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.
1 - Celsius and Fahrenheit
2 - Build a thermometer yourself
3 - Build a reading trainer for thermometer scales
4 - ideas for temperature measurements
5 - Measure temperatures at home
6 - Solve tasks for measurement masters
7 - Weighing with the beam scale
8 - Build your own rocker scale
9 - See through the quick scales and use them correctly
10 - Determine the weight of sleeping folders
11 - How do you know how long a meter is?
12 - Make a tape measure for your pocket
13 - We measure each other / measuring tasks with the measuring tape
14 - Measure with the caliper out of the box
15 - Build a caliper yourself

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)
