Water quality - contamination with heavy metals

Principle

Heavy-metal ions may be carried into surface or ground water from mining fields or via the waste water of galvanic or similar production sites. They block the effect of enzymes so that the processes in the metabolism of the organisms that are controlled by these enzymes may ...

Weight with measureAPP



Principle

"A mass is not only inert but also heavy." Which is intended to mean that not only is a force necessary to accelerate a mass, but also that each mass in the earth's gravitional field experiences a force, the force of weight. The force of weight is to be measured ...

Bending of a leaf spring with measureAPP

Leaf springs are thin metal plates that are elastically deformed under load: When a force is applied to a
leaf spring, then it is subject to deformation. A characteristic of such an elastic deformation is that the
original shape is re-formed when the force is no longer active. In ...

Thermal equilibrium with measureAPP

Principle

Why do tea or coffee get cold onstanding, but never hot? The students watch, the water temperatures when a vessel containing cold water is dipped into a hot water bath.

Benefits

Thermal equilibrium with SMARTsense

Thermal insulation with measureAPP

A quick loss of heat is sometimes not wanted. What can be done to keep the temperature in a vessel
constant? Students are measuring the cooling of hot water in two different environments.

Heating of water with measureAPP

Principle

How depends the time required to heat up water on the amount of water when a defined heating source is available? The students are heating up various amounts of water with an electric heating coil and measure the time dependence of the ...
