parabolic trough
Description
https://www.youtube.com/watch?v=ifLrGgdMwfo&feature=youtu.be We, the natural sciences course (class 9) of the Herta-Lebenstein-Realschule designed a parabolic trough model. Among other things, a test facility was created on the subject of "thermal energy". In the so called parabolic trough, the light rays are focused on one point and now it heats e.g. a tube. Materials: - 14 washers - 14 mothers - 3 threaded rods (4mm) - Mirror foil The length of the parabolic trough can be adjusted by the threaded rod. We would also be very happy about constructive feedback!!! Take a look at our other projects.
