# Containerbrücke (linear)

A very simple cardboard-model of a container bridge helps pupils upwards from age 10 to begin and understand the specific roles of independent and dependent variables. The idea is to find a function or term which maps x to y. In this case, the solution will be a linear function with a negative gradient. This, however, will require skills usually only present from the age of 14 and upwards.
