Crop circles first appeared in the 1980s in farmers' fields in the UK and reports of them spread over the following decade across the world. The patterns were often geometric and complex, leading to theories that they were created by aliens, though they were likely human-made. Students used GeoGebra to model dynamic crop circles, though some geometries were too complex to create dynamically. Their files were uploaded to a GeoGebra project page on crop circles.

- 2. Crop circles modeled with GeoGebra What about crop circles? Where do we find them? Crop circles appeared in the early 1980s on farmers land in U. Reports in the media about crop circles all over the world exploded in the next 10 years. Mostly there are geometric pattern, very huge and sometimes full of complex math. There had been many theories about these crop circles and nobody really could expain how they were made So a lot of funny stories were told e.g. that these crop circles of course man-made were created by alien spaceships which landed on the ground.
- 3. Crop circles modeled with GeoGebra Students tried to create dynamic crop circles. But sometimes the geometry behind the forms are too Scomplex, to construct it dynamically, sometimes they did not pay attention for dynamic working. Some work has been coloured using PAINT (or a similiar working software). All Geogebra files will be uploaded to our GeoGebra space of the project: Crop circles GeoGebra
