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 ...
"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 ...
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 A characteristic of such an elastic deformation is that the original shape is re-formed when the force is no longer active.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 ...
Especially understandable and didactic prepared experiment descriptions including protocol
Future-proof lessons: Integration of tablets in digital science lessons
Enhanced motivation of students due to the use of the intuitive measureAPP
Increase of ...
The students discover the directional dependency of hydrostatic pressure with the help of three different measuring probes.
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
· Especially ...
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.
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 ...
