Sunflower activity pdf from BBSRC
 

This activity pdf from BBSRC.ac.uk is great.

It's a pdf with highly structured content with some core knowledge for providers and although it has a recommended age of 5 - 7yr olds it provides an excellent opportunity to see how free flow or impartial resources can be supplied for children to take up, build & assemble their own Sunflowers.
