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.
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…
Ever wonder how a clock works? For centuries the pendulum clock was used to keep time. The Simple Pendulum kit shows you why you can measure time with a ball and string and how to do it. Includes a tape measure, two different pendulum balls, six feet of string, and an activity guide. Ages 7+.
This student force table is a complete set with these new features: -Dual scale that allows students to take readings either clockwise or counterclockwise; Four complete weight sets (each contains 2 of 5g, 4 of 10g, 4 of 20g brass slotted weights and a 20g brass weight hanger), four pulleys with clamps and two sets of strings that allows students…
Designed to clamp to an upright support rod or crossbar. Tape, carbon discs and instructions are included. Size: 7”L x 2”W x 1 1/4 “H. With 38mm Carbon Disc (12)
Consists of two disks which can be loaded with up to 8 ball bearings in internal compartments. Load one disk symmetrically and the other non-symmetrically to show the difference. Instructions and eight solid balls included.
13 cm diameter molded wheel contains 4 grooves of different diameters in the ratios 1, 3, 5 & 7. The grooves are wide and flat bottomed ensuring an exact diameter for each groove, each comes with a small hole to retain the cord. The back of the wheel is hollow to minimize the mass and inertia. Wheel is attached to…
