release lever is triggered, the internal spring accelerates one ball and releases the other, showing that two balls dropped from the same height hit the ground at the same time even though one is traveling forward when…
