Cornelsen Experimenta 31780 Science kit

Experimental case for scales and balance
With this extensive experimenting material you as teacher and teacher have the opportunity to bring your students of the 2 and 3 class closer to the different types of scales: Rocker, bar balance, spring balance, fast balance and calculating balance (lever) in their simplest forms. The students acquire practical skills in the handling of weights and at the same time practice the calculation with the measuring system.

The experimenting case is designed for 15 learning groups (each 2 to 3 learners) and the materials are clearly arranged. A comprehensive guide supplements the case and supports you in preparations and in lessons.

The students learn:

Understanding the principle of the rocker and recognizing the transition from horizontal to vertical support – from the rocker to the scale.
Assemble a beam scale made of individual parts and balance it with the help of the tare slider.
To determine which objects are heavier, lighter or equal weight, use the scale and the weight pieces.
To learn about our system of measurements and to understand the advantages of uniform measurement systems.
Make comparisons to everyday objects and explore the application in everyday life.
