Principle
A capacitor is a passive electric component with the ability to store electrical charge and so the corresponding energy.
Task
How can solar energy be stored without using a rechargeable battery?
Try to sto ...
Energy can be transmitted through heat convection, heat radiation or heat conduction. The greater the thermal conductivity of a wall, the higher the temperature of its exterior. This property is used to compare the temperatures and thus the thermal c ...
In this experiment a white tent in the desert will be simulated by means of a white absorber plate which is exposed under a halogen lamp for 5 minutes. The temperature difference before and after the irradiation is compared to that of a black absorber ...
The temperature increase is much higher in the case of the insulated plate as opposed to the uncovered plate. When the plate is not insulated, it can lose heat energy to air flowing by and through the radiation of heat.
Task ...
The greenhouse effect in the solar collector works not only for the better heat insulation of the solar collector, but also for its protection from the external influences of the weather. The heating is not significantly influenced by the plexiglass d ...
A small beaker with water is placed in a model solar collector. Observe how well the water in the beaker can be heated up.
How can one heat up water with a solar collector?
In this experiment a heated up room or house are to be simulated. The solar collector from the Pupil Kit is used for this purpose. Three walls are made up of Styropor, the front plastic plate is the window. The black beaker with hot water serves as " ...
This experiment explains the principle of the greenhouse effect. At a surface temperature of about 5600°C, the sun mainly irradiates heat radiation in an area of 500 nm in the direction of the Earth direction. The terrestrial atmosphere allows the rad ...
Experiment using a model to generate electrical energy with the help of a windmill.
A lamp is connected to the wind generator to act as a load and the brightness of the lamp is observed for various different wind speeds.
In this experiment a wind wheel is set up at various distances from the blower. The wind that reaches the wind wheel has different speeds.
What influence does the wind speed have on the voltage produced ...
The blower (fan) produces wind of constant strength and the wind wheel is located in a fixed distance from the blower. The wind direction is changed by turning the wind wheel. Examine how the voltage generated by the wind wheel behaves in response to ...
The wind wheel is operated by means of a blower and a connected "consumer" (for example a light bulb or a LED) is light up. Observe the wind wheel with and without consumer.
Observe the wind wheel when it opera ...
From their environment, students usually know of wind turbines that have 3 blades. There are also models with only 2 blades or with completely different structures. In contrast, water wheels have more blades ("Blätter"), and they are suitable for driv ...
Accumulators exist at different states of charge. Before you begin with the experiment, make sure that the accumulator's charge is low enough so that the glow lamp does not glow at the beginning of the experiment. If it glows, the accu can be discharg ...
