Principle
Electronystagmography (ENG) is an electrophysiological diagnostic procedure for measuring the movement of the eyes. Several electrodes measure the potential differences that are caused by the eye movements. When looking at a moving, regular, repetiti ...
Heavy-metal ions may be carried into surface or ground water from mining fields or via the waste water of galvanicor similar production sites. They block the effect of enzymes so that the processes in the metabolism of the organisms that are controlle ...
Demonstration experiment using wireless data transmission to a large digital to display. Heavy metal ions can seep into water courses, for example from galvanising plants or other similar industries. They have the effect of suppressing the action of enzyme ...
The heart is a hollow, muscular organ that comprises several secondary muscles. These secondary muscles contract and relax successively, thus pumping the blood through the heart. These muscle activities can be measured electrically as a whole at the ...
With the exception of the heart muscle, the contractions of striated muscles can be controlled at will. This characteristic enables the observation of the activities of individual muscle groups. An electromyogram (EMG) can be used to measure (record) ...
With this experiment, you can find evidence of the electrical activity that is generated during the movement of your eyes. Several electrodes attached to the skin of the face measure all the changes of the electrical voltage that are caused by the mov ...
These measurements help to quickly and simply introduce the term "heat capacity". The students learn on which characteristics temperature changes of surfaces depend. As practical example, reference can always be made here to the hot sand ...
Illustration of the heat loss for different relationships between volume and body surface area, using a model consisting of different sized round bottom flasks that are filled with water.
To prepare and analyse diagrams to illustrate the transpiration of plants, depending on different environmental conditions, using a wireless data acquisition system:
Representation of the photosynthesis rate of a plant by measuring the oxygen pressure increase, in white and green light as well as in the dark.
Investigating the temperature increase during the fermentation of sugar by yeast cells.
To examine the enzymatic decompositionof hydrogen peroxide, a cell respiratorypoison, in the liver.
Measurement of the photosynthesis rate as a function of light intensity by counting the oxygen bubbles that are released by a water plant.
The aim of this experiment is to prove glycolysis by means of measuring the CO2 production under various experimental conditions (temperature, pH).
The cell membrane controls the transport of nutrients and water into the cell as well as the transport of waste products and water out of the cell. This can be passive, i.e. caused by osmotic processes, as well as active. The aim of this experiment is ...
