Comparison of the heat capacities of water and soil

Principle

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 ...

The Bergmann rule: heat loss as a function of the body surface area and volume

Principle

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.

Impact of the forest type on humidity, temperature and brightness

Principle

Various types of woodland exhibit different sorts of climate data. Temperature, humidity and lighting conditions do not only depend on meteorological factors but also on the nature of the vegetation. The density of the tree canopy determines how much light can penet ...

The Bergmann rule: heat loss as a function of the body sur face area and volume (with the Cobra3 Basic-Unit)

Principle

Demonstration of different heat losses in dependence on body surface area and volume.

Tasks

1. To prepare a graph which demonstrates the different heat losses with different volumes and body surface areas.
2. To inter ...

The insulating effect of body coverage (with the Cobra3 Basic-Unit)

Principle 

Demonstration of the insulating effect of bodey coverage.

Tasks

1. To prepare curves showing the insulation effect of various body coverage's.
2. To discuss the reason of different isolating characteristics.

The insulating effect of body coverage (with the Cobra3 Chem-Unit)

Principle 

Demonstration of the insulating effect of body coverage.

Tasks

1. To prepare curves showing the insulation effect of various body coverage's.
2. To discuss the reason of different isolating characteristics.

The twenty-four-hour rhythm of an aquatic plant (with the Cobra3 Chem-Unit)

Principle

Plants produce oxygen by photosynthesis under the influence of light (during the day). Carbon dioxide is hereby consumed. In the dark (at night), however, they consume oxygen and produce carbon dioxide.

Tasks

1. This day and night rhythm ...
