There are tutorials from Italian students of grade 9 how to construct petal flowers and how to create a tool for these wonderful models of flowers.
There are also applets that students who don't know anything about this way of construction petals can explore with fun!
GeoGebra applet based on polar coordinates created by Brian Sterr: LINK
There are some questions that students- though not knowing anything about this- can explore, e.g
- the influence of r concerning the flowers
- the influence if b is an odd, even number
- relation between be and number of petals
