Cylindrical body to demonstrate the temperature dependence of buoyancy.

If the body is placed in a vessel filled with cold (approx. 10 °C) water, the body will float.

If the body is placed in a vessel filled with hot (ca. 90 °C) water, the body sinks to the bottom.

At a temperature of about 50 °C, the body begins to rise to the surface in the vessel.

Metal cylinders of equal mass for density determination.

In the box, the cylinders are marked and equipped with a hole for hanging on a thread.

Material: Al, Cu, Fe, Ms, Sn

Weight of cylinders: a' 15 g

The set contains 2 cylindrical bodies and two 100ml measuring cylinders.

If the body is placed in a measuring cylinder filled with cold (approx. 10 °C) water, the body floats.

If the body is placed in a measuring cylinder filled with hot (ca. 90 °C) water, the body sinks to the bottom.

At a temperature of about 50 °C, the body begins to rise to the surface.

Tubular dynamometer. The length of the pipe part is 210mm, the length of the scale is 100mm.

Spring 20 N/m. Max load 8 N. Length 180-185 mm, diameter: 12 mm

Spring 86 N/m, max load 13.5 N. Length 95 mm, diameter 10 mm.

This case contains an easy-to-use collection of measuring devices that can be used in primary school wherever temperature, weight and length need to be learned and measured. It has proven itself in physical education in physical and biological studies, but also in mathematics lessons.

The pupils can acquire elementary and contemporary knowledge about measurement conventions as well as the functioning and use of measuring devices. In a "measurement triathlon" they demonstrate that they can select the right measuring device, use it properly and record the results.

Materials for 15 work groups

The kit provides simple seesaws, beam balances, spring balances, dial balances and balance beam (lever) calculating machines. Children learn some historical and physical aspects of scales and weighing. 

They also learn 

ƒ to understand the principle of a seesaw 

ƒ to assemble and use a beam balance 

ƒ to calculate with a system of measures 

ƒ a common system of measures 

ƒ to appreciate the advantages of a common system of measures.

Some examples of experiments: 

ƒ from seesaw to balance 

ƒ beam balance 

ƒ Egyptian balance 

ƒ Roman balance 

ƒ Spring scale with calibration 

ƒ Calculator balance (equal-arm lever) 

ƒ Calculator balance (unequal-arm lever)

For easier experiments with a vacuum.

The wave demonstration device is attached to a table with a clamp or held in place by an assistant. The other end of the string coming from the device is fixed securely at a suitable length or held by another assistant. A DC voltage of 6V is applied to the device and by adjusting the rheostat, standing waves are achieved in the taut string.
