Solar collector, student model
Solar collector, student modelThis small solar collector is a simple and clear model that introduces the fundamental concepts. The solar thermal collector operates with a stationary amount of water that is heated when the rays of the sun hits a black aluminium absorber.
Solar System model
Solar System modelThree-dimensional model of our solar system with the 8 planets.
The model is suitable for giving students an understanding of size ratios, distances, colors and speed when the planets revolve around the Sun.
With the model, you can easily explain why some planets are only visible for part of the year.
Solar System, inflatable
Solar System, inflatableInflatable beachball models of the Sun, the planets, Pluto and the Moon – 11 celestial bodies in all.
Solar thermal collector, complete
Solar thermal collector, completeAn improved model of our plate solar thermal collector, for both qualitative and quantitative experiments.
